Changelog
ArchiDroid 2.4.3
- Improved archidroid_pixelserv
# Previously archidroid_pixelserv responded to all requests with the same 1x1 NULLGIF response (GIF89a[]![])
# This was OK but in some apps it showed our gif in binary form (GIF89a[]![]) instead of showing nothing, i.e. in Subway Surfers game
# Now we respond with a "NULL" content proper for request
# If app requests JPG, we respond with NULLJPG, if app requests TEXT, we respond with NULLTEXT etc.
# This way app "gets what it wants" and won't show something, which it can't understand to user
# Surprisingly, at least Subway Surfers doesn't show any ad right now, so it also stops some apps from displaying NULL content, instead of showing NULL in binary form
- Removed VNC Viewer
- Updated ArchiDroid Backend tools (dnsmasq, haveged, dnsproxy2, pixelserv) to latest versions
- Updated PA GAPPS to 0417
- Used Carbon as base; Omni is maybe coming in future (if requested; this eventually needs much time)

[SIZE="+1"]Features / Why ArchiDroid?[/SIZE]
First of all, ArchiDroid includes everything available in it's base. The whole point of ArchiDroid is to improve the base, without needing of making any trade-offs, so by flashing ArchiDroid, you're getting everything offered by the base itself. There's nothing to lose, everything to gain.
You can read detailed information about every ArchiDroid component here. It's a massive wall of text, so I'm only going to list the core features without describing them.
These were written from scratch, they're completely unique and you won't find exactly the same implementation in any other ROM.
ArchiDroid-Unique features:
- ArchiDroid's AROMA Installer
- ArchiDroid's Pocket Debian
- ArchiDroid's Flasher
- ArchiDroid's RunOnce
- ArchiDroid's Init
- ArchiDroid's Backend Control

- ArchiDroid's Fast Random Number Generator (Frandom)
- ArchiDroid's Adblock (dnsmasq/dnrd, dnsproxy2, pixelserv)
- ArchiDroid's Forced Update
Apart from that, here, on the credits page, you can find all third-party projects, which have been implemented into ArchiDroid. In addition to that, it's up to YOU to decide if you want to install something, or not.
ArchiDroid focuses on flexibility and user choice.

Especially:
ArchiDroid is one of the most complex ROMs ever created. When you start digging in my work, you can very easily get lost. And I'm not talking about base itself, but about everything next to it. You can use every part of my work, as long as:
1. You include proper credit where you should. This usually includes proper comment in a script/file and in the credits of the project, including license (if needed)
2. You let me know about this fact. Through PM on xda or e-mail
I'm always happy to help, especially with the problems I faced in the past. However I also want to be respected, considering that most of the ArchiDroid parts were written from scratch.
Know Your ArchiDroid
ArchiDroid is not only a rom. It's not only a baked android with third-party apps, modifications and tweaks. ArchiDroid is an universal backend which improves rom by many built-in functions.
Let me tell you a story. During developing first version of ArchiDroid 2.0 I experienced many problems, which were not that easy to solve. First of all - apps data. Trust me or not but you can't simply extract data, put it in /data/data after install and hope that it works. Android will detect such injection, report inconsistent of data and wipe everything attached to that. Okay so... How I should provide you with my boeffla preset? CoolTool settings? STweaks profile? If I put my data during flashing it'll get wiped. If I put my data and deny wiping it then Android will report inconsistent of data to user and work unstable. Yes guys, it's impossible to do so without a trick or without recompiling whole rom.
I won't tell you a whole story, because you probably don't want to hear about ArchiDroid development. I'll simply tell you that I overcome MANY difficulties, simply because I do what I like, and I like what I do. After countless number of hours, I can finally provide you with the ROM, which is the best. Why is it the best? Because I'm improving the base, and I'm not making any trade-offs.
GitHub / Versioning / Experimental Versions
You can easily "pack" latest experimental and flash without needing to wait for the next build. I'll tell you how to download and flash it by yourself.
[Newbie Version]
1. Open 2.X-EXPERIMENTAL branch.
2. Click on Download Zip button located in bottom-right corner.
3. Install 7-Zip if you don't have that already. Other programs may, or may not work correctly.
4. Right-Click on zip, select Extract Here
5. Navigate to newly created ArchiDroid-2.X-EXPERIMENTAL folder
6. Select all files WITHOUT __dont_include folder, right-click and select 7-Zip => Add to archive
7. Make sure that you have zip format, Fastest compression (to save some megabytes) and Deflate method of compression.
8. Voila, copy newly created ArchiDroid-2.X-EXPERIMENTAL.zip to your phone and flash as usual.
[Expert Version]
1. Install Git for Windows or Linux
2. If you're on windows then make sure that windows won't change LF into CRLF (git config --global core.autocrlf false)
3. Clone my git repository using .git file. Keep in mind to specify depth, as this repo is really big. (git clone https://github.com/andreasltcf/ArchiDroid.git --branch 2.X-EXPERIMENTAL --depth 1)
4. Select all files WITHOUT __dont_include folder zip them into standard .zip format with Deflate compression or without any compression.
5. Copy .zip to your phone and flash as usual
6. In order to update your local repo execute git pull origin 2.X-EXPERIMENTAL and go to point 4.
Additionally you can watch @JustArchi's short video, which shows how to flash experimental ArchiDroid going through "Expert Version" (Archi's GitHub).

ArchiDroid Features
Know your ArchiDroid, learn how to use it
Introduction / Basics
Welcome to ArchiDroid's world mortal. In this tutorial we will show you what ArchiDroid has "inside" and what it really offers. All of things included in this post are ArchiDroid-specific, which means that you won't find any ROM with the same features, as they're written from scratch.
Here you can find some definitions of the words used in sections below. You should know most of them, but in case somebody is lost here you can get back on track.
Terminal, Shell - Typical android shell, which may be obtained in three ways.
1. Through native Android Debug Bridge (ADB) with command "adb shell" from the PC or even "ADB through network" (if supported).
2. Through any Android terminal app, f.e. Android Terminal Emulator bundled with ArchiDroid.
3. Through secure shell daemon (sshd), which needs to be turned on firstly. This is extremely useful in terms of pocket debian, which will be described later.
You can use any of these methods to access android's terminal, however usually Android Terminal Emulator will be the easiest one, as it's android app bundled with ArchiDroid. WARNING! Most of the commands below WILL require root access. You can log in to super user shell by "su" command right after obtaining shell. If you're unsure if you're logged as root or not, "whoami" command should print actual user, "root" or "unknown uid 0" are OK, others are not.
ArchiDroid's Pocket Debian
From wikipedia:
From debian site:
How exactly this covers our beloved SGS3 (and countless number of other android arm-based phones)?
As you may (or even should!) know, Android operates on it's own Linux-based kernel. Android's kernel is literally a fork of Linux kernel, with a few special/unique functions which are required, mostly hardware-specific. Because of that kernel itself is VERY compatible with everything based on Linux.
However there have always existed one typical problem, lack of proper environment. We have a great kernel, great power, linux-based android environment, but this environment lacks of very common and required libraries/binaries. If you ever wondered what is or what does busybox, this is the answer. Busybox is just a small package which offers a few standalone GNU/Linux binaries, which are required to make certain things work. For example, swap priorities. Android knows what swap is, and nothing else. It doesn't know that swap could have a priority, so if you use android's swapon command on 4 devices, it will firstly fill first device, and then proceed to the next. That's why we need busybox in ALL custom kernels, because android environment isn't enough.
However busybox sometimes isn't enough. If we focus only on Android itself, it is. But if you for example want to run stricly linux-based service, I don't know, a web server for example... Is it possible to run a native linux web server on an android? No, it's not. You should firstly compile such service on arm architecture, including all dynamic and static libraries (wrrr ) in it only to finally get mad because of missing libraries or other dependencies. Of course if you're patient you'd finally compile everything and set up, however how long would it take? A few days maybe? If you're skilled in what you're doing...
This is why I included built-in "pocket" debian in ArchiDroid. It's FULLY compatible with everything compiled/based on armhf/armel GNU/Linux architecture, for example Raspberry Pi. With two easy commands you can literally jump into debian environment and use every typical GNU/Linux utilities known from debian itself. Of course this means nothing for most of the users, because they'll never have any reason to use such debian environment but from the developer side, it's big step forward. The best example is with github. As you know ArchiDroid has it's own repo on github, from where you can download/manage stuff. There also exists git app for linux and windows. If you want to follow "expert" way of flashing experimental ArchiDroid version, such program is required. The scenario is the same as compiling web server for an android, it requires much more effort than it's worth. And even then you can end up with syncing external dependencies and searching for solutions for the problems you've never seen before... And with ArchiDroid's pocket debian? It's as simple as in any debian/ubuntu distro. "apt-get update && apt-get install git" and voila. Your git is installed and ready for work. Going further I've even included git in pocket debian itself. Okay, I have debian, I have git, and what next? With git utility I can for example provide you with delta updates for ArchiDroid! ArchiDroid can easily use pocket debian to set up and sync ArchiDroid's repository and then pack and flash latest version without even needing of a PC, using 7-zip or anything else. Another example? A web server. I know that it's very dev-specific but if you for any reason need a web server running, just for example to test simple website, you can have it with just one command. Going further, VNC? MySQL server? PHP? Python? Perl? Ruby? Maybe conditional tasks with cron? Persistent minimal IRC client? rtorrent with rutorrent GUI over WWW? The list goes on... Anything based on linux will work. You can even host a server for your favourite game, as long as it has armhf/armel binaries (unfortunately most of the games don't).
So that's it. In short, debian is an operating system built-in in ArchiDroid to provide you with (unfortunately missing) GNU/Linux environment, with full power, ready to handle anything you could request. I made my best to include fully working debian in ArchiDroid for a minimal cost. Whole OS is packed in one big tar file, compressed using highest bzip2. As for now pocket debian has ONLY 40 megabytes of size, maybe in future it will have up to 50 megabytes, but no more. It's a VERY small cost for having such great power, especially if you know how to use it.
This is a really cutting-edge feature, mostly because I have no limitiations what I can include in my ROM right now, and while other developers are dealing with OpenDelta updates and many Android-based problems, I'm just launching my pocket debian and manages linux stuff.
I'm SURE that most of the advanced ArchiDroid user will just LOVE this feature, as much as I love it. I'm looking forward to your responses how YOU use pocket debian with your ArchiDroid. It's also a great time to learn what does the debian offer and how you can simplify your common tasks with just one example debian utility .
Technical informations:
1. Pocket Debian does not cause any additional overhead. We don't need to use emulation, neither virtualization to boot our monster. I used chroot technology to "jump" into debian environment with already running kernel and Android. That means additional required CPU/RAM is based on what you run in pocket debian. Booting itself doesn't require anything, just about one megabyte of ram for /bin/bash shell .
2. Android has some restrictions, mostly sockets. It doesn't allow to create inet sockets by default, even for root users. You will need to add your custom debian users to special group called "inet" (GID 3003) to allow creating of inet sockets, and you may also need to add a group to net_raw group (GID 3004) to allow creating of raw sockets. Please keep in mind that it's only required if you're running an app which required it's own socket, for example mysql server. So apt-get install mysql-server will fail right after booting, you will need to use "addgroup mysql inet" and then apt-get -f install to complete installation. Of course "mysql" is the new user under which mysql-server really operates. I've added root to both of these groups by default.
3. The only "real" restriction is the kernel. Our debian uses Android kernel and it's filesystem. It should work with most common tasks but in some cases our kernel may lack specific modules or built-in code, for example tun/tap required for OpenVPN. Still it's enough to run pretty much everything and if you get in touch with your favourite kernel developer you can also kindly ask for specific missing things.
4. Debian is built and included thanks to debootstrap utility, ArchiDroid command used for creating debian environment is debootstrap --verbose --arch armhf --include=git,ca-certificates,ssh,htop,tightvncserver,xterm,xfonts-base --exclude=manpages,man-db,rsyslog,vim-common,vim-tiny testing debian http://ftp.fr.debian.org/debian
HowTo:
Pocket Debian contains two main terminal commands, "adlinux" and "debian". Both of them are described below. By adlinux and debian you boot and jump into debian's chroot, which means you can use any debian-specific commands.
Examples:
passwd - changes password of actual user. This is needed to login as specific user, for example through ssh.
service ssh start - starts local SSH (secure shell) daemon on native port :22, to which you can easily access via any client supporting ssh, f.e. PuTTY. So basicly after you start shell you can literally connect to your local area network (LAN) IP on port 22 f.e. through PuTTY from your PC.
ifconfig - prints network-related informations about online interfaces, including your local IP, which may be useful for connecting to SSH.
htop - Enhanced top utility. Gives you very good terminal-based view on actual running processes, used ram, load, and more.
apt-get update - Syncs with debian's apt repository. This is mandatory to use many of apt commands because ArchiDroid's debian comes without local repo available, however fully configured to download and access it with just one command
apt-get install XXX - installs packet XXX from debian's repository.
apt-cache search XXX - searches for all packets including keyword "XXX". Ultra useful in terms of searching for specific packet.
Please note that pocket debian is VERY similar to normal native Debian/Ubuntu distribution, therefore above commands are not ArchiDroid's magic, they're very widely used in Debian/Ubuntu distros. If you want to learn more, most of the Debian/Ubuntu tutorials will be very helpful.
ArchiDroid's Pocket Debian Booter (adlinux)
You can call "adlinux" command from your favourite terminal.
adlinux is designed to boot and prepare ArchiDroid's Pocket Debian environment. It requires mode to be specified, and also respects any extra arguments passed.
If you call standalone "adlinux" command then it will print usage and then ask you what you want to do with giving proper informations about every choice. Additionally if you know what you want to do, you can also pass arguments directly to adlinux command, f.e. by executing "adlinux default", which will execute adlinux with "default" mode.
Available modes:
default - Will mount /data /system /storage/sdcard0 /storage/sdcard1 and core filesystems in chroot. Default suggested mode
safe - Will mount only core filesystems in chroot. Useful if you don't want to share your storage in chroot
bare - Won't mount even core filesystems such as /proc /dev or /sys. Requires "debian force" to enter chroot. This is the "real" safe mode. You won't be able to interact with an android in any way, while debian itself will work in very limited environment, making core functions unavailable. Suggested only for testing purposes
rebuild - Will automatically reboot your device and remove debian folder in the safe way. WILL CAUSE ALL DEBIAN DATA TO BE LOST!
unmount - Will automatically reboot your device to safely unmount debian environment
Extra options:
extsd - Use external sd card (/storage/sdcard1 /storage/extSdCard), if possible
intsd - Use internal sd card (/data/media/0)
Additional information about modes:
Debian shares core kernel filesystems in "safe" and "default" modes, while it also shares your internal and external sd card in "default" mode. This is nothing to be scared of, as you have full control of what you run in debian, however please note that you CAN'T do whatever you want. All mounted partitions in debian are "binded". "Bind" means that it's mirrored to the mount point and all changes on mounted partition WILL affect the mount point, which is logical. This is nothing to be scared of, as long as you know that debian only extends your environment, it does not fully works in it's own and you CAN cause serious problems from inside of chroot. The only really safe mode is "bare" mode, however in "bare" mode debian can't really do anything, as kernel filesystems are absolutely required for most of the functions. Okay so, you need to know one thing. If you have booted debian you SHOULD NOT touch debian's folder, which is ArchiDroid/debian (on your internal or external sd card, depends what you choosed).. As you know debian for example binds /data to it's folder /data, which is physically ArchiDroid/debian/data. If you for example delete ArchiDroid/debian through root explorer WITH mounted debian then it will ALSO delete debian/data folder, which is binded to /data, and therefore will delete your whole internal sd card, that's why it's extremely important to take care because booted debian becomes part of the android and deleting it can cause at least soft bricks, with a possibility of hard as well. If you want to delete debian folder PLEASE use "rebuild" mode, only through this way you're absolutely sure that nothing bad happens and you won't delete your whole system partition by accident.
Note about extsd option:
Debian requires symlink functionality, typically native windows filesystems DON'T support symlinks, therefore you need to have your external sd card formatted in one of the native linux filesystems, f.e. ext4. adlinux will automatically tell you if debian can be unpacked and used on your external sd card, however it won't be possible under most common filesystems, such as exFAT or FAT32.
Technical informations:
1. Pocket debian archive is located in ArchiDroid/System/debian.tar.gz file. This is "bare" system used for creating environment for the first time, you should not touch it.
2. adlinux detects if debian is already extracted when booting, if not, it's firstly extracted from the file described above.
3. After extracting (if required), core filesystems are mounted with "bind" option based on the mode you've selected in "mode" question above. Typically it mounts /data /system /storage/sdcard0 /storage/sdcard1 /storage/extSdCard /dev /proc /sys.
4. Unmounting is not fully supported right now (linux barrier), therefore both "unmount" and "rebuild" options require a restart to execute properly.
ArchiDroid's Pocket Debian Shell/Chroot (debian)
You can call "debian" command from your favourite terminal.
debian command is designed to allow you "jumping" into debian chroot created by adlinux. Please read how adlinux command works firstly if you haven't done that already. debian command checks if core filesystems are available (if debian is booted), and if they are then it firstly modifies required environment variables to make debian happy (such as TERM, HOME, PATH), then it changes root (chroots) into debian folder, therefore allowing you to execute everything from inside of chroot. It's very generic command, therefore standalone "debian" command won't give you a choice the way adlinux did.
Available options (parameters):
force - required for jumping into bare debian, created with "adlinux bare" command above. This skips debian checks for mounted core filesystems, normally you should avoid it at all cost, unless you know what you're doing. If core filesystems are missing then it's very likely that your debian will be disabled in more than 90%.
extsd - Use external sd card (/storage/sdcard1 /storage/extSdCard), if possible
intsd - Use internal sd card (/data/media/0)
cmd - Executes command in debian chroot
WARNING! cmd parameter will cause all further parameters to be threated as a command passed to debian, therefore you need to make sure that this is the last debian parameter which you want. For example "debian force cmd service ssh start" will skip filesystems checks and execute "service ssh start" in debian's chroot, however "debian cmd force service ssh start" will pass "force service ssh start" to debian, therefore respecting filesystems checks and passing invalid command.
This function is extremely useful for making init.d and other startup scripts. For example you can easily call "adlinux default" and then "debian cmd service ssh start" to call secure shell daemon on every boot with two easy steps.
Technical informations:
1. debian command uses chroot technology to change root of current shell to debian shell.
2. After chrooting to debian directory, /bin/bash shell is automatically called as default debian shell.
ArchiDroid's Flasher (adflash)
You can call "adflash" command from your favourite terminal.
adflash is a great small utility, which allows you to easily update your ArchiDroid to latest stable or experimental version with one easy command and delta upgrade. It utilizes ArchiDroid functions, therefore you must be running ArchiDroid to use it.
If you call standalone "adflash" command then it will print usage and then ask you what you want to do with giving proper informations about every choice. Additionally if you know what you want to do, you can also pass arguments directly to adflash command, f.e. by executing "adflash 2e git", which will execute adflash with 2.X-EXPERIMENTAL version using git mode.
Available versions:
2e - 2.X-EXPERIMENTAL
2s - 2.X-STABLE
1e - 1.X-EXPERIMENTAL
1s - 1.X-STABLE
Extra options:
git - Sets up local git repository, which gives you delta upgrades and bandwidth saving
direct - Downloads targeted branch as .zip file directly from github
clean - Cleans everything up, including local repo and tmp folder from ArchiDroid directory specified below
extsd - Use external sd card (/storage/sdcard1 /storage/extSdCard)
intsd - Use internal sd card (/data/media/0)
nozip - Shows changelog and changes only
Okay so, the most interesting option is the mode...
Direct mode is simple, fast and effective. It downloads target version (stable or experimental) from GitHub server, then it repacks downloaded zip file and makes it available for flash. You should use this mode for one-time downloads, such as once per stable version or two. The only advantage of this method is the ability to download from github (and with one command).
Git mode is complex. It uses ArchiDroid's Pocket Debian (read above) for cloning and updating local ArchiDroid repo. This gives several number of advantages, mostly for using experimental versions. Firstly, by having local ArchiDroid repo you have to download ONLY changes between your snapshot and server's snapshot, which means delta upgrades. Secondly, you have access to all commits from target branch, so you know exactly what has changed since your latest download. Again, this is extremely useful for experimental branch, as changelog may not be up-to-date. Keep in mind that git mode will require additional space on your device for keeping ArchiDroid repository, therefore you sacrifice some space for delta upgrades. This mode is extremely useful for flashing ArchiDroid often, for example daily experimental versions, because in fact you download only new commits instead of whole repo/archive.
ArchiDroid's RunOnce (Backend)
ArchiDroid's Init (Backend)
ArchiDroid's Backend Control
ArchiDroid Backend Control is a set of settings, which controls behaviour of ArchiDroid's Init. It's located in /system/archidroid/dev and contains a number of files, which are recognized by ArchiDroid's Init. You shouldn't directly touch /system/archidroid/dev, instead you can control behaviour of ArchiDroid's Backend through /system/archidroid/scripts. They can be easily executed through any script manager, f.e. Root Browser or Android Terminal Emulator. Some of the settings are also located in /system/archidroid/etc folder, mostly configurations for binaries utilized by ArchiDroid's Init.
ArchiDroid's HArdware Volatile Entropy Gathering and Expansion Daemon (Haveged)
The haveged project is an attempt to provide an easy-to-use, unpredictable random number generator based upon an adaptation of the HAVEGE algorithm. Haveged was created to remedy low-entropy conditions in the Linux random device that can occur under some workloads, especially on headless servers. Current development of haveged is directed towards improving overall reliablity and adaptability while minimizing the barriers to using haveged for other tasks.
The original HAVEGE research dates back to 2003 and much of the original haveged documentation is now quite dated. Recent work on haveged has included an effort to provide more recent information on the project and its applications.
The original research behind HAVEGE use was based upon studies of the behavior of processor caches from a hardware level. The 'Flutter' documents attempt to provide a modern view of HAVEGE at software level through the use of a diagnostic build of haveged that captures the non deterministic inputs to haveged for analysis by external tools.
ArchiDroid has built-in haveged entropy generator. It's controlable through ArchiDroid's Backend Control - ArchiDroid_Haveged_EnableDisable.sh. It's turned on in default configuration, through HAVEGED_ENABLED
ArchiDroid's Fast Random Number Generator (Frandom)
Frandom is a Linux kernel random number generator, which is 10-50 times faster than what you get from Linux' built-in /dev/urandom. And it uses very little (/dev/frandom) or none (/dev/erandom) of the kernel's entropy pool, so it is very useful for applications that require a handy source for lots of random data.
ArchiDroid has built-in frandom activator. It's controlable through ArchiDroid's Backend Control - ArchiDroid_Frandom_EnableDisable.sh. It's turned on in default configuration, through FRANDOM_ENABLED.
Notice: Kernel must support frandom module to actually make use of that. Init will try to search for frandom.ko module and load it, then use /dev/erandom for both /dev/random and /dev/urandom. If your kernel supports frandom, it will work. If it doesn't, obviously this will be skipped even if you have FRANDOM_ENABLED. Check ArchiDroid Init log located in /data/media/0/ArchiDroid/Init.log to check if frandom works properly for you.
ArchiDroid's Adblock (dnsmasq/dnrd, dnsproxy2, pixelserv)
dnsproxy2 is a replacement DNS proxy for Android 4.3+
This currently allows the user to manually override the DNS server IP,
and it sets the correct UID on outbound requests so they can be filtered
via iptables / AFWall+ / DroidWall / etc.
Dnsmasq is a lightweight server designed to provide DNS, DHCP and TFTP services to a small-scale network. It can serve the names of local machines which are not in the global DNS. The DHCP server integrates with the DNS server and allows machines with DHCP-allocated addresses to appear in the DNS with names configured either in each host or in a central configuration file. Dnsmasq supports static and dynamic DHCP leases and BOOTP for network booting of diskless machines.
Dnrd, Domain Name Relay Daemon is a caching, forwarding DNS proxy server. Most useful on vpn or dialup firewalls but it is also a nice DNS cache for minor networks and workstations.
Pixelserv is a super minimal webserver, it's one and only purpose is serving a 1x1 pixel transparent gif file. Using some creative firewalling (netfilter/iptables) rules you can redirect some webrequests (for adds for example) to pixelserv.
ArchiDroid has built-in Adblock. It's controlable through ArchiDroid's Backend Control:
ArchiDroid_Adblock_DnsmasqDnrdModeSwitch.sh
ArchiDroid_Adblock_EnableDisable.sh
ArchiDroid_Adblock_EnableDisableLocalDNSes.sh
ArchiDroid_Adblock_EnableDisableLocalDNSesDaemon.sh
ArchiDroid_Adblock_LockUnlockHosts.sh
ArchiDroid_Adblock_MoabAdawayHostsSwitch.sh
ArchiDroid_Adblock_Reload.sh
It's turned on in default configuration, through:
ADBLOCK_ENABLED
ADBLOCK_LOCAL_DNSES_DAEMON_ENABLED
ADBLOCK_LOCAL_DNSES_ENABLED
ADBLOCK_USE_ADAWAY_HOSTS
ADBLOCK_USE_DNSMASQ
In short. This is a very advanced and powerful solution for blocking ads through DNS queries. First of all we're forwarding all DNS traffic to localhost (127.0.0.1). Then we're handling them through local DNS server - dnsmasq (default), or dnrd (option). Our local DNS server reads blocked hostnames through special /system/archidroid/etc/hosts file, then if no record is found, it forwards DNS query to OpenDNS/Google DNS servers, or if it's found, returns 127.0.0.1 as the address. Lastly, pixelserv is providing a 1x1 NULLGIF response on local web server, so instead of big black/white screen instead of the AD, we get 1x1 transparent pixel, which usually perfectly hides ad from the app or the website.
Extra features:
1. You can specify if you want to use dnsmasq (default), or dnrd (option) as a local dns server. Dnsmasq is more flexible, modern, faster and has less memory footprint, however I also left dnrd as an option, because it's proven to work stable.
2. You can specify hosts file, which you want to use. In default configuration we use AdAway's hosts file, with more than 30 thousand of records, which results in extra ~2.5 MB memory usage. You have also an option to use MOAB (Mother Of Ad Blocking) hosts file, with more than 330 thousand of records, which will result in about ~30 MB memory usage. Eventually you can append your own rules or use non-standard hosts file, available in /system/archidroid/etc/hosts. Pro tip: You can point AdAway to use this hosts file (/system/archidroid/etc/hosts_adaway), which will result in automatic updates. /system/archidroid/etc/hosts is a symbolic link, either to hosts_away or hosts_moab, if you want to specify your own hosts, you can delete symbolic link and write your own rules.
3. Original /system/etc/hosts file has been locked from editing. This is to ensure that AdAway or other adblockers won't use obsolete and slow method of blocking ads through hosts. The whole point of implementing Adblock in ArchiDroid is to provide you with super-fast, flexible and effective way of blocking ads, also with getting rid of black/white ad screen. In 99% situations you don't want to touch ArchiDroid's default behaviour, as it blocks ads perfectly. Eventually, if you have a very good reason, you can unlock original hosts file through ArchiDroid's Backend Control and modify them, however keep in mind that every additional rule WILL slow down your network speed.
4. In default configuration local dns server uses two OpenDNS servers at port 5353, two Google DNS servers at port 53 and up to two local DNS servers provided by your Wi-Fi/3G connection, which overall gives a sum of 6 remote dns servers. In some rare scenarios (f.e. some wi-fi hotspots) you can notice that a moron, administrator of this wi-fi, blocked all dns queries and forces you to use his DNSes. This is BAD because of freedom and so on, but it's very common practice, that's why I turned on local DNSes as well. If you want to improve your privacy at least a bit, you can disable local DNS servers and then use only OpenDNS and Google DNS.
5. Above option initialy has been written to allow you one-time access to such non-trusty wi-fi's. But if you for any reason need automatic update of your local DNSes (3G and Wi-Fi's will use different local DNSes), you can also turn on Local DNSes Daemon, which will automatically query and update local DNSes if needed. This is also turned on in addition to local dnses above, of course in default preset.
ArchiDroid's Forced Update (RunOnce)
Forced update selected during mode selection in aroma tells RunOnce to work in "INSTALL" mode even on "UPDATE" mode, apart from that it works exactly the same as update mode, only RunOnce is affected.

C++ Compiler for Android?

After googling this topic and finding nothing, I figured XDA was the place to go. I am looking for a way to get a C++ compiler working on my phone (mytouch slide) or android in general.
Thanks in advance
Que? Like a C++ compiler to compile for android? Why would u want this C++ don't run native on Android it must be called from java so it would be pointless.
There is an sdl port around that required zero knowledge of.java but I believe it still has to compile the java each time. If not it could be possible...
Sent from my Nexus One
I don't want to run the programs on my phone, just compile
Compile for what?
What is the Android NDK?
The Android NDK is a toolset that lets you embed components that make use of native code in your Android applications.
Android applications run in the Dalvik virtual machine. The NDK allows you to implement parts of your applications using native-code languages such as C and C++. This can provide benefits to certain classes of applications, in the form of reuse of existing code and in some cases increased speed.
The NDK provides:
* A set of tools and build files used to generate native code libraries from C and C++ sources
* A way to embed the corresponding native libraries into an application package file (.apk) that can be deployed on Android devices
* A set of native system headers and libraries that will be supported in all future versions of the Android platform, starting from Android 1.5
* Documentation, samples, and tutorials
The latest release of the NDK supports these ARM instruction sets:
* ARMv5TE (including Thumb-1 instructions)
* ARMv7-A (including Thumb-2 and VFPv3-D16 instructions, with optional support for NEON/VFPv3-D32 instructions)
Future releases of the NDK will also support:
* x86 instructions (see CPU-ARCH-ABIS.TXT for more information)
ARMv5TE machine code will run on all ARM-based Android devices. ARMv7-A will run only on devices such as the Verizon Droid or Google Nexus One that have a compatible CPU. The main difference between the two instruction sets is that ARMv7-A supports hardware FPU, Thumb-2, and NEON instructions. You can target either or both of the instruction sets — ARMv5TE is the default, but switching to ARMv7-A is as easy as adding a single line to the application's Application.mk file, without needing to change anything else in the file. You can also build for both architectures at the same time and have everything stored in the final .apk. For complete information is provided in the CPU-ARCH-ABIS.TXT in the NDK package.
The NDK provides stable headers for libc (the C library), libm (the Math library), OpenGL ES (3D graphics library), the JNI interface, and other libraries, as listed in the section below.
The NDK will not benefit most applications. As a developer, you will need to balance its benefits against its drawbacks; notably, using native code does not result in an automatic performance increase, but does always increase application complexity. Typical good candidates for the NDK are self-contained, CPU-intensive operations that don't allocate much memory, such as signal processing, physics simulation, and so on. Simply re-coding a method to run in C usually does not result in a large performance increase. The NDK can, however, can be an effective way to reuse a large corpus of existing C/C++ code.
Please note that the NDK does not enable you to develop native-only applications. Android's primary runtime remains the Dalvik virtual machine.
The ndk allows u to use c++ c/c++ code in Android. That code must be called from java tho.
Sent from my Nexus One
I don't think you guys are understanding his question... He's not looking to write apps for Android... he's writing stuff in C++ (presumably for desktop or maybe other embedded applications, I dunno) and just wants to be able to compile that code on his Android device...
Now as far as an answer to that question, they did kinda cover it... Since pretty much everything in Android runs in Java, I believe it would be pretty difficult to write a C++ compiler that could run on Android.
To install an compiler in your Android device, google around for how to install Debian in it. Don't be afraid, you install it in parallel of Android, you will need a command or terminal window as well (available in the marketplace).
Debian comes with everything you need to compile in your device.
I hope I was useful.
Cheers
Thank you abrigham for clearing that up for me. You are exactly correct.
Ernestus, that seems like it would cause more problems then it would be worth
hmm.. i was googling for this as well.. thought it'll be useful to have this around.

Next best option then is to cross-compile to Android/ARM from another platform. The arm-eabi toolchain provided by Google's NDK is one option as others have already mentioned.
Codesourcery ARM toolchain is another, for Linux i686 theres link to the downloadable archive see this post (search for 'wget THISLINK' text on that page).

If your looking to corss compile for android, check this link out.
http://teslacoilsw.com/dropbear
Installing debian isn't too bad, and would give you the most flexibility for compiling on the phone.
You could also ssh into another computer using connectbot or some other terminal and code/compile remotely.
Another way to do remote compiles is continuous integration. Edit/upload the file to your repository, and using a server such as Jenkins, run the compile and view the results through the browser or an app such as Hudson2Go. Jenkins will also auto-compile on edits and can send you a text if the build fails. Jenkins is very easy to setup.
Try finding an online c++ compiler or you could connect to a windows or linux machine/server to upload andcompile your c++ files.

Use "c4droid" this is a paid app.. anywy if you like search on the market.
Another alternitiv is out there now. Not sure how good it works.
C / C++ Compiler
im looking for compiler too i found i market a4droid compiler but it costs... and i couldnt find enywhere free apk
Easiest thing to do would be a chroot Linux environment from an existing distribution, like Ubuntu. Then compilers for nearly any language you can think of are an "apt-get install" away.
If you're running CyanogenMod 7, you have a large SD card, and you don't mind repartitioning the SD card and shaving off 2 GB or 4 GB for Linux, then I'll be posting a howto in the next day or two. I have Ubuntu 11.10 Oneiric Ocelot running out of /sd-ext cleanly, using only files from official sources (<32 MB file from cdimage.ubuntu.com and everything else via apt/dpkg with signature verification) rather than from rapidshare-like sites.
Or about a year ago there were instructions posted for unzipping a ~2 GB image containing an older version of Ubuntu downloaded from a filesharing site. You could do that if you have an immediate need.
you can download from my blog
http://dateno1.egloos.com/855501
it from https://market.android.com/details?id=com.n0n3m4.gcc4droid&feature=more_from_developer
it has some library problem but work well (i already compile few binary for my phone )
I think c4droid maches perfectly what you were looking for. I'm using it to work on my projects "on the road" and so far it works pretty well.
A little tricky to set up, since you need "gcc plugin for c4droid" but to choose g++ compiler, and builds are saved at "data/data/com.n0n2m3.c4droid/files/temp" or something like that...
There's another option, but you still have to pay: DroidEdit Pro. Perhaps better editor (didn't test it though) but without it's own compiler, you have to set up an external compiler from sftp server.

[APP/SKN][Beta][CE 5.0/6.0] ceFFM - A Fingerfriendly Menu (Shell) for Sat Nav's

Today, I present to you the ceFFM application, as a thank you to this forum that has always given me so much. It is a little personal project I am working on when I am not doing anything else. It mainly was suggested by a friend of mine who is not convinced of 'MioPocket' or comparable other shells for Windows® (Embedded) CE based Sat Nav units, this because of their not Windows® Embedded CE 6.0 fair implementation and their immense RAM hunger and/or missing finger-friendliness, as he said.

Abstract:
(i) What is ceFFM?
ceFFM is a free (as in "free speech" and also as in "free beer") absolute finger-friendly shell/menu ( at least I think so ) for Windows® CE (.NET) 5.0 (CE5) and/or Windows® Embedded CE (.NET) 6.0 (CE6) based Sat Nav touchscreen devices with an ARM™ processor equipped board . Hence I titled the project ceFFM. Its skin is based on opensource-ware 'CEMenu'. Its use is governed by GPL License. ceFFM is legal to use, as it consists 100% of freely-distributable content. It is NOT a replacement for any OEM navigation software. It is just a frontend from which you may among other things launch the navigation software that came with your device or that you purchase separately.
(ii) What are ceFFM's main features?
Basically ceFFM acts as an "unlock" for Sat Nav devices (AKA PNAs/AIOs) running either CE5 or CE6. Such devices almost always boot into the manufacturer's software with no way to exit it, meaning that you cannot run any other software; i.e. the device is "locked." Unlocking your device allows you to use it for far more than the manufacturer intended (ex. for music, movies, appointments, other navigation apps, etc.) and more like a PDA. Additionally ceFFM does something your Sat Nav already probably does on its own (launch applications), except that it adds the ability for you to customize your Sat Nav in more ways than you normally can, so that you can launch applications quicker and more easily. For example, ceFFM creates for you up to nine different 'desktops', giving you quick access to more applications than before.
(iii) What types of programs does ceFFM come with?
ceFFM comes with just nearly three dozens of applications recognized by me as usefull. See list "Featured Applications" below. Important: ceFFM does not come with iGo, GarminXT, TomTom, Destinator, Sygic, AutoSputnik, NDrive, Mireo, PolNav or any other commercial navigation software. Icons may be included for them, but not the programs, themselves (since they are not free). Note that ceFFM does NOT replace Microsoft's file-viewers and third-party's flash-player if these are inbuilt by OEM, but uses them.
(iiii) What devices does ceFFM run on?
Technically, ceFFM should run on any CE5 and/or CE6 based touchscreen device with an ARM™ processor equipped board, where unit's touchscreen has landscape orientation. ceFFM is NOT intended to be run on mobile devices based on Windows Mobile 5.0 and/or Windows Mobile 6.x, because those Windows Mobile based units' touchscreen has portrait orientation. ceFFM is not hard-coded to any particular brand or configuration, quite reverse. Note that every CE5 and/or CE6 based device is slightly different, though, and due to the great many brands and configurations that are out there, the ease of installation and the number of applications and features that actually work will vary.
(iiiii) What is ceFFM's memory footprint?
ceFFM respects Windows® (Embedded) CE is made for devices that have minimal memory. Hence it is designed to be resource-friendly. Its CPU and memory usage are low (ex. compared with MioPocket 4.0 Rel. 68 only scarcely an eighth).
(iiiiii) Does ceFFM install to SD/MMC/CF-card or to internal flash disk (Card-free)?
Both. You have the option of either. But recommended of course is flash disk installation (a certain gain in speed one may notice). Note: Current SD/MMC/CF-cards have more performance than internal memory anyway, the tradeoff is that you must either have a single card which is NEVER removed, or take care before removing it, be sure programs installed there are not running if you have to swap it out.
(iiiiiii) Can ceFFM brick my device?
In principle, from the concept, NO. It really does not hurt anything, it is considered to be exceptionally safe. This due to the fact ceFFM simply overlays device's default shell/menu which you re-gain access to if you exit ceFFM. The changes to CE's registry made by ceFFM affect unit's registry keys as following
[HKCU\SOFTWARE\ceFFM]

URL
InstallFolderPath
Version
[HKLM\init]
Launch253
Depend253
Launch255
Depend255
[HKLM\Loader]

(iiiiii) Does ceFFM have multi-lingual support?
NO. It comes only in English.
(iiiiiiii) Which is the programming language ceFFM is based on?
ceFFM is based on 'MortScript 4.3.b.15' , a macro type program (i.e. "hacker tool without a nifty interface").
Screen Shots:
License Agreement:
ceFFM is free software which everyone can use free of charge, redistribute and change under the terms of the General Public License version 2.0 (GPL v2.0).
System Requirements:
a) A working CE5 and/or CE6 based Sat Nav touchscreen device with an ARM™ processor equipped board (compellingly display mode with either 480x272px or 800x480px screen-resolution, this because of ceFFM is designed to work solely in landscape mode with regards of fact that all PNA's/AIO's touchscreen has landscape orientation) with (optional) SD/MMC/CF-card slot and/or at least the possibility to establish an 'ActiveSync' connection with desktop PC / laptop to copy ceFFM to Sat Nav's internal storage device.
b) Library ole32.dll in \Windows (should be there by default)
Safety Notices:
a) Not all OEMs do provide any in-house method of unlocking their device. Any unlocking process for such a device can only come from software hacking sources as ceFFM. If you are afraid of damaging your device or voiding any warranties, do not unlock this device using ceFFM.
b) If your Sat Nav has a 'Password Protected Lock', i.e. a bootup password is set, remove this lock before installing ceFFM. The reason for this is that the password entry box appears off screen and you will have no way to enter the password any more if device became unlocked.
c) In case you decide to install ceFFM on SD/MMC/CF-card do NOT plug in your USB cable until ceFFM has installed and reset the device (otherwise, your SD/MMC/CF-card will dismount and ceFFM will not be able to access it during install).
d) These are the steps you in any case always first of all should do
1. Make sure you calibrate Sat Nav's screen.
2. In case you decide to install ceFFM on SD/MMC/CF-card that came with the Sat Nav, make a backup of the SD/MMC/CF-card before you use it.
IMHO it also is strongly recommended you have (before installing ceFFM) at least these four freeware utilities present at your destop PC / laptop, which allow you to manage your Sat Nav via a working 'ActiveSync' connection
a) CeRegEditor - registry editor.
b) CeRunApp - tool to remotely start an application (incl. copying it) on your Sat Nav from your desktop.
c) CeNotepad - a remote Windows CE text editor (a "Notepad" that can open text files on a connected device directly on the desktop).
d) CeRhost - the counterpart to CE's cerdisp
These utilities for your convenience I have packed into archive ceFFM-Win32-Tools. Link is provided below.
Installation:
Unpacked ceFFM needs ~200 MB free disk space.
1. Switch Sat Nav's USB-mode to 'Serial_Class' (AKA 'ActiveSync' mode)
2. Download and unpack the zip-archive ceFFM-X.X.X to your desktop PC/laptop (Do not extract it directly to your SD/MMC/CF-card, as that often produces errors or corrupted files). Hint: Use a download manager to be sure the download goes errorfree.
3. In unpacked folder ceFFM-X.X.X edit configuration file 'ceFFM.ini' according to your needs
4. Copy unpacked folder ceFFM-X.X.X somewhere to your Sat Nav's internal and/or external flashdrive - highest reommended of course there into the root ("<storage device>"). Owners of a Magellan may copy unpacked folder ceFFM-X.X.X to "\HDD\APP", owners of a Pioneer Avic may copy unpacked folder ceFFM-X.X.X to "\My Flash\APL2", owners of a YF International (Yuan Feng) may copy unpacked folder ceFFM-X.X.X to "\ResidentFlash2\YFAP30", etc.pp, there are no restrictions. Be warned: Copying unpacked ceFFM via 'ActiveSync' to Sat Nav's internal flash drive takes approx. 0.75 hours.
5. Ensure your device's battery is charged as 100% and/or the Sat Nav has a working external power supply. Note that ceFFM refuses its installation in case no external power supply is given if battery is charged less than 30% - reason: on some Sat Nav's you can watch the battery gauge go down 1% for every 10 seconds.
6. Finally on your Sat Nav run in folder "<storage device>\ceFFM-X.X.X" executable 'ceFFM.exe'. Hint: A lot of the current PNAs/AIOs have a real simple kludge for this. In the 'Settings' section there is a 'Choose navigation program path' option. You use this to point to 'ceFFM.exe' and run it. Also with many CE devices that I have come across, a script named 'shell.ini' does that. If 'shell.ini' is in root SD/MMC/CF-card, the script will be executed when you press navigation on the original screen menu. If 'shell.ini' is in Sat Nav's resident storage memory (ex. \ResidentFlash), and there is no SD/MMC/CF-card inserted, the script will be executed automatically on device power on. Note that the 'shell.ini' in root of SD/MMC/CF-card has priority over 'shell.ini' in resident flash memory. To start ceFFM contents of 'shell.ini' may look like \SDMMC\ceFFM-X.X.X\ceFFM.exe. Alternatively, if you can establish an 'ActiveSync' connection, you might use utility 'CeRunApp' from ceFFM's Win32-Tools mentioned above to remotely run 'ceFFM.exe' on SD/MMC/CF-card plugged in to Sat Nav device.
You should know that if OS's registry is of type file-based (as with most current CE6 devices) and if ceFFM runs for the first time and in ceFFM's configuration file 'ceFFM.ini' key 'BackupSystem' is set to 1, then a complete backup of Sat Nav's registry is made.
If ceFFM is successfully run for the first time, it registers itself in unit's registry as key HKEY_CURRENT_USER\Software\ceFFM; i.e. these entries are created:
[HKCU\SOFTWARE\ceFFM]
InstallFolderPath
LaunchCount
ResidentFolderPath
URL
Version
Click to expand...
Click to collapse
Also, if in ceFFM's configuration file 'ceFFM.ini' key 'AutoStartCeFFMAtBootTime' is set to 1, ceFFM attempts to add itself to device's registry in HKEY_LOCAL_MACHINE\init key as the last startup application possible, thus it is started automatically when device boots, in registry these four entries additionally are created:
[HKLM\init]
Launch253
Depend253
Launch255
Depend255
Click to expand...
Click to collapse
And, if ceFFM is installed on SD/MMC/CF-card, and if its 'AutoStartCeFFMAtBootTime' option is chosen, additionally in device's internal flashdrive a new folder ceFFM-X.X.X with size of max. 1.5 MB - depends on CE's version, will be created, which hosts a few files.
Depending on the amount of options enabled, installation may take 10 minutes.
During ceFFM's first installation the content of some its folders/files gets heavily changed, i.e. directories get removed, files' content get changed, .ZIP-files get extracted and then removed, etc.pp. So you only can use the pre-first-time-installation copy of ceFFM for another installation.
Notes:
a) If your device does not have an SD/MMC/CF-card slot, you probably need 'Microsoft Windows Mobile Device Center Driver' (AKA 'ActiveSync'). It is available for Windows Vista / 7 both 32-bit and 64-bit. You get this driver here:
64-bit: drvupdate-amd64.exe
32-bit: drvupdate-x86.exe
b) The best way to format your SD/MMC memory card is using SD formatter 3.1. At time of this writing this is the latest version of SD formatter which specifically designed to format SD/SDHC/SDXC memory cards. This is absolutely better than using your default operating system format utilities.
c) If installed to SD/MMC/CF-card, do not remove the SD/MMC/CF-card when ceFFM is open, or its folders/files may be damaged or the system may crash.
Updating/upgrading:
See above under Installation. Note that ceFFM tries to detect an earlier-version installation and if detected, deletes all non conformant folders/files created by the earlier version before installing the update/upgrade ceFFM-X.X.X takes place.
Customizing:
ceFFM is steered by its configuration file 'ceFFM.ini'. ceFFM reads this file each time it runs, hence you can change at any time ceFFM's run-options. If an option got changed, ceFFM re-configures itself (and system) on-the-fly.
Uninstallation:
In ceFFM's configuration file 'ceFFM.ini' simply set Uninstall to 1 and re-run ceFFM. This will completely remove the existing installation.
Note that versions prior to 0.3.0 have no explicit uninstall mechanism/routine. You simply delete folder ceFMM-X.X.X on Sat Nav's drive it was installed on. In case of a hive-based registry you additionally manually by means of a registry editor remove entries
[HKLM\init]

if these are present, otherwise you simply hard-reset the Sat Nav unit. Important note concerning Sat Nav units with file-based registries: Changes made to Sat Nav's registry by a bundled application, means if such one was started from within ceFFM's skin, will NOT be undone, because this would be an impossible venture.
Depending on the amount of options enabled, uninstallation may take 5 minutes.

None of these applications requires Microsoft .NET CF and/or OpenNETCF SDF, they all are written and compiled as native, not as managed code! Furthermore, none of the files is compressed (AKA 'UPXed'). Note that this assembly only is a personal proposal (these applications are the ones I like most). You might change it at any time. An additional set of applications that run well under both CE5 and CE6 I have compiled as ceFFM-Extensions, link is provided below.
Modifying Skin:
ceFFM does not know of any sophisticated programmatical skin changer/manager, means you must manually edit the appropriate skin-files by yourself. This because of ceFFM is intended to be most simplistic as possible. Sorry for this. But it should be an easy, at least I think so. All skin related stuff is stored in XML based data format. The files concerned are: all in folder '<install drive>\ceFFM-X.X.X' with extension '.cemenu' (except file 'dummy.cemenu' which you never should touch) and all shortcuts in '<install drive>\ceFFM-X.X.X\programs' with extension '.lnk'. Please read file 'CeMenu-ReadMe' for more information.

Virus Information:
You get a warning from your antivirus software during downloading and unpacking ceFFM?
1. Ensure you have the original files
The ceFFM files do not contain any virus or other "add-on" when they are build. The Mediafire servers used for the distribution are known to be reliable, they are used without problem by thousands of software. Against you must be careful if you have downloaded ceFFM on another site not authorized by me. To be sure that ceFFM zip-file has not been modified by a third party you can check the md5sum with the md5sum notice shown above besides the download link.
If you need a MD5 Checksum calculator, I recommend small freeware MD5 Checksum Calculator 0.1.7.138.
2. False detection
The detection of a virus in a file is not an exact science. It may happen that the antivirus software find a resemblance to a known virus and gives an alert.
Feedback:
ceFFM is still a work in progress. Feel free to report bugs, make improvement suggestions, etc.pp. It would also help that when you write about problems, to tell me what device are you using and what CE version it is running. Be precise! Describe the problem in as much detail as possible. I will not be bothered to answer posts such as "it don't work for me, help!".

Prudent ones might install and use WinCE 5.0/6.0 Device Emulator on their desktop PC / laptop to try out ceFFM before installing ceFFM to their Sat Nav.
I know, posting on my own post... but I just edited the original post and wanted to make sure it got brought forward...
Change Log ceFFM 0.1.1 (800x480px):
1) squeezed images used, hence shorter load time, less RAM-usage
2) added a launcher/installer routine
3) added a "RestoreToFactoryDefaults" icon/routine (Warning: DO NOT RUN THIS, IF YOU DON'T KNOW WHAT MAY HAPPEN!)
4) added some (useful ?) applications
Change Log ceFFM 0.2.0:
Now both 480x272 and 800x480 ready.
Change Log ceFFM 0.2.1:
Two bugs fixed. Thanks to joshli.
Download newest version: See post#1
Good to see a descent menu for WinCE6 Sat Nav devices, since they starting to be big part of the GPS devices that sold nowadays.
jwoegerbauer said:
This due to the fact ceFFM simply overlays device's default shell/menu which you re-gain access to if you exit ceFFM.

Is this means that the Registry Init keys first launch the original nav program, and only then ceFFM? Isn't that a little memory consuming?
A little suggestion:
Add the Installation and Uninstallation part to the readme file. They're kind of must-be over there.
TY for this shell!!

Should be no problem. Most CE6 AIOs present a start menu (i.e. shell), do not immediately start any application (ex. navigation program) per se. This initial menu usually has only a few KB, so this is certainly negligible.

Added to the TODO list! Thanks for the hint.
Positive or negative criticism please
There have been 95 downloads but only 2 responses here after it has been applied to devices. Could someone let me know if he/she likes it on his/her device or not, how to improve it or what? I am willing to spend further efforts into this project, publish in the near future a final version here ...
I just found out about this today, I will try it on jvc NT3HDT.
Is there any kind of precaution i should be aware of before running it.
Also do you have any script that can back up/dump NAV original software before any tweaking?
Thanks

ceFFM doesn't hurt any thing. Promised. ceFFM simply waits default start-up has finished, then it presents to you an extra shell which you like, or not. If you exit ceFFM you are returned to your JVC's default shell.
Also do you have any script that can back up/dump NAV original software before any tweaking?

Your unit's original software isn't affected at all. Hence there isn't the need to backup anything. But of course you can backup the JVC's registry by means of CeRegEditor or any other tool, if you can establish a so-called ActiveSync-connection between your JVC and desktop PC/Laptop.
No Luck
HeadUnit bypassed the sd card completely and booted into the oem nav software.
Let me know if you have something else i can throught at the HU.
ceFFM needs to be manually installed, no auto-installation feature given

If you can establish a so-called ActiveSync-connection between your JVC and desktop PC/Laptop ( of course USB-cable is necessary ), then you can start ceFFM.exe on the SD-card inserted manually, using herefore a Win32 freeware tool as for example "EveryWAN Personal Edition" or "My Mobiler", or any other tool you like.
I will research Activesync and see if my HU can establish that connection.
I might need to pick up a M-M usb cable from the store.
Thanks again jwoegerbauer for the reply. it was worth a try...
Hi jwoegerbauer, I have just downloaded and when I can I´ll try to install on my Chiness GPS with Windows Embedded 6.0, and I´ll post here the result. Thanks.
Great Program
I just downloaded and installed the program today on my chinese double din car unit, this is a really awesome program.
I have one small question.
Is there a way to change the path of the IGO icon to point to my navigation software?
Right now I have to exit ceFFM and then change the path in Wince to boot into IGO.
Thanks
Changing path to an external app
The path to an external application as this is the case with iGO too is defined in a related shortcut-file to be found in <installdrive>\ceFFM\programs. Please modify there the path.
For your convenience you might use Win32 freeware CeNotepad - ActiveSync connection required.
Adding new icons
I have tested it and it works ok. It is very friendly and have e very good aspect. Very good job. Thanks.
I have a question, is there any way to add new icons to an extrenal application?.

Of course.
1) Adding: You simply add to
a) folder <installdrive>\ceFFM\icons\extern an icon you created - a template is to be found in folder <installdrive>\ceFFM\icons (BlankSR.png)
b) folder <installdrive>\ceFFM\programs a shortcut-file to the external application, you might create with Win32 freeware nueShortcutMaker - ActiveSync connection recommended
c) the menu's page you want to extend (ex. Favorites => script-file <installdrive>\ceFFM\favorites.cmenu) an additional entry like this
Code:
<Button img="icons\extern\QuranSR.png" action="programs\PocketIslam.lnk" params="" />
2) Deleting: basically same logic as Adding an icon, but simply reverse.
I figured it out

Because ceFFM is installed on a SD card in my car unit, I was able to bring the card in the house and use my desktop to make the changes.
It took me a few trys but I figured it out.
I deleted your icon in the programs folder and created a new one with the correct path using nueShortcutMaker.
Everything works fine now
Thanks for your help.
Starting / Killing applications before ceFFM starts
A feature not evident at first glance. How to activate it?
ceFMM gets started via "<flashdrive>\ceFFMLaunch.exe" ( simply a renamed TULL.exe - by Dack ) which reads an .INI-file to find out what commands to perform. This .INI-file is the place you can stop and/or start applications prior ceFFM gets started. For example
1) to start the RAM-cleaner that comes with ceFFM, you would add to "<flashdrive>\ceFFMLaunch.ini" a line such as
Code:
W "\NandFlash\ceFFM\program files\ce-utils\RAM Sweeper\RAMSweeper.exe"
2) to stop AppXXX that runs by default on your Sat Nav, but you think it is senseless to have this application running (which besides is RAM and CPU wasting), you would add to "<flashdrive>\ceFFMLaunch.ini" a line such as
Code:
Z AppXXX.exe
Important: NEVER KILL SAT NAV's DEFAULT SHELL, this because if exiting ceFFM you land in the nirwana. IMO a good candidate for killing is "DW.exe" (Dr.Watson watchdog application) which is present at many CE 6.0 based units.
the most important app for our devices ;-)

Wow, I have been looking for something like this for last 2 weeks, hope it works with my new Innovatek72 gps that is on its way, can`t wait to get it all installed and running

Hi All,
Before my ideas with init hijack, and uboot hijack, I had a idea with trying to implement a kernel module to allow execution of any code, after killing linux without a full reboot (which would give control back to secure boot). However 2ndihkvc and NOPBypass came in between this.
However I will try and put sometime into it, as and when possible. I have some work coming up over the next few days, so going will be bit slow compared to my other two threads, but if nothing turns up from BN side (what I heard from Adamoutler on the other thread) wrt open ended bootloader then I will spend bit time on this.
Note that one doesn't require kexec to achieve functionality similar to kexec ;-). Linux kernel modules is a very powerfull mechanism which we have in our hand to give lot of or all the control required (Unless linux has changed drastically over the last few years, when I have been away from it, but that seems less likely, even thou I have heard and discussed some ideas which curtail this power almost a decade back, but I don't think it has materialised yet, which should be good for the situation we are in, and hope it remains like that for the forseeable future, what with all these close minded companies and closed devices these days).
NOTE: Look to the newer posts below for the Source Codes. RC1 source code in a day or two (but has mentioned, no significant changes wrt Beta
[REPOST] MAYBE Exec_Anycode instead of kexec
>>>> This was my old post on bypass bootloader ideas thread, put here for completeness <<<<
*** MAY BE A POSSIBLE EXEC_ANYCODE logic instead of KEXEC***
NOTE: KEXEC tries to run another linux kernel, so may be its logic is more complicated, than if we are trying to run just any code in kernel or better privilage level. I haven't looked into kexec as of now, so I am only guessing about kexec complexity, beyond what I have mentioned below for my method (which again I haven't tried as of now, just a idea).
If one is trying to run something from memory when already in Linux, then one also has to worry about the privilage level at which the processor is running, as well as about page table mapping etc... If the other thing which we are trying to run is another kernel or x-loader or uboot or another bootloader for that matter.
So if kexec doesn't work, may be there is another option available which is to
a) Create a kernel module (NOTE: It runs with same privilages as the kernel) which does
a.1) Disable interrupts so that control doesn't get out of our code
a.2) Over write the reset vector with x-loader or what ever custom bootloader one wants to get control of.
a.3) Change the memory map to have a 1-to-1 map for the region where the code is currently running (or rather for the code which will be run in the next step) or overwrite a region which already has 1-to-1 map between Physical and Virtual addresses, with the code for the next steps. Go to next step.
a.4) Disable page tables (I haven't tried this before, ie after it has already been enabled, but I don't see any reason why ARM doesn't allow this - except for things like what we are trying).
a.5) Change to the reset ARM privilage level (If a soft reset doesn't do it already, haven't looked at ARM at this level for ages, so don't remember)
a.6) Trigger a soft reset
This should give control to the bootloader which we have loaded into the reset vector address. (Rather we should trap all possible exceptions i.e all the 8 or 16 or what ever is the number of exception addresses in the exception vector).
NOTE: If we are not able to change back to the reset time privilage level for the ARM processor, then we should be still able to have a modified Linux kernel, which doesn't try to switch ARM privilages if not required - this I have tried, ages ago, If I am not wrong as part of some other activity I had done.
Current thoughts
Hi,
On thinking once again
a) We definately want to disable interrupts, so that we don't lose control other than for exceptions if at all.
b) We may have to stop the other processor if it is up in SMP, but I have noticed that most of the time, the other processor is shutdown in NookTab.(Have to think thro this bit more, later).
c) May be trap the TLB exception handler and inject custom pagetable till MMU is switched off (An idea for now, have to experiment a bit later). Rather than going thro the linux mmu code (am getting bit old, a decade back I would have done the required linux magic in few jiffies, but have been away from linux for too long now . OR force few entries into current/kernel linux memory map.
d) Copy
d.1) the core code required to manage stuff to a 1:1 mapped region.
d.2) Also the code required to jump to like (i.e the bootloader or what ever)
Other d.2) Or implement minimal code (as part of d.1) to read uart (oops - now that would have cut the complexity by 3/4th, but for people hating uart these days;-) or may be sd card and get a sector into memory (like x-loader).
e) Disable the mmu
f) Jump to the required code location of new universe
Today I did a quick running/jumping glance thro kexec code once, and even it does some what similar only, if I am not wrong, except for may be it not hijacking the TLB exception handler or having some junk for debugging or so ..., so I am not that off wrt the required idea.
First baby step - try and understand the default memory map
Hi,
Did try the 1st baby step towards this, by trying to go thro the running systems memory map.
LBHKVC driver v04Jan2012_2110
INFO: Total memory is iTotalMem 0x40000000
INFO: Page Size ??? PAGE_SHIFT 12 ie 4096
INFO: Begining of Platform ram PHYS_OFFSET 0x80000000(0x40000000)
INFO: End of userspace mapping TASK_SIZE 0xbf000000(0x7f000000)
INFO: Start address for Modules Space MODULES_VADDR 0xbf000000(0x7f000000)
INFO: End address for Modules Space MODULES_END 0xbfe00000(0x7fe00000)
INFO: Permanent kernal mappings PKMAP_BASE 0xbfe00000(0x7fe00000)
INFO: Kernel direct 1:1 map ??? platform RamBeg PAGE_OFFSET 0xc0000000(0x80000000)
INFO: Kernel direct 1:1 map ??? platform RamEnd high_memory 0xf0000000(0xb0000000)

INFO: vmalloc/ioremap space End VMALLOC_END 0xf8000000(0xb8000000)
Now one thing which is potentially true and easy is, the Physical Memory from 0x8000.0000 is 1:1 mapped to 0xc000.0000 in a linear way (Have to validate, but should be). There are certain virtual to physical maps which seem bit odd, most probably I am using the wrong function to do the conversion and or traversal of pagetable. Also some of them are not necessarily meant to have a mapping other than act has markers conceptually (Have to verify later).
Having something same to same mapped would have kept things to a minimal, and made this too trivial now - why not ooh linux gods ;-(. Now this is forcing some hijacking or forcing of page table entries or experimenting and seeing if this is good enough to me/any one else interested.
Also there seems to be something called SAR_RAM, have to see if this is of any use. As well as some of the regions reserved thro kernel command line and see if anyone is using it, or if it can be evicted if required, there are only for funny experimentations.
Otherwise I think, I should be able to get even my current modules virtual address translated to physical address and may be same-to-same mapped if required. Or forcefully take some region beyond my current running code and any exception logic I require.
Also I have to check how critical is the same-to-same map if any when switching off mmu, or is 1:1 map good enough, have been away from lowlevel arm also for too long now.
Wow hkvc you respond quicker then I do.
First off it is not a 1 to 1 mapping if you look at the arm B&Ndefconfig youll see that they utilize a different way of mapping (not looking at the code right now).
Second off kexec with the kernel module that does KEXEC_LOADED is essentially this. I would look at the kexec.c code, and you will see that you can comment out the sanity checks in the find hole function and it will find a valid hole, then with injection you could make this work. However, while i have done embedded design and some hacking, kernel modules are not my specialty. We need a high priority kernel module that removes interrupts, so that the kexec code can load.
baby step2 of linboothkvc
Hi Loglud/All,
Thanks for your inputs.
Not sure about ur (Loglud) 1:1 map part comment. Currenty when people say 1:1 I am not sure whether they mean linear map (i.e with a constant addition or substration you can get virtual - to - physical mapping and inturn the other way round) or same to same mapping, I have to look at arm initial booting code and see what they mean (and in turn what ARM requires), because they require this when booting and inturn the mmu gets enabled.
Also the code to dump the map what I put above, was my first attempt at kernel level view of memory maps after ages, so there are some FUNNY ;-) errors in the way I tried to dump it quick and dirty.
If you are talking about 0xC000.0000 (Virt) to 0x8000.0000 (Phys) mapping which I mentioned, I still feel it is linear mapping, but I have to verify once. Linux kernel used to maintain a linear mapped region to simplify the internal management of physical pages(i.e memory), so that they can convert from virt2phy and back easily wrt physical memory with out requiring to go thro pagetables and for other reasons (Obviously with limits, i.e the Full memory is not linearly mapped but the initial 800MB or 900MB or so used to be). I will verify it later.
Either way independent of that I have potentially found the region which I will be attacking wrt getting the required same-to-same mapping (which I want to use, even if linear map is good enough, which again I am not sure is true at this time). The VIRTUAL ADDRESS space set aside for kernel Modules in Linux (MODULES_VADDR (0xbf00.0000 ...) and MODULES_END) overlaps with the actual physical memory location (0x8000.0000 - 0xc000.0000) here. And there is enough free memory in this module virtual address space, as there are only 2 modules loaded in NookTab, plus the region is originally there to allow lot of modules plus worst case I don't really worry much about stomping_on/reusing someone elses used memory because I am going to kill the system shortly and I have already locked the current cpu by blocking interrupts.
Inturn I will initially see if there is a physical page in the physical address space from 0xbf00.0000 to MODULES_END such that I can do a direct same-to-same mapping into the corresponding Virtual address space. Again even if there is non, at one level I may not have to mind really ;-) as I will be nuking the full system shortly.
I am looking at same-to-same mapping to allow the code which will do the mmu disable to continue to work before and after mmu disabling. While a Linear mapped region is good to load the code (bootloader, kernel, ....), before mmu is switched off, which will be passed control after mmu has been disabled, and which inturn can welcome the new system.
NOTE: I am in this more for the fun of exploring, so at least initially I don't want to use kexec and modify it (If I fail, then I may look at using it directly, but don't see a reason to fail for now), rather I want to come up with a concept (and as you rightly mentioned, even kexec follows (and it definitely should) similar concept to a great extent except for may be some of the implementation steps, as end goals are similar) and then implement it for the fun of it, even in crazy ways if possible (I am just starting out on this now, so I dont want to say one way or the other on this aspect now) just for it
NOTE: I am explaining my thoughts, so if someone else is interested in experimenting parallely on his/her own, they can get some ideas (good or bad
BabyStep3 basic implementation done - but results say long fight ahead
Hi All,
Over yesterday and today, I have implemented a basic logic to test minimal kexec equivalent logic using kernel module.
Rather had to dig thro the kernel source code to
a) refresh thro my kernel basics and to understand atleast some of the changes in the newer kernel versions and MORE importantly
b) to OVER COME the tendency of core kernel developers to DISABLE EXPORT of some of the useful functions to external kernel modules.
Eitherway most of the disabled symbols I could pickup and hardcode the address in my code to still access them indirectly using function pointers - what would world be with out function pointers or rather pointers in general.
Also because of the SMP nature of the SOC, had to dig thro some of those stuffs also. Then for now decided to use some of the support mechanism already available within kernel to help with kexec logic like fin, reset, etc to try and see if I could use the easy path into it for now initially
However what I seem to have realised/found is that
a) Either these support routines haven't been fully implemented in the used kernel version on NookTab currently and or
b) I am missing few more additional steps wrt SMP (Have already killed the 2nd Processor using proper api in kernel - Have to cross check the CP15 to verify for sure once again later).
It seems to be mostly (a) and inturn related to cache cleanup and may be mmu switching, have to debug further.
Otherwise the same logic seems to be working in BeagleboardXM (rather within qemu -M beaglexm) except for some reason the uart messages seem to disappear once I switch over even thou the code seems to be running in the new Same-to-Same map with the physical memory address part, with proper UART address - checked using info registers in qemu (Have to debug this part of qemu related to how it decides which uart to show in Ctl-Alt-3 etc bit more and or try on a physical board sometime next week).
In few days time I will upload the code I have come up with (even thou useless from using/achieving kexec logic perspective currently, still may provide some ideas or act as a base platform for someone wanting to experiment, but having initial inertia , if I am not able to spend more time on it.

Hi All,
As promised, I am uploading the initial version of the kernel module source code (with lot more updates compared to last weekend, when I mentioned about it) for achieving kexec like functionality even if kexec is disabled in kernel. As I always told, kernel modules are equivalent to kernel, so you can do what ever you want in kernel module that can be done in kernel, provided one is bit patient ;-).
Note: This is pre - alpha version of code for people with initial inertia/starting trouble to experiment. This has a known bug with cache handling which I have to fix as well as some restructuring and cleanup to do.
This will currently only run in Qemu, because it doesn't bother much with Cache. But on ACTUAL targets it will fail Randomly (there is a very very small one in a million chance that it can succeed if all the stars line up and the cache gods support you
This is no longer as critical for NookTab has it was 1 week back, because Now some people have already released a exploit which uses a uboot bug ;-(, which ideally we could have with held for a future product (because NookTab was already sufficiently open and didn't need any more exploits to use its full potential, as I had mentioned last week). But either way I realise that people are very impatient these days. And congrats to those people for their work however.
For people who want to experiment, the initial skeleton is available in this release
Alpha release with embedded x-loader for BeagleXM Qemu
Hi,
NOTE: This release successfully bootstraps a new linux from with in linux in Qemu, my yesterdays release would have also done the same, but would have required additional code to handle the final nitty grities, this is taken care of now in this release. So that it is easier for people wanting to experiment.
I have updated the kernel module to allow two images to be embedded into it.
a) The initial boot strap loader called Nirvana (Examples like bloop0.S, bloop1.S, ... and now a full fledged omap3callbootrom1.S for BeagleXM on Qemu - Rather it in itself is independent of Qemu-BeagleXm or Hw-BeagleXM)
and
b) The actual bootloader/???? to run in the new prestine environment called Nirvana's Child (NChild). Currenlty it is a version of the x-loader for BeagleXM (Either Qemu or Actual BeagleXM).
In turn once the kernel module is done with its job. It passes control to Nirvana. Also it passes the physical address and length of the NChild image to Nirvana thro r0 and r1.
The Nirvana code in turn can decide what it wants to do with the system. The default Nirvana code i.e omap3callbootrom1.S takes care of copying the NChild(by default x-load.bin) to 0x4020.0800 and then pass control to 0x4001.4000 so that it loads x-loader properly (ie setup stack for all modes etc).
NOTE: As of now it works on Qemu only. My earlier release yesterday would have just printed 1s on the screen, while this version actually boots into a new linux kernel + system in Qemu from with in a already running Linux system in qemu.
However it won't run outside Qemu successfully, as I haven't yet had time to look at fixing the cache issue, because I had to add support for NChild image logic either way for doing anything useful with the code.
NOTE: As this is either way no longer critical for NookTab, I will take a stab at it based on my hack-vs-life balance also. Depending on what and all come up over the next few days in life.
HOWEVER this latest release has the FULL REQUIRED INFRASTRUCTURE/LOGIC for running this on a actual h/w expect for the missing proper cache handling. It also includes a x-load.bin by default for BeagleXM which can be used either with Qemu-BeagleXm or Hw-BeagleXm.
Beta Source - Success on a Hardware (beaglexm for now) should work on NT also ...
Hi All,
I have finally identified the stupid cache issue which was frustrating me and eating my head for long and stalling this project unnecessarily . However it gave a nice oppurtunity for me to dig thro the kernel code as well as Arm documentations - which is what I am after either way So ALL IS WELL in the end
The problem was related to kernel's normal code using MVA based cache operations for flushing, which in the newer architectures stops mostly at L2 cache rather than hitting the memory. This is fine for Normal linux kernel operations because they don't disable cache and so the proper data will get used. But for us as we want to disable cache to give a true pristine NIRVANA environment, this doesn't work, as memory contains old/stale/wrong data. In our code flow This even affects the KERNEL MODULE CODE itself, leave alone Nirvana or NChild code.
Once I realised this by digging thro documents as well as seeing the strange behaviour (rather unbelieavble, initially for me) of my code(kernel module as well as Nirvana and NChild)/logic after cache disable, I was able to get it RUNNING SUCCESSFULLY on BeagleXM actual hardware and not the qemu emulation which I was previously using.
As of now it is restricted to Omap3/BeagleXM, because the Nirvana code Omap3callbootrom2 makes use of the bootrom memory map usage knowledge to setup NChild appropriately and pass control to it thro Bootrom (so that stack is setup for all modes). With small effort the same can be changed or updated for Omap4 and NT should be in the fold (Unless SMP creeps up, inspite of me shutting down the 2nd processor, for some crazy reason in the worst case ;-)
NOTE: Also my last release (alpha) for Qemu beagle had a bug which was a blessing in disguise, in that it was not disabling the MMU from with in kernel module(which I had added just for the heck of it and is actually not required). However it was still doing it once it hit Nirvana code, as required. If I had not done the mistake of using mrc instead of mcr with in my kernel module code, it would have failed immidiately, because BeagleXM has only 512MB ram and the kernel module code space is at virtual address 0xbf00.0000 or around it, which is WELL BEYOND the 512 MB of physical memory, so there would not have been any 1-to-1 memory map for it and disabling MMU would have made things go crazy. Note that Nirvana and NChild are kmalloced into linear mapped kernel address space which is with in physical memory limits normally ;-).
NOTE: May be there is a watchdog timer or coprocessor or so which I have to disable, haven't looked into this yet, which seems to mess things up, if I stay in Nirvana code for too long. However as by default there is no need to remain in Nirvana code for long, as it is required to pass control to NChild as quickly as possible, this is not a immidiate issue to worry about now.
Let the experimentations begin
For H/w BeagleXM boot, bypass stupid SMI based L2 Cache maintaince rot in uboot ;-)
Hi All,
If anyone has tried running my yesterdays Beta release on BeagleXM h/w there is one update and one other IMPORTANT things to keep in mind.
a) Update the omap3callbootrom2.S to directly call into NChild rather than thro BootRom, that call into BootRom is not required. i.e jump to 0x4020.0800 instead of 0x4001.4000 at the end.
NOTE: This also makes the code more generic and usable with minimal love across Beagle and NookTab.
b) In U-Boot remember to DISABLE/BYPASS the calls to ROM Support routines thro SMI to setup L2 cache as well as to invalidate cache. This is no longer required in newer Omap3 chips as well as there is actually few bugs in u-boot code itself related to this, as one wants to clear full cache but SMI rom routine only clears L2 (also the full cache walking for invalidate is there following the SMI call, so bypassing doesn't lose functionality), if I get rom code description in TRM correctly, plus few other bugs atleast in rowboat version. The files board.c and cache.S contain the calls to SMI which has to be bypassed.
I have attached the minimal patch required to uboot to allow it to work with linboothkvc with BeagleXM.
With the above two changes, linboothkvc will always succeed in BeagleXM, enjoy
NOTE: In my setup today, I have modified the NChild x-loader to load u-bootk.bin rather than u-boot.bin. Thus I can have both the Normal u-boot.bin for Normal booting and u-bootk.bin for linboothkvc based booting . My Beta release doesn't contain this modified x-loader NChild, the next release will contain the modified one. But with source of x-loader, you can do it yourself and copy over as NChild into linboothkvc
Success on nook tab
Hi All,
LinBootHKVC has successfully booted into Nirvana code in NookTab
NOTE: No major change required to my beta release other than one mentioned in my last post to make my released Nirvana code more generic and the address update in this post for NookTab.
As I had mentioned yesterday, even thou I hadn't got the time yesterday to check it on NookTab yet, it should work 90% except for any crazy SMP issues, inspite of me disabling the 2nd Processor. WELL IT turns out that what I had done already was sufficient for NookTab also.
Only in omap3callbootrom2.S you have to change the sram address to which things are copied from 0x4020.0800 to 0x4030.0800 for NChild code. However I haven't crosschecked the x-loader based NChild on NookTab as of now, but DONT SEE ANY REASON why it should fail, other than for any issues with stupid code, like the SMI calls to manage L2 cache in u-boot for beaglexm and for some reason if 0x4030.0000 space has some issues I haven't thought of in Omap4 (I am relatively new to Omap4 started with NookTab only).
Will upload the Release Candidate version 1 of the code in a day or two. It is late here and I have been up on this NookTab project for few weeks now
a) starting from idea of linboothkvc
b) then moving to 2ndihkvc
c) followed by NOPBypass with UART access
0) The uboot loop hole (Oh my my my (But not released from my side hoping to keep it for future, but alas, if only people have/had patience ..., that is partly a dream now
d) followed by MenuK for 2ndihkvc - haven't released yet, time got sucked back
into linboothkvc
and back to
e) linboothkvc
all of the above work on NookTab successfully as of today and all can be used to achieve custom Roms and in case of NOPBypass and linboothkvc even custom kernels
So enjoy everyone. Some sweet rest for me atlast ;-)
NOTE: The POWER of Kernel MODULE and inturn linboothkvc goes well beyond NookTab for the adventures people out there
Oh My MURPHY - For now keep away from 0x4030.xxxx
Hi All,
Now as Murphys law would have it , 0x4030.4350 (the default address used by x-loader in Omap4) has some issue with it (which I have to debug later). So if trying on NookTab remember to use some other address (what other I will leave as a exercise to the interested
Also the x-loader from BN and or inturn from Ti expects a special meta data structure to be passed along thro r0, which inturn tells it about boot device and boot mode. So you will require to take care of this or better still simplify the structure to handle in cpu/omap4/start.S
Also I did the cardinal sin of doing too many changes when working/debugging on a new unknown device (from my perspective i.e NookTab) with no jtag access (atleast at my end for now).
So ended up digging into Arm L2X0 cache and inturn PL310 trm and writing a L2X0 cache flush logic (obviously also cross checking the equivalent logic in Linux kernel) when none was required in reality as I had already found and mentioned in my last post few days back. I forgot (rather got too lazy to checkout my own old code, just for the fun of exploring further ;-) my own Nirvana code which I had tried towards the beginning of the week which had successfully run and printed stuff on screen.
Also dug into the Address translation support registers in CP15 to be 100% sure that the 1-to-1 map was in fact there (again lazy to dig thro the linux kernel setup_mm code, when arm walks the page table tree for you and on top when I had not tried this arm instruction method before .
But ended up finally realizing that me using the 0x4030.4350 was the culprit atleast for now.
So keep away from that address for now (or debug further on this on your own for now, I will be looking at it only later, could be something to do with HS code using that region or ..., there is more interesting stuff to do for now) and remember to patch x-loader appropriately and you should be able to get it running on NookTab; again with my last code release with hardly any changes other than what I have already mentioned in the last 2 to 3 posts.
A updated source with the now useless l2x0 cache flush and va2pa address translation verification logic and a newer nirvana code with panda board support also (verified works perfectly - only slight changes required between Panda and NookTab as far as Nirvana code is concerned) I will release after some more experimentation and code stabilisation at my end.

Thanks for all of your work. Even though the bootloader bypass has been found, you do not know how many others you are helping. This could be used as an indefinite alternative to locked bootloaders for ALL DEVICES! Keep chugging on this, and I'm sure you'll find your solution to the l2 cache flush. Also i have been looking around, and I was curious if this could be another explotable boot flaw,
Code:
/*
* The SAR RAM is maintained during Device OFF mode.
* It is split into 4 banks with different privilege accesses
*
* ---------------------------------------------------------------------
* Access mode Bank Address Range

*/
27.4.4.4.1 Public Use of SAR RAM
At system level, the OMAP4430 SAR RAM memory is divided into four banks. The public ROM code uses only the first bank, which is always public-accessible. More specifically, the software booting configurationstructure must be located in the upper 1.5KB of the first bank.
The public ROM code offers some flexibility about the location of the software booting configuration structure. The PUBLIC_SW_BOOT_CFG_ADDR pointer defines the start address of the structure within the SAR RAM bank (see Table 27-14).
As mentioned previously, the software booting configuration feature is optional. Hence, the public ROM code decides to use the feature based on the value read on a warm reset at the address pointed to by the PUBLIC_SW_BOOT_CFG_ADDR pointer. If the value matches the range 0x4A326A00 – 0x4A326FFF, the ROM code tries to extract the structure located at that address. The value pointed to by PUBLIC_SW_BOOT_CFG_ADDR is always overwritten to zero on a cold reset.
The recommended address for storing the software booting configuration structure described hereafter is defined as PUBLIC_SAR_RAM_1_FREE. It is, however, possible to locate the structure at any location within the 1.5-KB range.
It is moreover possible to use the public SAR RAM area for any other purpose, such as storing traces for HLOS use. Obviously, care must be taken not to overwrite the locations used for low-power modes and/or software booting configuration if used.

linboothkvc v1.0_RC3 with good x-loader for O3Beagle and O4Pandabrd and semi 4NookTab
Hi All,
I am attaching the source code for linboothkvc with a good basic Nirvana code for Omap3 (Many mobiles and few tablets) and Omap4 (few mobiles and tablets) devices. NOTE: for NookTab, basic linboothkvc works perfectly now (except for may be some toning down of the secure Monitor code if possible), However there is some more work required at x-loader (which I am using as my NChild code) level which I have mentioned further below as TODO. Otherwise the basic logic fully works for NookTab also now. At this stage it can be used by developers and not end users as NChild code for NookTab still requires some love.
[A] obviously there would be some minor tweaks to the NChild load address and args to pass etc based on x-loader/bootloader used in a given device, but still the basic skeleton is fully there in Nirvana code now. And the same can be modified for other SOCs from Samsung/NVidia/(Not getting the other vendor name now funny)... pretty easily.
Also the addresses for the linux kernel functions which I use require to be updated for any new device or for a new/different kernel for the devices which I have already put the code in this release.
[C] It expects to find a u-bootk.bin in mmc vfat root dir, provided you are using the x-loader code which I have bundled. How ever based on your device, you may have to change to a different bootloader or modify x-loader to suit that devices need, and thus With your own version of x-loader or NChild code, you can always modify it the way you want as to what it loads and from where.
But with the above changes/setup this can be used with any Rooted ARM based Linux device (be it android or webos or ...)
Changes I had to do to x-loader for NookTab:
[1] I had to bypass or find alternate locations for some of the 0x.4030.xxxx addresses used in x-loader from BN/Ti (Haven't had time to look into the details as to why this is forced on us and how to force the use of the same address yet). For this reason I am recompiling the x-loader with a load address of 0x8000.7ff0 for now and sidestepping it mostly.
[2] Clock and related init settings related to MPU,IVA and DDR memory are offlimits for now (but then again for a basic working these need not be changed at x-loader level eitherway).
[3] smc/SEC_Ppa functions are offlimits for now, again not required at x-loader level.
[4] TODO: the x-loader bundled with BN source seems to be a old version or has some non required (from BN perspective, but usefull from our perspective) logics for BN stripped. So even thou I have modified the high level logic to do a FAT load from MMC for u-bootk.bin. Because of this missing support for FAT boot mode, the current version of x-loader for NookTab which I have bundled in my code doesn't load u-bootk.bin.
Enjoy and happy Experimenting all
NOTE: When I say bundled x-loader, it is only binary blob, you can get the actual source code for x-loader from the respective git sources. I think few days back I uploaded the patch required for beagle x-loader to make it run in linboothkvc Nirvana env. I will do the same for x-loader for NookTab and Omap4 (rather omap4/panda hardly any change required from Ti release - I had to mainly simplify the argument mechanism passed to x-loader and nothing much, if I remember correctly, as I tried pandaboard 1 day back and after that I have done so many other things that, pandaboard is out of my memory Fifo) in few days.
[DONE] source of linboothkvc v1.0 (includes binary for NookTab with working xloader)
Hi All,
LinBootHKVC for NookTab is fully DONE now. Well (for developers) it can work with any ROOTED ARM based LINUX device (android or not doesn't matter) with kernel module support with minimal love, for those who are interested ;-).
Along with the source (which can work with any Arm based linux setup with some minimal love), this release also includes the binary kernel module for BN NOOK TABLET with firmware 1.4.0. Which inturn contains a working x-loader binary as its NChild for NookTab, which looks for a u-bootk.bin file on the uSD card.
To use this on NookTab (similar steps work for any other device, provided you have suitably compiled linboothkvc for your device with proper love)
a) get your required/prefered u-boot.bin file and prepend a 288 (0x120) byte dummy header and name it u-bootk.bin
i.e
dd if=/dev/zero of=/tmp/dummy.bin bs=288 count=1
cat /tmp/dummy.bin u-boot.bin > u-bootk.bin
b) copy this u-bootk.bin to the root directory of the 1st partiton on a uSD card which inturn should be VFAT formated. (To be 100% safe and sure use a newly formated uSD - Or you never know when Murphys law can kick in, see my note at the end for a bad luck I had yesterday night
c) Insert the uSD card to your Nook Tablet
d) Copy to your Rooted NOOK TABLET with firmware 1.4.0 the kernel module lbhkvc_km_DEVICE_NOOKTAB.ko which I have provided with in the release folder in the source package uploaded with this message/post.
__may be__ adb push lbhkvc_km_DEVICE_NOOKTAB.ko /data/local/tmp/
or similar or thro the uSD card and a file manager.
e) either from adb (on PC) or a terminal (on NookTab) or serial port (on PC) get to a root shell.
if using ADB on a PC connected to rooted Nook Tab it will be
adb shell
su
NOTE: PC is NOT required, you can also load the kernel module directly from Nooktab by using a android terminal package to get shell access.
f) insmod the copied Kernel module from the root shell/prompt
insmod lbhkvc_km_DEVICE_NOOKTAB.ko
This will load linboothkvc and inturn do a forced reboot/hijack into a x-loader environment, which will inturn load the u-bootk.bin which you had copied into SD card in steps a to c above.
NOTE: Based on what I have verified, u-boot works with out requiring any change to it (unless you want to bypass the security check in u-boot . So ENJOY.
NOTE: This can equally work on a 1.4.1 firmware based Nook Tablet, provided it is rooted. But for that you will most probably have to recompile my kernel module with updated addresses (if it has changed) for the kernel functions which I am using. However if BN hasn't done any change to kernel in 1.4.1 firmware, then the current kernel module which I have bundled it self will work. I haven't verified with 1.4.1 firmware currently (as I haven't upgraded to 1.4.1)
NOTE: Be sure to save any things you might be working on your NookTab, before loading the kernel module, because it will force a reboot with out any mercy, so any unsaved things in your NookTab can get lost. so BEWARE
NOTE: Rather even yesterdays release would have worked 99%, I had a problem with my uSD card being bit corrupt wrt rootdirectory, which is why it was failing yesterday when I finished it originally . However in this release I have also cleaned up the Nirvana code a small bit to avoid the hardcoded ioremap address of UART.
Release v1.1 source with binary for NookTab
Hi All,
Being bit lazy I had not called cache flush once again after disabling the cache, because I was calling it just a wee bit before disabling it and was also expecting any body who enables Cache in Nirvana environment to do a thorough job of cache invalidation before enabling it again.
However found that the linux kernel 2.6.35 used by Nook firmware has this problem, so now I take care of calling cache disable once again after disabling the Cache to be on safe side and it does help for NookTab (while on Beagle and Pandboard I didn't have this issue, it was a newer kernel which I had tried there so may be it has some additional effort put in wrt cache invalidation or it was pure luck, either way haven't debugged that aspect now).
So with this release, linboothkvc provides a better Nirvana environment, except for the SMC related stuff, which I am ignoring for now . So related to that there is some cleanup or bypassing required to be done in Kernel otherwise linux kernel should be pretty much ok in linboothkvc Nirvana environment, haven't had time to look at it fully yet. Will spend sometime in a day or two when a holiday is coming my way.
Check out the README file some of the same info as above and may be a few more things here and there. Also the new binary for NookTab is there in the source package within the release directory.
I've read every one of these posts and have no idea what is going on but I'm glad that it's all working. Great job!

Getting Linux kernel for NookTab up in LinBootHKVC - Step2 and 3
Hi All,
Step2
------------
There seems to be few race conditions in the linux kernel source and or some initialisations not being done properly in the kernel code, because of which by default the BN kernel source will fail in LinBootHKVC environment.
The below patch fixes 1 such race issue I have noticed wrt initial clock event handler for ipi timer (Have to debug this further later).
NOTE: A initialisation issue with the Cache, in that it not getting invalidated properly during booting was fixed in my v1.1 linboothkvc kernel module, by doing a additional flush before switching to Nirvana. Because that was also a appropriate stuff for linboothkvc also to do, independent of the kernel initialisation issue.
static void ipi_timer(void)
{
struct clock_event_device *evt = &__get_cpu_var(percpu_clockevent);
irq_enter();
- evt->event_handler(evt);
+ if(evt) {
+ if(evt->event_handler) {
+ evt->event_handler(evt);
+ }
+ else
+ printk("WARN:ipi_timer: event_handler missing\n");
+ }
+ else
+ printk("WARN:ipi_timer: evt not set\n");
irq_exit();
}
Beyond this any additional issues, I have to check yet. Also the reason for this race, I haven't debugged for now.
UPDATE1 (Step3)
----------------------
I have further cross checked that CONFIG_OMAP_RESET_CLOCKS causes some problem in linboothkvc Nirvana environment for few specific clocks, either way for now Disabling this config in BN NookTab kernel before compilation will allow the resultant kernel to run SUCCESSFULLY on NOOKTAB.
NOTE: As of now, even thou SMP is enabled, one of the Processors doesn't come up live. That has to be debugged later. But otherwise the Linux is FULLY running in NookTab from with in the LinBoothKVC Nirvana Environment and in turn the Linux User space is also running fine.
That sounds like a big step. Awesome work!

- You can use nearly any Linux distro. I suggest either Debian or Ubuntu, as both of them have excellent support and are very easy to install and use, compared to some other ones. However if you feel fine in Linux environment, you can install nearly any distro you like.

ArchiKitchen Questions & Answers
Q: What is this "ArchiKitchen"?
A: A Linux-based kitchen, with a main objective of converting stock ROM drops in .img, .tar.md5 or similar formats to CWM-flashable .zip.
Q: So I can create my own custom ROM based on stock ROM with it?
A: Exactly.
Q: Is it for Linux only? Why windows is not supported?
A: Let's face it, Android is based on Linux kernel and we could call it a mobile UNIX fork. It's hard to work with Linux-based things on Windows, in fact, Windows doesn't even offer Bash (Bourne-again shell), which is absolutely core for ArchiKitchen. Working with windows is painful, for example - .img mounting. I can very easily mount any filesystem image on Linux with just one command, while doing so on Windows usually requires a massive convertion of whole image to .zip file, then extracting a single files. Also, Windows doesn't support symbolic links, and this makes it impossible to create 1:1 copy of the image "translated" to zip file. Therefore, making a Windows port would require lots of more work and solving issues, and even with that it would still cause some core features to be unavailable. However, launching Linux on Windows is very easy thanks to VirtualBox and other virtualization software, so you don't need to reformat your PC or stick purely with Linux. In fact, this is the proposed way of using ArchiKitchen - Installing a native Linux distro (suggested: Debian or Ubuntu) and then installing ArchiKitchen on it. Take a look at tutorial to see how easily you can install and run ArchiKitchen in Linux VBox.
Q: Is Cygwin supported?
A: No. Cygwin IS NOT supported and it's not planned to add such support. Reason is nearly the same as above one. However, ArchiKitchen is open-source project and I'm open for all pull requests, so perhaps somebody will add support for Cygwin in the future. Until then, ArchiKitchen is compatible ONLY with Linux, and if you use it on Cygwin you're on your own with the issues that may happen.
Q: Which phones are supported?
A: ArchiKitchen contains a local "database" of devices, which includes a kernel/modem blocks to be used. However, as long as you know the partition layour of your device (kernel block), ArchiKitchen works with every phone and every Android variant. I'm trying to make it as universal as possible, so even if your device does not exist in our local database, it should work.
Q: How can I add my own phone to the local database?
A: If it doesn't exist yet, take a look at "product" folder. Inside you can notice various devices with name based on their models. ArchiKitchen will detect your ROM's model and check inside if it exists, if it does, then some properties for this model will be loaded, if it doesn't exist, then ArchiKitchen will ask user for them. Probably the best idea is to copy one of the already available models (for example "m0" - Samsung Galaxy S3), then rename new copied folder to your model name and finally edit files inside.
Q: What is "NULL" text found for example in some MODEM files in the database?
A: Some phones have a possibility to flash modem directly from CWM, others don't. "NULL" text indicates that this model does not support flashing modem.bin, so even if ArchiKitchen finds and recognizes it, it will pop up an error telling you that it unfortunately can't be used.
Q: Where is SYSTEM block?
A: System block is not being used at all, as it's a valid partition and should be located in "fstab" file in recovery already. ArchiKitchen mounts system automatically through "mount" binary, with automatic filesystem and /system path. I consider providing a system block as something obsolete, because it's only required when you're formatting a partition, and even during flashing, a wipe - delete_recursive() function is enough. Therefore, ArchiKitchen does NOT require providing a /system block.
ArchiKitchen Troubleshooting
Q: It looks like something is wrong with zipalign command. I can notice errors like "./zipalign: No such file or directory"
A: This is because zipalign is x86 binary (32-bit), while you have amd64 (64-bit) Linux. Therefore, we must install some missing core packages to properly support x86 binaries. This will do the trick:
Code:
apt-get install lib32stdc++6 lib32z1
[SIZE="+1"]ArchiDroid Init.d[/SIZE]
ArchiDroid Init.d is an innovative method for including init.d support in the ROM itself, and not in the kernel. ArchiKitchen supports adding ArchiDroid Init.d to any Android ROM.
ArchiDroid Init.d is based on two files. A core - debuggerd hook, and a check part - simple init.d script.
Init.d script is named 00ARCHIDROID_INITD, and it only creates a special file to notify the core that init.d has been already executed, therefore it can't conflict with anything and it's completely safe.
The core is a hook for special /system/bin/debuggerd binary, which is normally called once during initial boot. Therefore, when it's called, ArchiDroid Init.d firstly waits a specified amount of time (default: 5 seconds), in case if user has already a kernel with init.d support. This is required because otherwise all init.d scripts would be executed twice - by kernel and our init.d. After specified time, if init.d is still not executed, our hook executes all scripts in alfabetical order. Lastly, when we're done, hook is executing original debuggerd binary (default: debuggerd.real) and shares the environment, arguments and everything. This is a perfect method for implementing init.d in the ROM itself, because we don't need to trust the kernel that it supports and executes init.d properly. We give it a 5 seconds to execute it, and eventually we do the job if kernel is not interested in that. This way we can support both custom kernels with native init.d support (we wait initial delay, if kernel executes init.d, all is fine and we don't have to do so), and also pure stock kernels without init.d support (we wait initial delay, kernel doesn't care about init.d, so we're executing it).
I think that such hook works far better than relying on the kernel and modyfing stock ramdisks. Also we're sure that even if user changes kernel to any custom one, we still have reliable init.d support, regardless if custom kernel supports init.d or not.

Looking forward.
i really appreciate your work, like every time
In general whole kitchen needs a magic touch more or less but firstly I'll want to make it fully usable (and modern!) then eventually rework it.
As for now it's more or less up-to-date. Also added Note3 variant.
Thanks for your work and projekt!
I will download and test it with the new Galaxy Note 10.1 2014 :good: (Android 4.3)
Feel free to test it, but keep in mind that it's still work in progress .
Today I've added new experimental method for *better* handling setting up rom directory. As for now it supports only system.img in sgs format, however it automatically extracts it (if needed) from any tar/zip package, also with properly detecting cache.img. This is the main feature I was missing in original kitchen.
https://github.com/JustArchi/Android-Kitchen/commit/cf025ebf6573d23e5d2b7cfde258d9b7c36abd29
Just please don't track "wip" branch, as it's rebased often and merged into master when ready .
This is great, as I love the kitchen it is awesome that you've updated it. I'll be trying it out tonight. Thanks for your work.

Actually kitchen can work only with update-script, although it converts it to updater-script when building rom.
This is on my todo but it's a bit complicated (many dependencies), so it needs major rework.
As for now I suggest avoiding conversion before final build.

Thanks.
Also
1. with koush rooting theres no deamonsu in xbin, is this right?
2. when rooting the kernel is still ro.adb.secure=1 should be 0 or?
3. would be great if the kitchen adds a modded adbd in ramdisk/sbin (to get root directly in adb)
Again thanks

1. That's right, koush doesn't have direct support for su daemon.
2. User should be able to modify this, on todo with many other things...
3. I think we can do it, soon .

i worked with planty firmwareswith the latest kitchen for my devices but anytime the SuperSu after installation was saying something like "there is a SuperSu, but not Supersu binary installed". that thing was gone after i flash the SuperSu update binary. Does your kitchen gonna give me SuperSu from the start (instalation)?

Release notes
This build includes a totally new kernel and Amlogic code based on their latest SDK, and I took the chance to get rid of Amlogic DVB drivers and use those from WeTek Play's OpenELEC build; by doing this I am able to run DVBAPI apps like Tvheadend.
Kodi Live TV support under Android was one of the most requested features, this experimental build allows you to run Kitkat (CyanogenMOD 11) or Lollipop (CyanogenMOD 12 or Android TV) and Kodi Live TV (WeTek Theater is no longer supported with the provided drivers).
The new 3.10 kernel brings OMX support as well (Android libstagefright media decoding), while Amlogic's prebuilt libraries work very good on KitKat they don't work at all with Lollipop.
Just to be sure to have a good media experience use Kodi, at the end of the post you will find latest stable official Kodi packed in a flashable zip and in the second post you will find a link to a modified version that should give a better experience on the WeTek device.
Now I will give you some details on how to configure Tvheadend, if you already know what to do you can skip this section.
Tvheadend will run automatically at boot and you can access to it from a web browser (even from a different device, you are not forced to do it from the box) at http://wetek_ip_address:9981
From this WebUI click "Configuration" -> "DVB Inputs" -> "Networks" and add a new Network according to the type of tuner you have (for example I created a DVB-S network called "Hotbird" and assigned the E13.0 pre-defined muxes, just pay attention that they are not bleeding edge updated so if you don't find a channel you might have to insert manually the transponder by looking at frequencies on sites like kingofsat or lyngsat).
After that go to "TV Adapters", click the link with a folder icon showing your adapter's name (if you're running the dual DVB-S2 tuner you will see two of them, #1 is the input closer to the edge of the box, while #0 the one closer to the rear usb ports), and click "Enabled", configure the eventual parameters (DiseqC, Unicable, etc.) and save the settings.
Go to the option right under the adapter name, assign it to the network that you have created and configure the eventual parameters.
Now go back to "Networks", after a couple of minutes you should see the "Scan Q length" lowering its value, when in reaches 0 everything has been scanned and you can proceed mapping the channels from "Services" section.
For further instructions, here you can find a tutorial to show you how to configure the DVB-T/C tuner, and here one for the DVB-S tuner.
Before leaving the configuration go to "Recordings" and set a "Recording System Path" pointing it to your external storage (on my roms it will be "/storage/sdcard1" for the MicroSD, "/storage/usbdisk0" for the lower rear usb port, "/storage/usbdisk1" for the upper rear usb port and "/storage/usbdisk2" for the side usb port).
Not doing that will drive Kodi's Tvheadend client plugin crazy trying to determine the available space for recordings.
Now you can launch Kodi, go to its settings, enable Live TV and select the "Tvheadend backend".
Remember that this is still something EXPERIMENTAL
Like the other Lollipop buils, remember, this is not a bug, but a consequence of the switch to art from dalvik: first boot, updates and apps installation will take longer; this happens because art compiles the apk and does not work like dalvik that was using a just-in-time approach (so expect almost 10 minutes for the first boot and future upgrades)
First install instructions
* As really first thing get this CWM recovery, unrar it and copy "recovery.img" to a MicroSD.
* Power off your device and unplug the AC power cord.
* Get the latest available ROM and GAPPS version from the links below and copy them to a MicroSD card.
* Now insert the MicroSD card in your STB.
* Plug the AC power cord while you keep pressed the little reset pinhole (located on the bottom of the device) for 10 seconds (just count slowly to ten and it will be good).
* Once the device has booted to recovery perform a factory reset and flash the ROM's zip for first followed by the GAPPS zip.
* Reboot and enjoy CyanogenMOD.
Update instructions
* If you're coming from the "regular", not "experimental" builds, please follow the "First install instructions"
* Get the latest available ROM and GAPPS version from the links below and copy them to a MicroSD card.
* Now insert the MicroSD card in your STB.
* Enable "Developer options" following this tutorial and from it enable the "Reboot to recovery" option.
* Bring up power menu by keeping pressed the power button on the STB for a couple of seconds (or pushing F4 if you have a keyboard plugged in) and select "Reboot -> recovery".
* Once the device has booted to recovery flash the ROM's zip for first followed by the GAPPS zip.
* Reboot and enjoy your updated CyanogenMOD.

Misc tips
* If you wanna start Kodi at boot go to "Developer options" and enable the last entry called "Start Kodi at boot"
* There are some keyboard shortcuts: F1 (Home), F2 (Menu), F3 (App switch) and F4 (Power menu) and some CEC remote shortcuts: Red (Power off the device), Green (Home), Yellow (Menu) and Blue (Search).
* By enabling "Google remote support" in "Other" section of "Network" configuration you will be able to control your device from your Android smartphone / tablet by using this app on it.
* When an app forces the portrait orientation, the default behavior is to simulate a portrait / phone-like UI adding black bars to the sides (an example is Antutu when it runs the benchmark, or Box.com). If you prefer to have a landscape stretched UI flash this zip. To revert to the default behavior flash this one instead.
Note that the setting will persist even if you upgrade the ROM so you have to flash that zip only once.
* Once you have configured your OSCam reader, set-up Tvheadend this way.
Real 1080p output (optional zip for CM11)
On Android Amlogic MX SOC uses a 1280x720 framebuffer coupled with a scaler to do the up/down scaling.
They did it for a good reason, 720p resolution has half the pixels of the 1080p one so the UI will be snappier and 3D performance will be better but if you don't care about that and you just wanna the best image quality (I noticed the scaler gives me a weird motion when watching sports) you can flash that optional zip.
Once flashed if you wanna change resolution go to Android Display settings, set your resolution and reboot the device (this step is required because some stuff has to be set at boot because Android is not meant to change resolution while it's running).
I didn't do it for Lollipop builds because it runs already slower than Kitkat, adding this mod might be too much
Since you have this option (WeTek Play is the only MX device that allows you to do that) I would give it a try, if you have a good TV set you will clearly see the difference.
Kodi 14.2 WeTek_mod_v1
This is a Kodi build that includes some patches not included upstream that will improve (hopefully) your overall experience.
Since it's been signed with different keys respect those from Kodi build server you won't be able to install it over the older Kodi but you'll have to uninstall it.
Take a backup of /sdcard/Android/data/org.xbmc.kodi folder before uninstalling or Android will delete it and you'll lose your configuration; restore it after installing the new APK.
Download
You can use OE's /sdcard/Android/data/org.xbmc.kodi/files/.kodi/userdata/advancedsettings.xml file

External disk spindown for WeTek Play
Flash this zip from recovery, once booted to android use a root capable file explorer (like Solid Explorer for example) and edit "/system/etc/spindown.conf" to fit your needs.
The default configuration is set-up to spin down "sda" disk after 3600 seconds (60 minutes) using sg3-tools.
You don't need to flash the zip again if you do a rom update because I've added the addon.d backup script.
Note: your drive have to ne able to be set to sleep using "sg_start --stop /dev/block/$disk", I've tried it with 3 drives, 2 WDs and 1 Seagate and it worked.
Debian chroot
As very first thing you have to set-up a MicroSD card with two primary partitions, the first one must be formatted in FAT32, the second one can be left unformatted because the "sdcardfiles" zip will format it (I suggest you to give at least 1GB of space to the secondary partition).
After that grab the two zips: wetek-debian-chroot-sdcardfiles.zip and wetek-debian-chroot-systemfiles-rc1.zip and copy them (together with CWM's recovery.img) to the FAT32 partition of the MicroSD (the primary one).
Boot to recovery and flash the two zips (the order doesn't matter).
How to actually use it:
The "systemfiles" zip will add an helper file that I called "debian-chroot", together with the init.d script it will set up the chroot at boot and run the configured services (as a template the /system/xbin/debian-chroot file includes the execution of dropbear daemon, so you can use it as starting point for your own stuff).
To access Debian you can just type as root from terminal emulator / serial console / adb over network "debian-chroot chroot", othwerise you can access using an SSH client to the configured Dropbear SSH server that is listening on port 2222.
There are two default users: 'root' (pwd: wetek) and a regular user 'wetek' (pwd: wetek), both can be used to access to the ssh server.

In the "regular" CM12 build added some things I had forgotten when upgrading the device tree from the old to the new kernel (the most important, I had forgotten to mkdir the paths for the hard drives mounting).
Included the new tvheadend posted in OpenELEC section (the one with the different decsa algorithm)
Added Android TV build and just a tip for the first boot of it...
Don't change the language, use the default english already selected (don't know why but changing language is VERY sluggish/laggy), when you're doing configuring it you can change it to your preferred one in Android's settings.
Another thing, if the screen stays black after allowing or denying the "Network location" option (the last step of the wizard) for more than 10 seconds just bring up power menu and perform a reboot, the Wizard will kick in again, you'll have to just click continue because everything is configured and it will work. I don't know why it acts like this sometimes!
Guys if you experience some freezes of the box after running for certain time an encrypted channel (I noticed that it happens to me between 45/60 minutes after tuning to such channels) it might be caused by the new decsa library, it looks like it has a memory leak.
I will revert to the older binary, in the meantime you can flash this zip to go back to the one from the older build.
After reverting I'm tuned on an encrypted channel since an hour and I don't see any weird memory issue
Oh, guys, I forgot to mention that in this build I've enabled Amlogic's "anymote" support (the backend to be remotely controlled use Google TV remote app).
To use it go to "Network -> Other" options in Android's settings and enable "Google TV Remote support", after that install this app on your Android phone/tablet and you'll be able to use it as a remote.
PS: I didn't have much luck running the "Google TV Remote" app from the Play Store, it wouldn't find the device at all, maybe they are enforcing a private key handshake like in newer Google Cast Receiver to be able to run it only on official Google TV devices.
PPS: remote audio input doesn't work, the Amlogic's anymote throws an exception regarding a class not found. Can't do much about that since it comes as a precompiled APK (and I already had to do some smali hack to be able to run it on Lollipop)

Lollipop ROMs:
* Reverted tvheadend to the older version that doesn't suffer of memory leak
* Introduced a workaround to prevent Netflix from using OMX
* Updated upstream sources
Kitkat ROM:
Added CM11 based on the new kernel. It's generally faster than Lollipop, as I have said ART probably is too much for the MX
I haven't added the extra stuff to Android settings so I'm including the ugly MboxSettings app, I have given more love to Lollipop, I have to admit it, in case if you people prefer this rom I can start customizing it more.
I suggest you to install SuperSU from Play Store, let it update the "su" binary choosing the normal way and converting it into a system app + installing the backup script to let it survive rom updates. This because CM11's SuperUser doesn't work nicely with the way Kodi request root rights.
Beside the same F1/F4 shortcuts as the Lollipop roms above, there's a further shortcut with F8 to toggle expanded desktop mode.
* ROM (CM11) 2015-02-01
* Added the most important things of MboxSettings to Android settings (display resolution, overscan, cec, digital audio and google tv remote).
* Added an entry, accessible through developer settings (at the very end of the list), to enable the autostart of Kodi at boot
* ROM (CM11) 2015-02-02
* added the new suspension method (I will quote my previous post to describe it)
ChristianTroy said:
Guys I've been trying a new suspension method, it's a better solution IMHO.
I'm going to use Android's capabilities to prevent the device from entering suspension (with wakelocks) to only let the kernel turn off everything but without really entering suspension, something like flashing the "wetek-disable-shutdown.zip" that you find in the second post of all my other rom's threads.
But I did a modification in the kernel: it will turn the power led blue/red if the display is on/off so you'll know if you actually turned it off. I decided to mantain on the eventually enabled wifi or eth led so you'll see if you have connection or not.
This thing is very useful if you're going to program a recording in tvheadend, otherwise the device won't wake from sleep (at least not with easy work without using Android's AlarmManager to create a new wake up task) and in this way the device won't have to perform boot from scratch once you put it to sleep, but it will be instantly on again.
It will consume a little bit more of power though (haven't run much tests but since this device when it's on runs at 7w, I guess it will be <5w) but I think that many of you keep it running all the time, in this way it's like if it was running but just with the output turned off

* corrected an unwanted (by me) behavior of Amlogic's android ethernet service that was putting off the interface when the display was being turned off. If you were connected using eth you would find yourself without network with the new suspension method... if for some reason you want your eth to be turned off when the display is off add "ro.screen_off.disable_ethernet=true" to /system/build.prop
* disabled google setup wizard that was causing a black screen on first boot because it was invoking the AOSP version of setWifiEnabled instead of CM's one with AppOps support
* enabled the execution of a boot service to set up the remote (you couldn't power off the device using the remote before this build) that I had forgotten to set up after moving to the new kernel branch
ps: let me know what you think about this new suspension method, personally I do really love it and was thinking about that since quite some time

Boot to recovery and flash the two zips (the order doesn't matter), after each ROM upgrade you'll have to flash only "wetek-debian-chroot-systemfiles.zip" (the other one is just to set up Debian, flash it in case you mess up the system and wanna start from scratch).
How to actually use it:
The "systemfiles" zip will add an helper file that I called "debian-chroot", together with the init.d script it will set up the chroot at boot and run the configured services (as a template the /system/xbin/debian-chroot file includes the execution of dropbear daemon, so you can use it as starting point for your own stuff).
To access Debian you can just type as root from terminal emulator / serial console / adb over network "debian-chroot chroot", othwerise you can access using an SSH client to the configured Dropbear SSH server that is listening on port 2222.
There are two default users: 'root' (pwd: wetek) and a regular user 'wetek' (pwd: wetek), both can be used to access to the ssh server.
Regarding the random black screen on channel change can anyone try this advancedsettings.xml (location on Android is "/sdcard/Android/data/org.xbmc.kodi/files/.kodi/userdata/") and tell me if it acts better? I didn't have any black channel since using it (3 days) but I don't wanna that it's just a lucky coincidence
Code:
<advancedsettings>
<network>
<buffermode>1</buffermode>
<cachemembuffersize>52428800</cachemembuffersize>
<readbufferfactor>10</readbufferfactor>
</network>

<minvideocachelevel>10</minvideocachelevel>
<minaudiocachelevel>15</minaudiocachelevel>

Regarding the XMLTV EPG I set up xmltv to use tv_grab_it for some channels (47 to be precise, and it takes ~1 hour per fetched day with the --slow parameter that includes descriptions) and fix it using tv_sort on the generated output because some channels don't have a stop time and this won't let tvheadend add them to its database.
I used a Debian chroot in my Synology NAS and set up a crontab job in Synology's crond to execute a script, located at '/root/xmltv.cron' with this content:
Code:
#!/bin/sh
# Package
PACKAGE="debian-chroot"
DNAME="Debian Chroot"
# Others
INSTALL_DIR="/usr/local/${PACKAGE}"
PATH="${INSTALL_DIR}/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/syno/sbin:/usr/syno/bin"
CHROOTTARGET=`realpath ${INSTALL_DIR}/var/chroottarget`
chroot ${CHROOTTARGET}/ su -c 'tv_grab_it --output /volume1/homes/alan/www/tvguide_wip.xml --days 3 --quiet --slow --cache-slow && tv_sort --output /volume1/homes/alan/www/tvguide.xml /volume1/homes/alan/www/tvguide_wip.xml' alan
After that I enabled "Web Station" for the users and I can access my EPG from "http://NAS_IP/~alan/tvguide.xml" and use this URL as w*g*e*t parameter for tv_grab_file
This is the result:
If you install on your Play the Debian chroot that I posted yesterday you can practically do the same, just install xmltv on it running
Code:
sudo aptitude install xmltv
(or, if you know what you're doing, compile it from sources installing the required dependencies, some perl modules)
Install a cron daemon like "vixie-cron" and add it to "/system/xbin/debian-chroot" in the "start_services" function (like the template that runs the SSH server).
Set it up, save the XML output somewhere like "/home/wetek/tvguide.xml" and replace the "w*g*e*t" line in tv_grab_file with "cat /storage/debian/debian-chroot/home/wetek/tvguide.xml"
* ROM (CM12) 2015-02-07
* ROM (Android TV) 2015-02-07
Both Lollipop roms have been updated to match features/fixes of latest CM11 builds, plus upstream sources have been updated
New builds:
* ROM (CM12) 2015-02-14
* ROM (Android TV) 2015-02-14
* ROM (CM11) 2015-02-14
* OSCam (r10566)
Oscam zip for these builds, just flash it from recovery, when booted into Android access to http://wetek_ip:8888 and add your server (remember to add it to group 1, that is the group assigned to the dvbapi user).
Open TVH configuration page and in "CAs" section add a new "CAPMT (Linux DVBApi)" with these content:
ps: this oscam has Smargo (libusb) and PCSC support
tvh-3.9.2509_oscam-r10566_android-wetekplay.zip
New Tvheadend built from sources (updated this morning), no more using OE's libraries but with another approach instead. I've built it with some enhancements in CFLAGS for the cortex-a9 cpu.
OSCam included, if you set it up the way I explained yesterday you're good to go, otherwise just configure it that way
ps: it looks like this version recognizes the hybrid c/t tuner as c only so if you need dvb-t keep using the one you're already using
* ROM (CM12) 2015-02-22

* ROM (CM11) 2015-02-22
tvh-3.9.2515_oscam-r10607_android-wetekplay.zip
Test zip that will change the following things:
- update tvh to latest sources (synced this morning)
- update oscam to r10607
- update wetekdvb.ko with the one from OE 5.0.4
PS: now the hybrid tuner is recognized, I had to change a couple of things
* ROM (CM12) 2015-03-05
* ROM (Android TV) 2015-03-05
* ROM (CM11) 2015-03-05
If you're upgrading from a build where you were running oscam, go to "mounts and storage -> format /system" before flashing the new stuff (or manually delete "/system/addon.d/80-oscam.sh" if you know what you're doing).
Changes:
* updated upstream code
* updated WeTek DVB kernel driver
* updated Tvheadend
* added OSCam (no support for it, it's a "grey area" thing)
* fixed a bug where the resolution was resetted to 720p @ 60hz under certain conditions (like when swapping HDMI input in some TVs), and use 1080p @ 50hz as fallback resolution
In case you wanna try a test zip with brand new OSCam and Tvheadend built with Android toolchain (NDK) flash THIS zip on top of today's build. I'd really like some reports about any crash using the native binaries.
Kodi 14.2 BETA 1 apk
This is a Kodi 14.2 BETA 1 based build with two patches added that add support for automatic frame rate switch (you have to enable it in settings) and that should behave better with the black screen bug.
Since it's been signed with different keys respect those from Kodi build server you won't be able to install it over the older Kodi but you'll have to uninstall it.
Take a backup of /sdcard/Android/data/org.xbmc.kodi folder before uninstalling or Android will delete it and you'll lose your configuration; restore it after installing the new APK.
Download
I'm using this /sdcard/Android/data/org.xbmc.kodi/files/.kodi/userdata/advancedsettings.xml file

* ROM (CM11) 2015-03-10
- CEC improvements (codesnake's OE fix)
- Mapped CEC red/green/yellow/blue buttons to power/home/menu/search
- upgrade tvheadend and oscam with the native (android ndk) ones
- updated dvb code (same code as latest OE)
- few other minor things at kernel level
- updated upstream sources
Notes: run it with Kodi that I posted yesterday (and that you can find in the second post) with Aeon Nox skin + Live TV mod and you will get a very good experience, specially if using CM11 or, if you don't mind it being a bit more laggy, ATV
* ROM (CM12) 2015-03-11
* ROM (Android TV) 2015-03-11
* ROM (CM11) 2015-03-11
Fixed a problem with the dual tuner and the new bootloader (the one flashed by NAND version of OE and latest WeTek OS)
