[Q] Backup of disk encryption master key - Android Q&A, Help & Troubleshooting

I've been extensively searching on this, but I just can't find any answer, although I really can't image I'm the first one to come up with this.
I have a Google Nexus 4 (rooted, of course) and I'm using the native phone encryption.
There is some information that can be found, revealing that google uses the native linux dmsetup tool for this.
Now, just in case anything goes wrong, I'd like to have a backup of the encryption master-key,
that I could use to restore the dm-crypt header.
On a normal linux system, this would be easy, only one call to dmsetup and I'm done.
However, I just can't find any info to do this on android.
The UI doesn't offer this option (as is to be expected) and I just don't know how to do it by using adb.
I've opened a root shell session and tried some commands (dmsetup, cryptsetup, some calls to "vdc cryptfs", etc...), but I just don't find a way to do it.
Has someone already found a way and can share how it's done, any ideas?
Thanks in advance

Does no one encrypt their android phones or is concerned about integrity of their data?

I think you overestimate Android: In most cases /data partition is not larger then a few GB's on smartphone devices.
Just insert Storage card with enough free space, and do a decrypted backup (for example from CWM recovery being root):
1) Make sure /system, /sdcard, and /data are all mounted inside recovery environment
2) /system/xbin/tar -C / -cf /sdcard/data.tar data
When integrity of your data is no longer given, you can factory reset the device, start again the encryption process (which will use a new key for encryption), and then restore your userdata back:
1) Make sure /system, /sdcard, and /data are all mounted inside recovery environment
2) /system/xbin/tar -C / -xf /sdcard/data.tar
No need to play around with keys and cryptsetups or being afraid you loose data because you have encryption enabled
---------- Post added at 04:12 PM ---------- Previous post was at 03:14 PM ----------
To answer your initial question:
Have a small lecture on h*t*t*p://source.android.com/tech/encryption/android_crypto_implementation.html
It is said, that the "The crypto footer contains details on the type of encryption, and an encrypted copy of the master key to decrypt the filesystem".
And that "[..]the filesystem doesn't extend into the last 16 Kbytes of the partition where the crypto footer is kept".
So basically by doing a backup of the last 16KB of the partition initially was mounted as /data before encryption you are THEORETICALLY save.
I am sorry not being able to give you exact commands, but i am sure someone can post you the right partition name (e.g. for HTC vision devices it would be /dev/block/mmcblk0p26), you can do backup/restore on blocklevel using dd, which is on my current ROM located at /system/bin/dd
You then need to find out the size of this partition, which in my case with /dev/block/mmcblk0p26 would be:
cat /sys/class/block/mmcblk0p26/size gives yout size of partition in blocks (in my case 2234367)
Now you have to reduce this by 16KB, whish i think should be (2234367*4096-16*1024)/4096=2234363, because i think on all Android devices Blocksize is 4096 (you can check the column Blksize on output of shell command "df" on Nexus).
Commands would be then something like this:
Backup: /system/bin/dd if=/dev/block/mmcblk0p26 count=4 bs=4096 skip=2234363 of=/sdcard/masterkey.dd
Restore: /system/bin/dd of=/dev/block/mmcblk0p26 count=4 bs=4096 skip=2234363 if=/sdcard/masterkey.dd
Because 16KB are 4x4096 Byte
With THEORETICALLY i meant that these are my thoughts based on the implementation description, which might be accurate enough about the master key, or not (often the master key is stored on a special sector, and they only mentioned a "region" for the crypto footer), and i never tested above Backup/Restore commands, yet.
Perhaps someone better knowledged can confirm my calculations, or someone who digged in the right passages of the Android source can tell us where exactly the master key is getting stored!

Thanks for the answer.
I'll give it a try and store a backup of that last few kb of the disk.
However, since I can't really test if a restore works,
I wouldn't put too much trust into that backup.
Thanks anyway

Has anyone been able to backup their key? Anyone confirmed the commands that rondald put?
This is ridiculous that the SD card is locked to the device. I need to transfer my SD Card to a new device and should not have to reformat my SD Card.
Encryption without key management = FAIL

[NEW] New patches on kernel from December update from Archos git
[NEW] Full iptables support (with NAT, conntrack etc) - so everything is now possible (redirect, proxies etc)
[NEW] Full kernel timing for power consumption monitoring
[NEW] Recompiled WiFi? and HDMI drivers
[NEW] Added python 2.7, iotop (for watching i/o operations), PowerTOP (for power consumption monitoring - but it's not as useful as on x86)
[NEW] Added ntfs-3g support - full read/write support for NTFS file systems (need to be used manually, vold does not use it)
[CHANGE] Added UrukDroid? Rescue Menu - Repair submenu with disabling overclocking (for those who made their device unbootable with overclocking) and Dalvik cache cleaner
[NEW] New feature in cpugovernor script (genconf, current)
[CHANGE] New features in update subsystem
scripts now tries to keep /data/.tmp directory cleaner,
for those with disk shortage /data/.tmp can be now symlink to directory on sdcard
updater now checks if you have enough free space in /data/.tmp before it begin installation
update process now can be during bootup (better one) if you have enough free space on rootfs, or on running system (not so nice - this is default behavior until UD 1.6 release)
[CHANGE] restoring backup in Rescue Menu now erases partition before restore (until now it was just overwriting)

[CHANGE] Since UrukDroid? 1.1 (both beta1/2/3 and release candidate 1/2/3) had stability and compatibility issues - that I was unable to trace down (too many changes on changes etc.) - I've decided to implement all stuff from beginning on fresh OS. Since all "reverse engineering" stuff was already made and I already have required knowledge - It should be the fastest method. So entire system is cleaned up, updated to latest binaries - and so far looks good . That's why I've bumped version to 1.5 - just to make it a bit more visible it's not a straight continuation of 1.0/1.1.
[FIX] No more "soft reboots" (system reloaded it's graphics UI part)

FAQ or Tips & Tricks
More information you can find in seperate thread on this forum - FAQ + Question/Awnsers
How to upgrade from previous releases
To upgrade from 0.5 you should download special upgrade file (UrukDroid-0.6-upgrade.tbz2) from first post. You need to place this file in directory "/data/UrukUpdate".
First method:
Put it on your internal storage by any means - this is /mnt/storage (also visible as /sdcard/). Then use file manager (like Astro or RooteExplorer - not build in one) or do as follow in terminal (or over ssh)
Code:
su
cd /sdcard/
mv UrukDroid-0.6-upgrade.tbz2 /data/UrukUpdate/
Second method:
Use UrukConfig to enable SSHD (if you don't have it started already), and use any SCP/SSH client (like WinSCP, or plain scp on Linux) to copy file (default username is "root", password is "UrukDroid") to "/data/UrukUpdate".
In both cases upgrade will start automatically; alter kernel, initramfs and when finished, device will reboot itself.
How to enable/disable and configure UrukDroid services?
UrukDroid services are configured by text files, that can be found in /etc/uruk.conf/ directory. You can use file manager like RootExplorer or Terminal to edit them, but most convinient way is to use SSHD service and some ssh client (for example putty).
You can also use UrukConfig application - build in since 0.5 release. After you do some changes, restart service (/etc/uruk.d/service_name stop/start) or simply reboot Archos. Since 0.5, by default only CompCache and CPUGovernor are enabled.
Currently available services
samba - it's SMBD server allowing mounting your Archos storage directory on your PC. Default user is "storage" and password "UrukDroid"
sshd - SSH server allows you to connect to your Archos with any ssh client, work on terminal. It also allows to copy files with scp/sft. Default user is "root", password "UrukDroid"
swap - this service enable swap memory. It can make Archos a bit less responsive but memory manager won't kill application so quickly (co you can use WWW browser, email an communicator simultaneously - for example of course)
iptables - this pseudo service will load necessary modules to use iptables (firewall) features
ntfs - if you plan to connect NTFS formatted devices to your Archos - enable this service
dvb - this service load necessary modules to watch TV on your Archos. This service requires configuration from your side - it won't work "as is". Please read and edit config file (/etc/uruk.conf/dvb)
compcache - Start/stop CompCache swap memory service. Compcache is a compressed part of memory, where less used object reside. Usual compression ratio is 70%
cpugovernor - Changes default CPU governor and it's parameters. Governor decides how to scale CPU frequency. Since 0.5 there is new "interactive" governor.
openvpn - It's an implementation of popular free VPN service for Uruk. It will act like the one used in Archos stock config with difference it will work all the time - whenever you go, and you have full flexibility of configuration. Config file resides in /etc/openvpn/archos.conf.
VPNC - It's open implementation of Cisco VPN service. You should edit /etc/vpnc/archos.conf file.
NFS4 - NFS v4 client service allows you to mount remote file storage with use of NFS (much faster then SMB for example). You can also enable use of cachefilesd sub-service - that will cache locally, files transferred with NFS (for smooth playback of movies for example)
How to remove some default apps?
App started at the boot time are stored in /system/app, I've already removed some of them by moving it to /system/app.old/ - but you can do it by your own - but remember - some of them are actually required to run system
Some filesystems benchmarks (that's the reason why I wanted ext4 so badly)
Write tests (I've testes different filesystem and partition sizes)...
Tests on Archos:
internal 8GB
0,71Mb/s ext3,ordered,noatime
5,45Mb/s fat32
Lexar 16GB
2,63MB/s ext3,ordered
6,25MB/s ext4,ordered
Test on computer (the same lexar card)
2.93Mb/s 1GB,ext3,noatime
2.78Mb/s 1GB,ext3
3.04Mb/s 1GB,ext2
8.62Mb/s 1GB,vfat
7.61Mb/s 1GB,btrfs
7.87Mb/s 1GB,ext4
7.87Mb/s 16GB,ext4
Card is 16GB SDHC Lexar class 6 only - so this toshiba nand inside is not state of the art either :/
How to roughly check your filesystem write speed
Go to directory where you can write and were is more then 100MiB of free space and do the line. It will sync devices (flush all write caches), write 100MiB file filled with zeros, and fush caches once again to measure real write speed without buffers. Then easy math... and my laptop disk has write speed 16,66MiB/s
Code:
[email protected]:/tmp$ sync; date; dd if=/dev/zero of=test.file bs=1M count=100 2>/dev/null; sync; date
Wed Jan 5 19:02:28 CET 2011

UrukDroid configuration system
I've created (or recreated, since Google threw away existing Sytem V and other solutions) something that works like rc/init.d system. It's old fashion, but for only few services will do it's job.
There are few location to remember:
/system/etc/uruk.d/ - directory with services
/system/etc/uruk.conf/ - directory with configuration files
/system/etc/init.d/ - symlinks Sxxserice/Kxxservice (like S01swap) to be run during startup process
Proper path is /system/etc/ but it's symlinked on every Archos to /etc - so you can also work on /etc/uruk.d, /etc/uruk.conf etc.
To enable iptables support (load proper module) it's enought to edit /system/etc/uruk.conf/iptables
To change swap memory settings edit /system/etc/uruk.conf/swap
How to mount ext4 under Windows?
There is project called "ext2read" that claims to work with ext4 also (I've only tested it with ext2 long time ago - it worked) http://sourceforge.net/projects/ext2read/ - please write some commends if you use it.
What is current directory/disk layout?
/ -> SDCard first partition (512M) - for root filesystem
/data -> SDCard second partition (1GB) - for installed apps
/mnt/storage -> internal 6GB partition - for data used by installed apps
/mnt/storage/sdcard -> SDCard third partition - anything you want, nothing by default
/mnt/sdcard2 - proposed mount point for other volumes, not used by default
And there is something called symbolic links (symlinks) - witch is kind of Win shortcut used on UN*X extensively.
/sdcard -> /mnt/storage
/storage -> /mnt/storage
/mnt/sdcard -> /mnt/storage
So you can enter /sdcard - and you are be using files from /mnt/storage. You can also create symblinks by yourself
Code:
ln -s /source destinations
How to gather data report from UrukDroid
Best way is to use SSH. For this, please start "sshd" service on UrukDroid by using UrukConfig application or by editing /etc/uruk.conf/sshd file.
First start will take one minute or so - since sshd has to generate unique encryption keys.
If you use Windows download putty.exe (ssh client) and run it. Write your Archos IP (it has to be visible in network) and connect.
Use
Login: root
Password: UrukDroid
Click to expand...
Click to collapse
Now you can write Linux commands and cut/paste results for help/debug purpose.
Thanks!
I think you talked me into it! I'll play with it tomorrow.
I've found this on Nook Color thread http://forum.xda-developers.com/showthread.php?t=888216
Can someone test is it worth to do on Archos? I think we don't need phone service running in background. Ill try this tomorrow when i get back to home but maybe someone can test earlier?
sorry for asking,but what is the point in doing step 3,i mean what does it actually do?
This is backup of install instruction, leaving more space for custom approach. Instruction in first post is now much simpler with less 'if/or'.
Material for this thread came from discussion here. So please be kind read also this thread before getting to work
This is mini how-to boot modified Archos Android from SD card, using SDE. It's base on 2.0.71.
Since this Android mod/distribution required some name - let it be Uruk-Droid
Why bother:
ext4 (much faster than ext3, can store files >4GB comparing to FAT32)
full r/w access to every part of system
root (su + superuser.apk) out of the box
possibility to remove some google/Archos apps (already done partly)
swap memory when you need it
no 300MB limit for apps (and no faulty app2sd required)
you can have SD card Class 8/10 - and that's much faster storage than internal flash (inside is something equal class 6 or 4)
Warning
Be aware that this modification requires SDE and probably some Linux knowledge.
By doing described below steps you probably can't brick your Archos - but do it on your own risk.
Root access on your devices makes it less secure form malicious software (user more head - less fingers )
Known problems:
Android automounter (vold) does not recognize EXT4 in stock firmware - so it will claim SD card is damaged (it's just a message) (FIXED)
Before you start:
Read about SDE on forum
Install some terminal emulator from Market (eg. "Android Terminal Emulator")
You should have 2.0.71 already installed (I'm not sure if it's required but only with that configuration tested)
All operations described here, done on Linux or Android should be done from root user (you can switch to that user in terminal by typing "su" or "sudo su" command)
If you don't have Linux - find any recent Rescue CD, Live CD or Virtual disk (VirtualBox or VMware) - distributions does not matter
SD card partition design
First of all, preferably buy card class 6+. So it won't be slower than internal storage
I'm currently using 3 partitions
0,5GB / (rootfs)
1GB /data
rest /mnt/storage/sdcard/
but You can create one big partition instead - I've made my configuration because of easiness to backup and upgrade (rootfs is easy to upgrade later on, /data has only runtime data and application, rest is for movies etc.) Size of /data partition determines how many apps you can install on your device.
Here it's how it looks on fdisk
Code:

/dev/sdb2 122 362 1055098 83 Linux
/dev/sdb3 363 3571 14049002 83 Linux
Step one
Create at least one primary partition on SD card with fdisk, gparted, parted or any other partitioning tool. Assuming your SDCARD is visible as /dev/sdb (on Linux box - check "dmesg").
Code:
su (go root)
fdisk /dev/sdb
fdisk options (it's interactive):
p (print existing partitions)
d n (delete partition by it's number 1,2,3 etc)
n (create partition, you will be asked about type (primary, secondary - go primary), number (give first available), start sector (just enter will set first possible), size (you can give it as +1M, +2G etc)
w (write all changes, until you give this command no changes are made on disk physically)
Format partitions as EXT4 - but without huge_file option (it won't work with this feature since it requires special kernel option that brakes compatibility with existing modules).
Code:
su (go root)
mkfs.ext4 -O ^huge_file /dev/sdb1
If you created more partitions - do those steps for everyone.
Code:
mkfs.ext4 -O ^huge_file /dev/sdb2
mkfs.ext4 -O ^huge_file /dev/sdb3
Kind of "session log" for this steps you can find in this post.
Step two
Extract content of rootfs.tar.gz onto first partition on SD card (it HAS to be first one). Do it from root account on Linux/UNI*X box - or you won't transfer all permissions properly (mainly +s on su/superuser.apk).
assuming your SD Card is visible under Linux as /dev/sdb (you can check it by typing "dmesg" after you connect it)
open terminal/shell - go root: su, or sudo su
create mount point: mkdir /tmp/sdcard
mount it (if it's not mounted already) for example: mount /dev/sdb1 /tmp/sdcard
go to /tmp/sdcard directory: cd /tmp/sdcard
extract rootfs: tar -zxf /path_to_file/rootfs.tar.gz
exit directory: cd
umount your card: umount /tmp/sdcard
Flash initramfs.gz and zImage from SDE boot menu:
reboot Archos70, hold up or down volume key until you see Recovery menu,
choose "Recovery System"->"Developer Edition Menu"->"Flash Kernel and Initramfs",
connect Archos to PC and copy initramfs.gz and zImage to device
Reboot and hold up or down volume, choose "Developer Edition".
You should see all yours apps etc. - it should look like your Archos , but with su/superuser.apk etc. (check it on terminal emulator by typing "su" and enter).
Before go to next step make sure you have booted to SDE system AND it has root access! (check "su" in terminal, run root explorer or titanium backup)
Step three
It's kind of optional - since you have already working system - but it's not fun yet
Now you should copy /data files onto SD card. Use terminal emulator (from market can be "Android Terminal Emulator") or sshd (QuickSSHd and log into your tablet) and do:
If you have ONE partition
Code:
su
cp -rp /data/* /data.new/
If two or more
Code:
su
mount -t ext4 /dev/block/mmcblk2p2 /data.new
cp -rp /data/* /data.new/
umount /data.new/
Poweroff device.
Step four
Put card into computer and:
one partion
remove /data
rename /data.new to /data
On Linux it may look like this:
Code:
su (or sometimes "sudo su")
mkdir /tmp/sdcard
mount /dev/sdb1 /tmp/sdcard
cd /tmp/sdcard
rm -rf data
mv data.new data
edit /init.rc (it's /init.rc on Android - on Linux box it's going to be something like /tmp/sdcard/init.rc) - use any editor to modify file - do it as a root!
Code:
su
vi /tmp/sdcard/init.rc (edit the file)
umount /tmp/sdcard/
What to edit:
Code:
# Comment this
# mount ext3 /dev/block/mmcblk0p4 /data noatime nosuid
# Uncomment this
# mount ext4 /dev/block/mmcblk2p2 /data noatime
mount ext3 /dev/block/mmcblk0p4 /data.old noatime nosuid
two or more partitions
edit /init.rc (it's /init.rc on Android - on Linux box it's going to be something like /tmp/sdcard/init.rc) - use any editor to modify file - do it as a root!
Code:
su (or sometimes "sudo su")
mkdir /tmp/sdcard
mount /dev/sdb1 /tmp/sdcard
cd /tmp/sdcard
vi init.rc (edit file)
umount /tmp/sdcard
What to edit:
Code:
# Comment this
# mount ext3 /dev/block/mmcblk0p4 /data noatime nosuid
# Uncomment this
mount ext4 /dev/block/mmcblk2p2 /data noatime
mount ext3 /dev/block/mmcblk0p4 /data.old noatime nosuid
If you have third partition on SDCARD, whether it's EXT4 (recommended) or FAT32 it should by automounted since 0.2 version.
Reboot - it should work
End
Stuff you can do later:
Vold - automount daemon on android is quit.... crappy - to let go message about "sd card damaged" edit /etc/vold.fstab and hash the line "dev_mount_lun volume_sdcard /mnt/storage/sdcard...."
Other partitions - if, by any reason, you have more partition on SD card (more then 3) you can also mount it putting in init.rc (there are some potential issues with vold to be solved)
for ext4
Code:
mount ext4 /dev/block/mmcblk2p5 /mnt/sdcard2 noatime nosuid
For fat32 partition preferably tweak with Vold config (/etc/vold.fstab) - or add something like this (in init.rc)
Code:
mount vfat /dev/block/mmcblk2p3 /mnt/sdcard2 uid=1000 gid=1015 fmask=0000 dmask=0000

Nm you said it's faster, interesting... I may test that out.
IMHO you should point out that it is a great security risk for having access to root without any password.
BTW this comment is not meant to insult you in anyway, but I think it is only fair to people that will use it and to cover your own ass.

Does this require a clean system to do the SDE Root? what happens to everything already installed etc.

There was already link to my write speed tests (now I've pasted it to second post) - read speed is about the same. In quadrant I have something about ~2300 (one of quadrants test is I/O benchmark) - but that's not my goal - so I don't care much about that kind of speed.

Of course your are right - but that's kind of obvious, and that's the reason why superuser.apk requires to specify what process can gain root access (I know it's not strong security - but better something than nothing)
Is there any way to do this on the a32, or can will there be a solution for the 32.
I had SDE installed before, but I used the uninstall developer edition option in the boot menu. Now, regardless of if I use the .aos file from archos that has SDE, whenever I reboot holding a volume button, I get to a menu that says "Archos A101IT Recovery", and "Would you like to recover your system?" with the following options:
No
Update Firmware
Repair System
Format System
I select update firmware, and all I get is an update failed error.
I don't know what to do. I have a basic linux knowledge, so I have my sd card properly formatted, without the huge file option. I've extracted the contents of rootfs.tar.gz to the first partition.
Any ideas on what to do?

I don't have that problem since I use Linux everywhere
My mmcblk2p3 is also EXT4 partition (since fat 32 has 4/2gb file size limitation it's only place where I can put bigger files - mainly movies. It's one of ther reasons why ext4 is good for the task).
To mount (vfat or ext4) during but of Archos put in init.rc
Code:
mount ext4 /dev/block/mmcblk2p3 /mnt/storage/sdcard noatime nosuid
or
mount vfat /dev/block/mmcblk2p3 /mnt/storage/sdcard
just after mount of /data.old for example..
/mnt/storage/sdcard is the place where automounter would normally mount this device.
Click to expand...
Click to collapse
I did try to add it to init.rc, but it wouldn't mount.
Running "busybox mount -t vfat /dev/block/mmcblk2p3 /mnt/storage/sdcard" after boot seems to work however.
Is /mnt/storage mounted yet at that point? It seems to be separately mounted ("mount" shows /dev/block/vold/179:9 mounted on /mnt/storage, but I can't find any line related to that in init.rc)
Since "Preparing internal storage" appears after boot, I assume the SD card has to be mounted after that (unless I mount it somewhere else, which would break compatibility with some apps)
Actually, I'd prefer if the SD card was mounted on /mnt/storage, and the internal storage on /mnt/storage/internal, is there a way to do that?
Edit: Ah, I checked that /etc/vold.fstab file. It seems to be what I need to edit to auto mount the SD card, but I'm not sure what I need to edit.
The line currently reads:
dev_mount_lun volume_sdcard /mnt/storage/sdcard auto /devices/platform/usb_mass_storage/lun1 /class/block/mmcblk2
"auto" seems to be the partition number, I tried to change this to different values as well as changing mmcblk2 to mmcblk2p3, but they result in the same SD card damaged message. Is this a no-go and just won't work or am I doing something wrong? Either way, it seems like it's the only way to mount the SD card at boot if I want it mounted to /mnt/storage/sdcard.
Edit 2:
Adding these 2 lines to init.rc and commenting out the equivalent lines in /etc/vold.fstab seems to work:
mount vfat /dev/block/mmcblk2p3 /mnt/storage
mount vfat /dev/block/mmcblk1p1 /mnt/storage/internal
Now I have the SD card mounted on /sdcard
However, the settings won't show the space information now, so I have to connect it to the PC to check free space. Is there a better way to do it?

No, this mount point (/mnt/storage/sdcard) is not ready yet at this point - that's why I've changed it to /mnt/sdcard2 in howto. It's not good solutions (since probably some tools won't find media - like movie player) - but the only one for now. Vold is crappy, and even so it should mount _first_ usable partition (with auto option) but it does not want to do that. I can't check it, since I don't have vfat on sdcard, but probably the only solution is to do separate script/service with delayed mount - that's what I'm going to do for now, later on (in next release).
Q: However, the settings won't show the space information now, so I have to connect it to the PC to check free space. Is there a better way to do it?
A: (kind of joke) - user "df -h" in terminal, probably some more smart tools with gui are also able to show space used by "other" devices.

I guess it's some Archos SDE bug and you should report it (I thing that after uninstall of SDE and second install you should see developer menu back - if not,
it's error or faulty "watermarking" at work)

My guess - it may also work for you. All gen8 devices have the same kernel and system - so give it a try.

Everything that is installed on INTERNAL 8GB storage is untouch. So even when sde fails to boot, you can go back to original Archos Android and work on that.
When you follow my instr. you should see second Android with all yours application installed but on ext4 with root etc. etc.

I think the error may lie in the fact that I have to access my sd card by mounting it through my a101. Tomorrow (or later today, rather) I will get a sd card reader so I won't have to rely on using the tablet.
Hi, thanks for howto.
Can we keep the superuser mode explained in this topic http://forum.xda-developers.com/showthread.php?t=880321&page=13 And use your method (in case i forgot m'y sd card And need root access)

If you now know basic "words of android world" you can take a look on really great tutorial how to root, install recovery and so on.
Have you some questions? Make sure that you look on Mihir287's FAQ
1. Basics of Unix-like system
su, root, rooting - what is it, why we need it
sh, bash, busybox - what BusyBox is, basic list of commands from BusyBox, bash, sh
Kernel - What is it?
su
Also referred as substitute user - is command for changing of the account in current terminal (usually black screen with blinking cursor). Default account is root account. So if you insert into terminal 'su' and hit enter, you will become root user.
root
Root alias superuser or poweruser is special user account for system administration. Similar to windows having its administrator account, unix-like system have system have the root. With this user you can do anything and if you will run command for delete whole system, unix will just do it! No asking, no confirming. So, watch your steps!
rooting
Rooting is just enabling power of root for applications or our proposes. You can read great article about Rooting on androidpolice. Kepp on your mind, that some steps described on this page are NOT compatible with our Optimus One!!
Superuser app
After rooting is done, you will see new app called superuser in app drawer. This app can delegate applications to use su (root) feature. When app ask for first use, popup window will appear asking if the application should be allowed to use root permission.
sh, bash
is a command-line interpreter or shell that provides a traditional user interface for the Unix operating system and for Unix-like systems. So simply, it is some interface, which can execute command(s), which you have entered. Many shells exist, but in scope of android you can (as far as I know) use only sh (standard - Bourne-shell) or bash (compiled in BusyBox or separately on XDA). Both are basically same, but bash has much more future and it is comfortable. It's too big to describe here, so if you are interested in learning more, follow links in sources section.
user/root shell
How do I know if I'm root or normal user? It's simple. Root's shell is ended with # (usually it's shell looks like "bash-3.2# _") and user's ends with $ (usually bash-3.2$ _). In terminal emulator you also can have only [path]($|#) (for root for example "/etc # _")
BusyBox
also called "The Swiss Army Knife of Embedded Linux" is a tool which brings into Android basic tools known from unix system, but is much more smaller than standard tools is. But this "packing" brings also limits in possibilities in comparison to standard tools in unix-system (missing special modes of tool, color output and so on). Many application use this. For example busybox grep (filtering of text) is needed for application called Market enabler.
BusyBox commands
list of commands is really wide, so it's not possible explain all, so I pickup only top few. (hint: if you want what some command do, just search on google for "man <command_name>" for example man mv or enter command here
cd - cange directory - same like in windows. You can switch directory. example: cd /sdcard
ls - list of files in actual directory (have few switches like for example: ls -l /sdcard/*.png (detailed listing)
cat - print file into standart output (like more in windows) Example: cat /sdcard/data.txt
vi - editing of file. But on limited phone keyboard (no keyboard) it is little harder Read more about vi
cp - copy of one or more file. Example: cp /sdcard/bike.jpg /sdcard/media/bike-wallpaper.jpg
mv - moving/rename files, Example: mv /sdcard/bike.jpg /sdcard/media/renamed-moved-bike.jpg
rm - delete file (rm -R for recursive, or for delete whole folder), Example: rm -R /sdcard/wallpaper-bad/*
find - search for files, Example find / -name "best-chopper-ever.avi"
mkdir - make directory - creates directory, Example: mkdir mynewdir
chmod - changes access of files
less - similar like cat, but you can scroll in it and it doesn't produce any output. Example: less /sdcard/funnytext.txt
Please, take due note that man pages are documentation of unix tools. For BusyBox's tool help, just enter BusyBox <command_name> -h.
Many time, when is BusyBox installed, are also symbolic links created. It means, that is not necessary do BusyBox <command>, but only <command> will be enough.

2. Android platform and it's specifics
adb shell - what is it, for what it is
Android SDK - what is it, tool which provides, where to download
Tools for work with Android adb shell - Terminal Emulator, ADB shell from Android SDK and how to use it
ADB (shell)
ADB - Android Debug Bridge is a versatile tool lets you manage the state of an emulator instance or Android-powered device. It is a client-server program that includes three components:
A client, which runs on your development machine. You can invoke a client from a shell by issuing an adb command. Other Android tools such as the ADT plugin and DDMS also create adb clients.
A server, which runs as a background process on your development machine. The server manages communication between the client and the adb daemon running on an emulator or device.
A daemon, which runs as a background process on each emulator or device instance.
Generally it can be compared with standard cmd prompt in windows (you can write commands which will be executed locally, for example in Terminal Emulator) or it can be just like SSH in unix-like system (you connect to terminal through adb client (in Android SDK) and commands will be run remotely.
Android SDK
Android software development kit is complex set of tools for developing app on Android. It includes fully usable emulator of Android OS on your PC, where you can do everything. You can install/delete apps, browse web page in embedded web browser, play games or make your own application in Eclipse (widely used IDE for development). Of course, with emulator you can use also GPS or camera. Emulated android phone is just like "normal" phone.

Tools for work with Android adb shell
You have two ways ho to connect into ADB service - locally and remotely.
Locally - for local access you will need some application which can connect to local adb shell.
Terminal Emulator (free) - probably most commonly used app from market, which works and looks like standard unix shell.
ConnectBot (free) - same as Terminal Emulator, but it can be also used for connecting via SSH or telnet
Remotelly- For remote connection you need phone configuration adjustment:
Home desktop -> [menu button] -> Settings -> Applications -> Development -> USB debugging [ON].
Also you need connect your phone via USB (or finds on market some widget/app, witch enable using ADB also via wi-fi)
adb tool from Android SDK
After download Android SDK, extract archive somewhere (in example I extracted it in c:/AndroidSDK). Then follow instruction on developer.android.com for installation of SDK Platform-tools (contains adb). After installation click on start menu and in Run... (in Windows7 in search bar) enter 'cmd' and press Ok or [enter]. Then write in cmd line:
Code:
cd c:\AndroidSDK\android-sdk-windows\tools [enter]
now you can enter following command to connect to phone's adb shell if you don't have more connected device (virtual or real-one)
Code:
adb shell
If you have more then one, you need explicitly say which one should be used for connection. So list connected devices with
Code:
adb devices
which shows you serial number of connected devices. Than use
Code:
adb -s <serial-number> shell

3. Custom recovery
What custom recovery is
Tools which custom recovery provide - NAND backup/restore, formatting of SDcard, partitioning (ext1,ext2, ext3), wiping, flashing of Custom ROM, ...
Is it save to install that? - potential problems, backup/restore of original recovery
How this whole thing works - installation description (not how-to install, just explanation of what is done during installation)
What custom recovery is
Recovery is image (binary data) stored in internal memory. This image contains something like "program" maybe better say "tool", which can boot-up independently on Android system. In other words, when this tool is running (booted up), than Android system is not. This tool is part of phone system, and in PC terminology recovery can by compared to BIOS with some added features. This recovery state can be reached on all phone, but if you don't have custom recovery, it will do so-called HW reset and automatically restart itself into standard boot mode. So what is difference between original recovery and custom recovery? Custom recovery didn't call master reset after start and also didn't restart itself.
Tools which custom recovery provides
Let's go check what custom recovery brings (I will describe Drellisdee's custom recovery so another recovery can brings another menu and tools)
In Drellisdee's post is picture of main screen with list and description of tools so let's look on it:
ADB as root user
what is root user, and what is adb, you should already know. If not, follow link on main post.
USB-MS Toggle :mounts sdcard as mass storage
It just mounts your phone as USB-mass storage (USB disk) so in PC you will see new disk where you can see folders based on mountes (lower) and were you can upload what you want.
Backup/Restore:
Nand Backup : runs a nandroid backup of data, cache, boot, system
Nand Backup + .android secure : backs up above plus .android_secure on sdcard (froyo native apps on sd)
//Native app which notify "application can be moved into SD card" if you can move some app. It's good to use, if you used it.
Nand + ext backup : data, cache, system, boot, plus apps2sd on ext partition (old style apps2sd)
//old style apps2sd is used on some custom ROM because can move every application into SD card instead of Froyo's apps2sd
Nand Restore : browse to and select nandroid backup to restore
Absolutely GREAT feature. With NAND you can do 1:1 copy (image) of your actual system (phone's memory). It means, that you didn't backup only SMS, contacts or apps, but whole system with all configuration, customization, wallpapers, system's tweaks... just everything - it creates image of whole phone system. This image will be written to your SD card which you are then free to copy around and back up on your computer.
What it means? You find custom ROM which looks awsome so you create NAND backup and install new ROM, but after few hour/days... you know, ROM before was better. So you boot into recovery, use NAND restore of your old ROM backup and .... woala you have your system just like before backup - as if nothing had happened. For about 2 minutes!! It sounds great, isn't? But one, little problem exist. You can not use for restore only some part of backup. You have to restore all, or nothing.
Flash Zip From Sdcard: Update.zip must be in root of sdcard
This tool is designed for install of custom ROM or for tweaks. If you have instruction to install via custom recovery, and file have .zip extension than you should use this menu. Never unzip file, because file contain meta-information about itself with some validate-checks so if you edit it, or unpack and pack back, it shouldn't work. And of course you can't select *.zip file if it doesn't exist because you unpack it, also you have not to rename it to update.zip, you can just select file to update in list of .zip files. And, at the end, file have to be in root (main folder) of sdcard.
Wipe Menu:
Wipe data/factory reset: wipes data & cache
- wipe of users data (contacts, apps, configuration, ...) and cache (caches of applications)
Wipe cache
- wipe cache only
Wipe Dalvik cache : Wipes Dalvik cache in all possible locations if moved by apps2sd
- wipe of Dalvik cache?
Wipe SD:ext : Wipes Apps2sd ext partition
- if you used Partition SDcard option, you can wipe it here
Wipe Battery Stats
- If you think, that your battery life is too short, you can try delete battery stats. Than let phone fully charge. (more)
Wipe rotate settings
- wipe senzor setting (acceleration, ...)
Wipe .android secure : Wipes froyo native .android_secure on sdcard
- wipe information about moved apps
Partition Sdcard:
Partition SD: Partition's sdcard for apps2sd (this formats card so all non backed-up data is lost)
- will create ext2 partition (you will be asked for size of ext2 and cache)
Repair Sd:ext
SD:ext2 to ext3 : coverts apps2sd ext2 partition to ext3 (requires kernel support for ext3)
SD:ext3 to ext4 : same as above but ext3 to ext4 (requires kernel support for ext4)
ext2 - file system for the Linux kernel (no journal, fast but not recovery of I/O error)
ext3 - file system for the Linux kernel (journal, slower than ext2 because of journal, but provides recovery on I/O error)
ext4 - file system for the Linux kernel (journal, enhanced version of ext3)

Is it save to install that?
Well, nothing isn't without any risk. Anyway, from what I know, nobody has had any problems, if Drellisdee's steps are followed, but you have to have P500, not derivate from Sprint, for example. From my point of view the installation of recovery is without any problems. After update with KDZ_FW_UPD tool I had rewritten also recovery. But this tool is really dangerous, so try to avoid to it.
Anyway, original recovery can be backuped before installation of custom recovery and this can be done by command
Code:
dd if=/dev/mtd/mtd2 of=/sdcard/<name-of-old-recovery>.img bs=4096
for example:
Code:
dd if=/dev/mtd/mtd2 of=/sdcard/my-original-recovery.img bs=4096
For restore,just use same step (command) that you used for flashing, but replace name of .img file.
Code:
flash_image recovery /sdcard/my-original-recovery.img
NOTE: You don't have to do other commands before and after as you done for install of recovery!!
So, where can problems arise?
loss of warranty - LG service have much more advanced software and hardware and they can check what problem caused - make dump of memory and so on
bricking of phone - if something goes wrong, then phone may not start at all
deletion of all data if installation fails - if old recovery remains, than hw reset will be performed
custom recovery doesn't work at all - incompatible devices
Why to try?
NAND backup/restore - the most useful tool ever
you can install custom ROM
high count of successful flashing of custom recovery
for now (what I read on forum), when you had said that you brick your phone by standard LG tool, your warranty repair was approved
How this whole thing works (description of installation's steps)
Let's see on how to:
Copy flash_image and recovery-RA-GNM-thunderg-1.1.0.img to the root of your sdcard
Nothing hard I think.
via adb shell or terminal type this from root su # shell. (Do not type the # as its just for reference to show you need a root # shell not a $ user shell)
Ok, it seems that it doesn't make sense, isn't. But what is root and su we already knows, same as user shell and root shell. Also follows commands probably aren't some "normal" task, so some special user approve will be necessary - so it probably means use of root. So, enter 'su [enter]' for become a root.
Code:
[B]# mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system[/B]
// remounting of filesystem for write
[B]# cat /sdcard/flash_image > /system/bin/flash_image[/B]
// print contend of flash_image into /system/bin/flash_image (it is just copying)
[B]# chmod 755 /system/bin/flash_image[/B]
// set up file access for running (basic of unix-like systems)
[B]# mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak[/B]
// rename install-recovery as install-recovery.sh.back
// NOTE: many guys haven't this file, so they get error: [I]"failed on '/system/etc/install-recovery.sh' - No such file or directory"[/I]
// it's normal. If it happens, just ignore it and continue.
[B]# mount -o remount,ro -t yaffs2 /dev/block/mtdblock1 /system[/B]
// remount of filesystem into read-only mode
[B]# flash_image recovery /sdcard/recovery-RA-GNM-thunderg-1.1.0.img[/B]
// using of program/script flash_image for flashing of recovery image
// you can do by same way also restore of your original recovery
[B]# reboot recovery[/B]
// reboots into recovery mode
I think, that was also nothing hard. As was said "#" on beginning means that root's shell should be used for running that command. Maybe you remember what I had written, that if you run something on root's account, it doesn't ask for confirmation and will just do it. Same with responses. If there is nothing to say, then nothing will be said. So if command runs without any problems, nothing will be shown. If something doesn't work, than you will be informed.
Key combo to boot custom recovery from powered off is vol_down + home + power and release keys at LG splash.
Nothing special I guess. But I recommend keep vol down + home keep pressed until custom ROM menu appear.
Note this recovery and the one for the LG Vortex have a service that instantly reboots out of recovery once you load it & I disabled it and thats why you get a E: "Bad Boot Message" on inital startup. Its completely fine.
IMPORTANT NOTE!! Too many of n00bs asking "I have problem, E: "Bad Boot Message appeared, what I should do?" Read ALL carefully before every action!!
Recovery Key mapping:
Up & down : vol-up and vol-down
Select : Menu
Backup : Back
Key map for moving in menu (touch screen doesn't work... )

Main topic
==========================
4. Custom ROM (generally)
What custom ROM is?
Is it save to install custom ROM? - potential problems
What I need for install?
What can custom ROM brings - kernel, update, performance, customization, theme, ....
what is ...
deodexed, zipaglined, png-optimized
JIT, HW:acceleration, VM.Heap Size, stagefright
apps2sd + dalvik2sd
custom kernel (recompiled, ...)
What custom ROM is?
Custom ROM is every somehow changed manufacturer's ROM or ROM compiled from source code of Android. "Change/s" can starts with adding/removing default application and can extend to kernels, cpu over/under-clocking, enable/disable features (ROOT, HW acceleration, ...), themes (frameworks, color, ...), keyboards and many other features.
Custom ROM is mostly distributed like signed ZIP package with included installation script for custom recovery. This ZIP is flashed via custom recovery tool.
Is it save to install custom ROM?
Yes, it is. May be I can say, that installation of custom ROM is almost mandatory, because it cost you only few minute if you will not be satisfied - you can just restore your old ROM from NAND backup, if you will be satisfied, you can keep it. And yes, you can also use backup tools like for example Astro for backup of your apps or Titanium Backup backup everything (SMS, call list, preferences, APNs, ...) and restore this in your new ROM (NOTE: In this case it's strongly recommended that both ROM should have same or very similar source/base ROM).
So, it is really simple:
1) Do NAND backup
2) Try new ROM
3) Keep new, or restore old one.
What I need for install?
1) Rooted phone
2) Installed custom recovery
3) Signed .ZIP file of ROM compatible with recovery
#) RECOMMENDED: NAND backup of your actual ROM
What does custom ROM bring
Custom ROM brings almost every feature you can image.
ex:
optimization for maximal power (games), long battery life, calling, texting, playing videos,...
awsome look - changed icons, colors, animations, wallpapers, menu, ....
simple work - feature that will short some work (add restart button, reorganized menu, shorts, gestures, ...)
allow tweaking - overclok/underclok your device, ROOT, ....
It's really not possible describe here every possibility what you can do/get with custom ROM.
what is ...
deodexed - needed for using themes. If you want replace/change some file in system (change theme) you need deodex file which you want change. In most cases it's going on services.jar which contains definition of colour for clock for example.
APKs zipaligned - optimization of APK archive, so it takes less memory and is much faster.
png-optimized - png files takes less memory, are loads faster
JIT - just-in-time compilation also known as dynamic translation, is a method to improve the runtime performance of computer programs, but it takes some time to convert into it on start.
HW:acceleration - using of HW acceleration for rendering GUI. Little increase battery consumption.
VM.Heap Size - maximum memory an application can consume
stagefright - In Android 2.2 new media framework that supports local file playback and HTTP progressive streaming
Apps2SD - (mostly DarkTremor's a2sd) If you create ext partition on your SD card, you can mount it like internal memory (you will have more space on phone memory) and move app on SD.
Dalvik2SD - move of Dalvik into SDcard (saves space)
custom kernel - compiled standard unix kernel (can bring support for features like support ext4 for example)

But you can be happy and proud, that you probably inspired me!
While backing up the old recovery what do you mean by:
recovery-dump-T
My first line went ok in terminal emulator but second line didn't go ok. That's why I am asking this.
Your the Man! Thank You So much! all are much clearer to me now! now lets gets things started!

mkcore - directory installation and swap file creation
-------------
What you need
-------------
Rooted Android Smartphone
Linux on PC
Busybox installed on your device
SDcard adapter or reader, if neccesary
----------
Lets begin
----------
There are 3 different ways you can do this:
1. Fresh install on EXT4 Sdcard partition ( I HIGHLY recommend this method if possible, much better, a bit faster (no double loops to write to)
2. Create Fresh .img
3. Replace old BT5 system .img
=========================================
1. Fresh install on EXT4 Sdcard Partition
=========================================
This portion of the guide is to install BT5 on a FRESH EXT4 partition on your SDcard. Throughout this porcess, you will:
Backup your current sdcard (EVERY PARTITION, this is why we use PC-linux and not windows)
Fully erase and repartition your SDcard
Replace Android system and user data
Install BT5 on third partition
prepare system for chroot and VNC connection
----------------------------------------
Boot into your Linux operating system. **I DO NOT recommend using virtualbox or vmware, as drivers for usb and SDcard connections arent direct, things can go wrong.**
Shutdown your phone, and remove your SDcard. Do not use adb, or any other tools to do this.
insert your SDcard into your computer (adapter or reader yada yada) and mount every partition.
Make careful note of what is on which partition. safest way to back everything up is through the command line with the command
Code:
sudo cp -Rfvp /media/your-sdcard-partition/* /where/your/backup/folder/is
Do this for each partition, whether you have 1, 2, 3, or more.
In my case, my backup directory looks like this:
Code:
[[email protected] sdcard-backup]$ ls -l
total 12
drwxrwxr-x. 2 hookup-cellular hookup-cellular 4096 Sep 13 18:48 ext2
drwxrwxr-x. 2 hookup-cellular hookup-cellular 4096 Sep 13 18:48 ext4
drwxrwxr-x. 2 hookup-cellular hookup-cellular 4096 Sep 13 18:48 fat32
(ignore the empty directory sizes, my TRUE backup folder is MUCH more vulgar and i wont display it publicly, people may tear thier eyes out )
After everything is backed up, open your partition manager (in Gnome it is gparted, cant remember the name in others)
Navigate to your SDcard, and DELETE every partition. every one.
afterwards, recreate them using this strategy:
partition 1 - FAT32 size = total sdcard size minus ext2 and ext4 partition sizes
partition 2 - EXT2 size = 256mb, 512mb, 1gb, depending on how you like your apps2sd
partition 3 - EXT4 size = size you want for linux, minimum should be 4gb (mines at 10gb, i like my linux and got 3 different ones on it at the same time.)
When you are done, copy back your fat32 and ext2 stuff using the SAME COMMAND AS ABOVE (sudo cp -Rfvp from/here to/here)
Now, unzip/tar the .tar.gz package. I recommend extracting it to your pc before trying to put it on your sdcard.
Using the copy command above, put the extracted files onto your sdcard's EXT4 partition.
Double check the partition (navigate to it in nautilus or whatever filemanager your using) and ensure that it has the system copied over properly. You should see /boot /etc /root /sys so on and so forth, NOT just one folder with all of those inside of it.
Insert your SDcard, power on your phone, go to terminal emulator, and enter this:
Code:
su
cd /sdcard/scripts
sh mkcore
Swap file is damn near neccessary if your planning on using any GUI tools (armitage, zenmap)
Your directory structure is now in place, swap file created, and you start BT5 by typing (from /sdcard/scripts OR /data/linux):
Code:
sh btgo
=================================
2. Fresh Image Creation
=================================
for this, we use the dd command and mkfs.ext4 command.
Code:
dd if=/dev/zero of=/path/to/where/you/want/the/img bs=1M count=3300
Change this command as needed, running it as is wont do anything good. Change the of= to where you want your img to be located.
next is mkfs.ext4
Code:
mkfs.ext4 /path/to/where/you/want/your/img
select yes when it cautions about "not a block device"
When this is finished, mount it using these commands:
Code:
su
-your password-
mkdir -p /mnt/bt5img
mount -t ext4 /path/to/your/img /mnt/bt5img
now, extract the BT5 package to a place on your Computer. When finished, run this command:
Code:
sudo cp -Rfvp /path/to/bt5/core/* /mnt/bt5img/
changing parameters accordingly.
After this, copy the .img to /sdcard/bt5 and run the start scripts from your terminal emulator.
================================
3. Replace Existing Image
================================
Mount your bt5 image, erase what is inside of it, and copy in the new system:
Code:
su
-your password-
mkdir -p /mnt/bt5img
mount -t (your ext type) -o loop /path/to/your/bt5/img /mnt/bt5img
rm -Rfv /mnt/bt5img/*
cp -Rfvp path/to/bt5/core/* /mnt/bt5img/
unmount your .img, place it on your sdcard, and your all set.
==============================
Changes in v0.3
==============================
- Trimmed alot of fat, fits inside of 3.3 image now, though space is SEVERLY limited (removed CUPS and sound stuff, who needs to print from within thier phone anyways?)
- various small changes for performace improvements.
- a few new tools installed, but not tested
- restored my personal version that i nuked. It works now.
NEW STUFF TO COME, STAY TUNED!!!
First off, My apologies for starting a second thread on this, I've made ALOT of changes and i feel the first thread is dead and useless. (Reprimand me if needed

========================
INFO
========================
This is my first release of a customized, working, mostly stable BT5.
Many things have been added, taken out, and configured to be used within the Android system. For a full list, please see the bottom of this post.
Mounting is different than most other linux .img installations, allowing for a full (and expandable) image.
V 0.2 Now has a swap file created when you run the mkdirectory script. This swap file is necessary, as with all my tests, When you run VNC with most of the major tools, there's a high chance of the phone running out of memory (im running no extra apps, completely stock Hyperdroid)
(if you have a swapfile already, you can say no to creating another, just make sure that the file is located at /data/bt and named btswap.)
**This image is in ext4, make sure your kernel supports it!**
**Everything tested on Hyperdroid-CM7 by pongster**
==============
INSTALLATION
==============
You need:
-Full Nandroid Backup in case something goes batty
-16gb HD2
-ext4 support on your ROM/kernel (lost my ext2 image due to my own stupidity, will create another matching one later)
-Linux on PC (to create the ext4 partition)
-Busybox (from market)
-VNC Viewer (from market) (optional)
FAT32/EXT4 Split card
---------------------
1.
Back up your HD2 and SDCard to safe places (off of the phone and sdcard)
2.
Boot your linux installation and open partition manager. erase all the partitions on yor SDcard. Then create them in this order.
1. FAT32 - size of this is total sdcard size minus 6.5g (for bt image) minus 100mb for aps2sd
2. ext2 - 100mb
3. ext4 - 6.5 gb
3.
Copy the bt5.img to the root of your third partition.
copy the bts folder to the root of your FAT32 partition.
4.
if this is your first time using this script/image, run the mkdirectory script first with
Code:
su
sh /pathtoscripts/mkdirectory
Load up your android terminal and type
Code:
su
cd /path/to/scripts
sh go
5.
Now it asks you if you want to log in to the console or start vnc automatically. (check log for port, usually 5901 or 5902)
DEFAULT VNC PASSWORD IS: toortoor
DEDICATED SDCARD
----------------
Same as everything above, minus the FAT32 partition.
"sh ded"
starts for dedicated SDcard instead of
"sh go"
Proper Shutdown Procedure
=====================
Stop script has been modified to shutdown backtrack and all of the (usual) programs that stop things from unmounting properly.
Exit any VNC connection you currently have.
1. Run sh stop (from your scripts location)
2. Reboot phone as a precaution.
One thing i did personally to make this easier was load the scripts onto /data/bt, so switching SDcards or locations doesnt matter.
(I also changed the terminal start directory to my scripts folder easy quick access)
=======================
Main Features I've gotten to work
=========================
-Clean mount/umount, as long as VNC and MySQL are killed BEFORE exiting the chroot - stop script kills these now
-Apps no longer disappear for good with sdcard removed, only disappear until SDcard is reinserted (apps2SD/loop device problem, any ideas?)
-MySQL for metasploit
-Metasploit working
-Armitage working, missing some "Attack" options (looking into it)
-Zenmap installed
-OpenVPN installed
-Traffic analysis possible with tcpdump (local only)
-Enables possibility for FakeAP attacks
-macchanger works (kinda, phone needs a reboot for original MAC to return)
-Armitage Launcher placed on Desktop (takes a while to load, be patient)
-Terminal Launchers in various places (updating may randomly remove your terminal, synaptic placed on desktop as standby to redownload terminals
-guake installed (drop down Terminal, makes commands easier to see while working) (not configured to a key yet)
This probably works with other Android phones too. If you change the scripts, and as long as it has a external SDcard you can partition.
if your using a different phone, this is untested unless specified otherwise.
-boot and shutdown scripts run clean as long as VNC and MySQL are shut off(in almost all cases)

Information, bugs, and oddities
===============================
One important thing, While performing heavy operations, its normal for your screen to not turn on for a while if it turns off. Dont panic, just give it some time to finish whatever you were running and your phone will be back to normal again. DO NOT PULL THE BATTERY UNLESS ABSOLUTELY NECESSARY.
To avoid this, get wakelock (known to cause problems) or set your screen timeout to some large number.
Swap file will help with alot of this.
These are the features I've tested out so far.
No major changes to anything, (except new packages) just configuring everything i see.
If you find anything you want added in or that is acting odd, please let me know. Same goes for if you fix something!!
Overall
-------
-Repo's activated, most things work (upstart processes fail, for now)
-startvnc and stopvnc no longer give that pesky USER error
-startvnc starts mysql database for metasploit
-stopvnc stops mysql (mostly, invoke ps -A and look for mysqld. Kill it with fire(-9) if need be)
-network traffic is capture-able with tcpdump, with wifi hotspot activated
-working on adding in a swap partition on sdcard (if possible)
-openoffice installed
-openVPN installed (the quieter you become...)
-Removed Zoho Web services
MySQL
-----
default user - root
default pass - toor
-Starts automatically with startvnc
-stops automatically with stopvnc
-start manually by invoking "mysqld"
-Only runs as root (for now)
-Console hangs when it is manually loaded or shutdown, service continues running though. killall --signal 9 mysqld if needed.
Metasploit
----------
-Loads up alright (45-90 seconds)
-MySQL already set as default DB
-Must manually connect to MySQL DB each instance of metasploit by invoking (from msf) db_connect root:[email protected]
-working on a possible way to limit cpu consumption to prevent system hangs(cpulimit does some nasty things)
-So far, this is the only connection string ive been able to get to work: root:[email protected]
Armitage
--------
-Takes forever to load (30 seconds for connect screen, 4 minutes or so for main client)
-Causes system hangs frequently (to minimize this, leave the vnc server on your screen, and set the display timeout to 10 minutes-switch it back when done to conserve battery life)
-So far, this is the only connection string ive been able to get to work: root:[email protected]
-Can Crash phone if running too big of an operation (Max Phone memory problem, fixed in v.2 with swapfile added)
Zenmap
------
-Slows phone down (incredibly bad with more complex scans, of course)
-Some Complex scanning options can crash phone (Nothing damaging has happened)
-will attempt to throttle cpu usage in the future
-Can Crash phone if running too big of an operation (Max Phone memory problem, fixed in v.2 with swapfile added)
Aircrack-ng suite
-----------------
-Aircrack-ng works
-Airodump-ng doesnt work (needs monitor)
-Airdecap-ng untested
-Airdecloak-ng untested
-Airbase-ng doesnt work (needs monitor)
-Airmon-ng doesnt work (needs monitor)
-Aireplay-ng doesnt work (needs monitor)
-Airdriver-ng doesnt work (yet)
-Airolib-ng works (doesnt do anything yet)
-Airserv-ng doesnt work (needs monitor)

Are you trying to patch the wifi drivers ? =D
Holy crap.....this is a dream in the making Bring on monitor mode and packet injection
I've done some researches.. and found out that many devs have tried making the driver to work on the Monitor mode.. but they failed to do that.
It looks to me that Backtrack on HD2 is kinda useless.
Not useless, just last night I ganked my roommates computer with my phone
As far as monitor mode and injection go, sadly, they may be right that its not possible, but I got some ideas that may make it work, I just need to hammer out some kinks in BT first
And who needs monitor when you can fakeAP?

Next release is going to be even better this 5gig image is almost full, so I'm going to expand it to 6gig, along with instructions on how to expand your own image if that's to large or want even more space.
Btw, Wine should be good to go in the next one
stay tuned!!

I would love to see some Sceenshots (or better: a video) here!
Lol will do, gotta go find my 10 year old Polaroid I've been using this phone or all my pics and videos, so this could be tricky

good to see development beyond just starting up the image... I would be taking some pointers from here for my device too....
hope you don't mind that....
Not at all, I've been trying to track down your name again so it can add you to the credits part, as the basis of the scripts was yours lol, I just changed the loops and mounting structures around a bit, and added some stability checks.
The scripts for this image are slightly out of date but I got new ones going up once I have time they should fix a few of the small eerrors people get while mounting
My next version is a little ways out (works gotten crazy busy lately) but it'll be out eventually

Hi Thank you for sharings this up!!! this is like a dream for alot of people.
i have followed all your steps but i have a problem when i run the scripts, the folders dont get created because when i run go i get a bounch of folder not found.
my SD card had some differences is a 16GB
with
Fat32
Ext-sd/ EXT2 -->1GB
EXT3 --> 100MB
EXT4 --> 6.5GB
could this setup causing the script to look on the wrong partitions? i have alot of time with out playing with Shell scripting but i would like to know if that is the place i should start looking for a fix
-edit- just double checked (forgot scripts were on my phone... its been a long week lol) and you should just need to change the mount -t ext4 /dev/block/vold/179:3 to /dev/block/vold/179:4
Also, did you run the new mkdirectory script? If you have the one packaged with the image its out of date. The attachment on the fist post has the updated ones
Ignore all mmcblk's
For another "buffer" partition, you need t point the sdcard parts (mmcblk0p* and vold/179:*) to what yours are in /dev/block. In your case I think you just need to change any vold/179:3 to 179:4. If you go to /dev/block/vold it will have folders from each partition (they are numbered 0 and up, but 1 would be your fat32, 2 is ext2 so on and so forth)
When I'm near my computer ill figure out the full ones for you
Sent from my HD2 Pocket Laptop
can I get it for Htc desire..??
It should work, as long as you have a big enough sdcard, your phomes kernel suppers ext4, and you might have to change a few small variables

DISCLAIMER!
Operations on phone’s partition could be EXTREMALY dangerous.
As You surely expect - I take no resposibility if something will go... not as it supposed to. The responsibility for potential damages caused by using this guide is Yours, and Yours only!
New system partition scheme is “designed” for custom ROMs NOT based on original Samsung firmwares (because of it’s size and using /preload partition, which we intend to extremely resize), to name just a few reasons).​
The method of modification is created by @Tesla-MADAL93 from Galaxy Advance sub-forum, all credits should go to him!!! He spend many hours using trials and errors method to achieve final success.
Part ONE: Preparations / theory.
1.Procedure requires any Linux distro with usb connection configured (tested on Ubuntu 12.04 LTS).
2.Working ADB (android debug bridge) – you don’t need to install whole ADK, just adb file with correct path added.
[EDIT/CAUTION]You can use Windows with adb configured, as proven by @maxprzemo, but I wasn’t tested by author of this guide!
3.It is strongly recommended to make a backup of your apps and data before start (using titanium backup or simipar app) Restoring nandroid backup will destroy your new partitions, so don’t use it!!!
4.With this method “safe partiotions” of phone’s eMMC memory are being removed and recreated „safe” using „parted” command in adb shell mode. Some partitions are extremely decreased, one is totally deleted. And the most important – partition of your choice will be expanded. Example displayed below sets internal (DATA) partition as large as possible (almost).
5.You will need external micro SD card after remodelling partitions)
6.Memory swap (SD0 and SD1) required BEFORE first start of your chosen ROM!!!
7.You can restore original partition scheme using Heimdall or Odin (not tested by me, problems with Odin reported by the author of whole modification) with repartition selected.
8.Partition numbers and names are very important (crucial), so we need to create them correctly, setting beginning and the end of each one very carefully.
9.Last important thing! I use minimal gapps pack for every ROM. I didn’t tested if full gapss fit on new /system partition! You’ll have to check it by yourself!
Default partitions and sizes are displayed here:
​With this guide you will achieve something like this:
[Side Note: this is just an example – you can make internal card (UMS partition) bigger, leaving /DATA partition intact, just to install bigger games – you’ll have to calculate your own values]
Part TWO: Repartition
OK., let’s do it! You have to perform all steps EXACTLY in described order!
1.Turn phone on in recovery mode, connect it to computer using usb cable.
2.Open terminal / console (Ctrl+Alt+T)
2a. Enter command:
Code:
adb devices
You should see device connected (some numbers and letters)
3.Write (press enter after each command):
Code:
adb shell
su
parted /dev/block/mmcblk0
unit kb
print
You should see default partition scheme (just as one first screen above)
OK., say goodbye to your old partitions. Deleting other partitions could (and probably – will) have irreversible consequences!!
Now we will delete partitions, starting from the last one:
Code:
rm 8
rm 11
rm 9
rm 4
Now you will encounter some error – despite of the unmounting partitions before abovementioned procedure - /cache partition is now mounted. Do not unplug phone, just enter “mount and storage” submenu in recovery, and unmount cache partition)
So let’s continue:
Code:
rm 4
rm 5
rm 3
You just deleted all “safe” partitions, enter to check this:
Code:
print
OK., it’s time to (re)create!
(SYSTEM, partition 3)
Code:
mkpart primary 105906 525906
(CACHEFS, partition 4)
Code:
mkpart primary 3848809 3948809
(DATAFS, partition 5)
Code:
mkpart primary 525906 3848809
(UMS, partition 8)
Code:
mkpart primary 3948873 3948937
(HIDDEN, partition 9)
Code:
mkpart primary 3948809 3948873
Let’s rename them properly (probably you can do it in one mkpart command, but it doesn’t matter):
Code:
name 3 SYSTEM
name 4 CACHEFS
name 5 DATAFS
name 8 UMS
name 9 HIDDEN
Almost done, let’s check:
Code:
print
Nice? Of course it’s nice!!! )
One last thing – we have to make our magic /preload (HIDDEN) partition visible for phone [it won’t boot without it!!] Because recovery won’t format it properly, lets use parted command for a last time (wait after each command):
Code:
mkfs
y
9
ext2
Now you can unplug the phone and format (in recovery) partitions:
/system
/data
/cache
OK, as I said before – you’ll have to switch storages BEFORE using phone again.
For now – you will have to manage it by yourself, just to make it short:
-for 4.2.x ROMs you can use modified vold.fstab file
-for 4.3.x ROMs – you have to manually modify build.prop, or use available zip package that will do it for you (that method is supposed to work with 4.2.x ROMs, but I didn’t test it!)
-I never used any of 4.4.x ROMs, but as I heard, there is method for switching memories too.
WARNING!
I didn’t test the way back to original partition sizes! It was tested by tesla-Madal93 though…
Sometimes (when transfer ring from one android version ROM to other, or using some old version where /preload partition was set as SWAP) you will need manualny format HIDDEN partition, just as shown above:
in adb shell mode:
Code:
parted /dev/block/mmcblk0
Code:
mkfs
y
9
ext2
FINAL WORD: If you are not sure – DON’T DO IT!!!
Screenshots are broken... I assume this deletes the "USB storage"? If then, you and the OP are bosses :good:
I can see the pictures (but are linked from other forum, i'll switch them in future), but yes - it deletes usb storage (ok, not really - new usb storage has 64KB and doesn't have to be even formatted)
Good job !:good:
Personaly i wont do it ever because 1,2 GB is enough, and if i get over that surely i have something on phone that i need to delete because i am not using it
Great post.
I would love to see the same mkpart commands to recover the preload partition space and allocate it to the data partition.
I'll do the full repartitioning thing when the team canjica CM11 major bugs have been solved. I'm not too confident about the other cm11's memory swap sustainability over time

I don't know if I can make something as a simple script for recovery (maybe with busybox), but for Linux yes (to automate repartition process). In every case, I will tell/send it to @judas1977 that will provide to update this guide.

Well done judas77 and Tesla-MADAL93 :laugh:
I'll try to make (semi)automate script for linux terminal in couple of days (unless @Tesla-MADAL93 make this) - then we can have/prepare separate scripts for various partition sizes:
- bigger /DATA
- bigger /UMS (like @maxprzemo did)

/data 350M (assuming about 100M of actual usable app space) (20MB margin) -- in practice less than 600 will be quite tight
/sdcard 1M (depends on apps again and FAT fragments easily by design, avoid less than 100M)
Now what should be nice having are ROM variants with internal storage disabled, so that we can remove partition 8 and both bypass the need for storage swapping but also avoid some apps not desiged for 2 "SDs" getting partially broken
I just repartitioned my phone, but acidentally I partitioned partition 2 instead of 3 :/
Now when I try to rename the partition 2 again in "Modem FS" with the name command, it only names the partition as "Modem". Can someone explain me please how to rename it to the original name again?
Thank you

I restored my old nv_backup and now the device is booting... Let's see if it will work. I'm just confused, because in recovery the partition is called modemfs and when restoring nv backup it is called Modemfs....

Impossible (well, without LVM or something) because there's USB storage in the middle... but with 10 minutes and a calculator you can create your partition sizes relatively easily
If I'll make the following changes in partitions: UMS resize to 400MB, CACHEFS resize to 30MB, DATAFS resize to 2,313GB, Fota 0 MB and I'll leave SYSTEM and HIDDEN to default sizes can I restore CWM Recovery backup or flash stock rom with Odin?
The HIDDEN partition will have the same size, but the location on mmc is different, as you can see below.

And be sure to input the partitions in numerical order!
You can make a script? For linux and winzozz?

Don't make CACHEFS partition under a minimum 100 MB!!!
In this partition is stored system apps' dalvik cache on all CM and CM-based ROMs, if available space is insufficient to store dalvik cache of all system apps the ROM isn't stable and has lot of FCs depending on what caches are not stored. If you want to go under 100 MB (that I advice) first check actual used space on this partition with Partition Table (available on Play Store) on your ROM, remember that every ROM has its system-dalvik cache size depending from apps' classes.dex

And why?
I've had zero problems in Android with 10 MB as long as you keep dalvik-cache away from it ( dalvik.vm.dexopt-data-only=1 and …cache-only=0)
Recovery probably uses it more though...

[RECOVERY][DUALBOOT][MAGISK][3.3.1-79][Unified]Unofficial TWRP for OnePlus 7/7 Pro/5G

If you want to make something like this for your device, check out this guide here
Since I no longer have an OP 7 series device, this mod is now deprecated and won't be receiving any more updates. @invernomut0 has made a continuation of this mod using orangefox recovery. Check it out here!
Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.
Code:
#include <std_disclaimer.h>
/*
*
* We are not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at us for messing up your device, we will laugh at you.
*
*/
Compatibility
This has only been tested by me on Oxygen OS Stable - Android Q.
Disclaimer
This is a DANGEROUS mod. Anything involving repartitioning is. If you fail to read and bad things happen, that's on you. Although I thoroughly tested this (managed to brick my phone once), there's always the possibility that something could go wrong with the worst case scenario resulting in a brick.
YOU'VE BEEN WARNED - Use at your own risk
What is this?
This is @mauronofrio's TWRP (see official thread here) that's been modified for true dual booting by splitting userdata into a/b slots (also does the same for metadata for encryption support). The installer script repartitions userdata for dualboot or stock based on your input.
Limitations
See the section in the github readme. MAKE SURE YOU READ THIS!
Features:
Same as mauronofrio's TWRP
Can choose between stock layout, a/b userdata, or a/b/c userdata where 'c' is a common data partition that'll show up in both roms - it's quite handy
Option to choose between ext4 and f2fs
Disables verity - fstabs are modified for dual boot and so this is a must unless you choose stock layout in which case it's optional
Option to disable forced encryption
Option to install magisk
Common Data
I recommend the a/b/c layout which includes this common data partition
If you choose a/b/c layout - you'll have a/b userdata, but you'll also get a 3rd userdata partition I call 'Common Data'
The name 'Common Data' gives away its purpose - to store files that you'll access on both slots/roms. So stuff like zips, pictures, music, TWRP backups, etc.
In TWRP, this shows up as another storage option for backup/restore and on your pc as well - your phone will have 'Common Storage' and 'Internal Storage'
In order to be accessible when booted, some parts of the system are modified so that the it'll be accessible WITHOUT root by the following mechanisms:
- The common data partition is mounted to /sdcard/CommonData
- .nomedia file is placed in CommonData so files in it won't be picked up twice if you decide to mount over internal storage as outlined below
- Furthermore, if your use case is like mine where my music files are in common data, you can make 'mounts.txt' file in /datacommon containing a list of every FOLDER to mount directly over top of sdcard. So for example:
/datacommon/Music -> /sdcard/Music
+ This of course mounts over anything there (overwrites it for as long as it's mounted) so make sure that you don't have the same folder in both datacommon and regular data
+ Note that there are 3 exceptions to this folder mounting rule:
1) All - if this is the FIRST line, ALL folders in datacommon will be mounted
2 )Android
3) lost+found
+ The reasoning should be obvious - lost+found isn't something you should need to mess with and Android is for regular data partition only - that's OS specific and should be on separate slots
+ Note that you should have 1 folder listed on every line, for example:
Code:
DCIM
Music
Pictures
ViPER4AndroidFX
Flashing Instructions
You MUST be booted into TWRP already when flashing this zip. You can grab a bootable twrp img from here
Since this modifies data - the zip CANNOT be on sdcard or data at all UNLESS you do not want to repartition/format
- If you flash from data, the zip will copy itself to /tmp and instruct you to flash it from there OR you can just install twrp/magisk/disver-fec
- You could do the above or copy it to a place like /dev or /tmp and flash it from there
- Alternatively, you can adb sideload it
Read through ALL the prompts - there's lots of options
Note that if you change partition layout, THIS WILL WIPE ALL DATA INCLUDING INTERNAL STORAGE
How to Flash Roms - If you're NOT stock layout
Nothing changes here except ONLY FLASH IN TWRP
- Roms always flash to the opposite slot. Keep that in mind and you'll be fine
- So don't take an OTA while booted - boot into twrp, switch slots, reboot into twrp, flash rom
Normal flash procedure:
1) Boot into twrp
2) reboot into twrp selecting slot you do NOT want rom installed to
3) Flash rom
4) Flash this zip
5) Reboot into twrp
6) Flash everything else
Help! I Can't Boot!
Usually this is because you switched roms without formatting data first. This should be flashing 101 but we all forget sometimes. Plus this slot stuff can get confusing
If it only happens with a/b/c and not any other layout, there's a good chance it's selinux related. Try setting selinux to permissive at kernel level with this mod(source here). If this doesn't fix it, it could be because selinux can't be set to enforcing even with the mod depending on the rom
How to Manually Repartition Back to Stock
In the event any step in the repartioning fails, the entire installer aborts. The good news is that this prevents a potential brick. The bad is that you need to manually revert back. See the README on github for the procedure. Note that if the install went fine and you want to switch back to stock later, just flash the installer again and choose stock layout

Ya. You can have a different rom on each slot
Will it impact on my original data partition if I flashed this TWRP.( I means whether my original data being splitted into 2-individual-parition + 1-common-partition and I need to reinstall my data after entering system ?)

The installer will tell you if it'll wipe internal storage or not.
Basically, if you choose to change the partition layout, data will all be wiped since it'll be repartitioned. If you choose to keep your partition layout at the beginning of the install, your data will be fine.
You could just use this zip as twrp, magisk, verity/fec modifer/installer to save you the extra steps and keep with stock layout
This is super cool. Will be testing soon. Just to confirm, this means I can have a custom rom on one slot and oxygen os on the other? Also f2fs should work fine with common data right?

Yup. You can do whatever you want with either slot. This mod formats all data partitions as ext4 since that's what oneplus does. You can always reformat userdata to f2fs in twrp gui later if you want though. Same goes for common data although I don't think there's a gui option for that
How does this zip to allocate the each size of userdata ? Can be customized by ourself or automated by zip itself ?

From what I see it can not be customized through the flasher (may be possible by editing values in the zip). In case you were wondering the size of the partitions, they are 96.7gb for the common storage and 62.4gb each for the individual storages.

It's automated by installer. If you have a 128gb device:
32gb for each userdata slot, commondata gets what's left
256gb device:
Everything's doubled from above

What commands do I need to fix this. I can still get into adb shell
edit: msmtool cannot restore from this because the partitions are not correct from the way it looks when I try it. when in recovery touch does not work.

Thank you for this work I have screwed up all of my partitions on my Oneplus and could use a pointer on how to restore all of the correct partitions... :-0
I must have screwed up one of the commands on restoring my original partitions here is what I have now
C:\Users\The Family>adb shell
OnePlus7Pro:/ # sgdisk /dev/block/sda --print
Creating new GPT entries.

I have the steps outlined here: https://github.com/Zackptg5/TWRP-DualBoot-Guac-Unified/#how-to-manually-repartition-back-to-stock
But what did you do? It looks like you formatted all of /dev/block/sda which is essentially a brick. You are able to restore that with msmtool btw but there will still be some device specific data that is lost and you'll likely need to file warranty claim

It was this step that I really messed up
Final step is to format the new userdata partition: mke2fs -t ext4 -b 4096 /dev/block/sda$userdata_num $userdata_size - where userdata_size can be calculated with this shell command: sgdisk /dev/block/sda --print | grep "^ *$userdata_num" | awk '{print $3-$2+1}'
with this step I used the result from sgdisk /dev/block/sda --print | grep "^ *$userdata_num" | awk '{print $3-$2+1}' I do not remember the value into the spot where userdata_size was
It looks like have been able to flash partitions manually in fastboot but the two partitions that are no longer recognized are the system_a and system_b the reason I say that is because vendor and boot flash fine on both a and b partitions. and when I send the commands to flash system a or b the reply is partition not found?! I am not sure if it would fix my problem but if I could get help to restore system partitions maybe I can get this thing to boot up.

The formatting steps is how I initially bricked my phone when I was figuring this stuff out - I since fixed that issue and made sure it'd never happen again in the zip :/
Why were you manually restoring? Did the zip cut off with partition error?
You'll need to use msmtool in this case. Even if your partition block is completely toast, it's able to bring it all back. You can grab the latest one from here: https://androidfilehost.com/?w=files&flid=296306
And here's the guide for it: https://forum.xda-developers.com/oneplus-7-pro/how-to/msm-tool-guac-t3934691

When I run the latest 10.4 global I get "device does not match image" and then under status I loose connection. I have also tried the 10.31 file with no luck either.

In msmtool? Do you have the right variant?
Latest global: https://androidfilehost.com/?fid=4349826312261732245
Latest europe: https://androidfilehost.com/?fid=4349826312261732244
Download mode is really tricky too. It times out after several seconds so you pretty much have to keep holding down the key combo until msmtool picks it up and then you can release them

Sounds like you may need to file a warranty claim then :/
