Hi,
Just wondering if/when MadCatz will release the kernel?
I know linux being GPL, it has to be shared, but not sure about Nvidia's sources?
I'm new to android but not java(my day job) and linux.
I've compiled and installed my own kernels on desktop and on my mobile phone (Nokia N900).
I want to try and add a few things.. ie filesystem/DVB/webcam support etc.
Following this how to.
Apologies for the delay in getting this released. Here's the kernel source:
ftp://86.54.116.234/pub/software/mojo/firmware/mojo-jb-kernel.tar.gz

Sweet! many thanks :victory:
:highfive:
:good:
omg.... does this mean we can finally have a cifs module!? AWESOME!
So now that the kernel source is avialable, I'm looking forward to the first custom kernels. Would be great to have some kernel optimizations and other tweaks built in :good:

Yes i hope someone can make a kernel to re-apply resolution settings on the m.o.j.o, as mad catz said to me via a phone call some tv's can't adjust to 1080p natively because the os is preventing it,and stupidly they removed the resolution changing slider in settings don't ask me why they did that?
If there is a way to set resolution without endangering the console booting up afterwards would be awesome,i am thinking it is there but hidden away and accessable some way but don't know how,developer options can be opened but not resolution settings as far as i have found any way.

I think it automatically sets the resolution based on the TV/monitor, try a different one?
TMK, the slider has nothing to do with the kernel.

I would do that but i only have a panasonic 50" plasma it's a 600hz 1080p it p50x50b model,there are 2 variants of it a hd ready and a 1080p model,i know it's the 1080p model as i used blu ray and xbox 360 and a wiiu etc in 1080p modes so it's definately not 720p only on my model.
I still think it is possible to reinstate that hdmi resolution slider though? I would love for someone to find a fix for that to bring back the slider though.
It also has nothing to do with the overscan as that's off,and the guy said it's an argument between the console's os and the tv,but maybe if i had an option to change resolution within the console when in operation it would ammend this,resolution changer pro works then looses usability eventually and it's awkward and time consuming to get that to work,only for it to stop after a time?
There is no forced hdmi resolution setting in the tv menu unless of course there is in engineer mode but all that seems to do when entered is show test and it's results coming up as ok,after testing it factory resets the tv as well so sick of trying that now.
Someone needs to get a custom rom made up with kitkat and 1080p natively set.

Unable to untar the tar.gz file. It says "tar: kernel/drivers/net/wireless/bcm43341/src/include/proto/p2p.h: Cannot open: Not a directory" and there are many lines like this. Tried everything from sudo, sudo -s, chmod, chown....
Also it says cannot mkdir: is not a directory
Its a .h and .c files ofcourse they aren't directories! Its not letting me execute make without errors since my source is like crap crawling with this "NOT A DIRECTORY"
Nothing is working. Command used was tar xvfz mojo-jb-kernel.tar.gz with many combinations and OS is Ubuntu 12.04 LTS 64 bit...

Hey,
I suggest downloading with wget or a good download/ftp application if it's timeout on you.
It's not corrupted, it worked for me and the date stamp is still the same.

It doesn't time out but it says some .c and .h cannot open: Not a directory when I use tar to extract it. Then I thought that I should install something else to extract and tried ARC. It extracted and then the same message box as appeared in windows 7 OS "file already exists cancel or overwrite"
I then said overwrite and then I get the extracted package. I just want to ask you that when you extracted it did you got any errors? What procedure you used to extract it? I downloaded twice with same results...

OK as per your suggestion I used wget c and the address. That gave me again the same file and upon extracting it I am getting same errors.
May be that the file isn't corrupted as you can extract it and its possible that I am doing something wrong in extraction..
I tried to create the kernel from sources and got a make error, to remove that I must delete a line in the make file (Line no 603) and after that I can successfully compile the zimage. But the issue is that after completing the procedure for boot.img file the original and compiled one has a difference of 0.1 MB and device don't boot with the newly compiled boot.img
Please if you can provide me with the steps on how you exctracted it and which OS you are using?then it will be really helpful. Also can you please upload the makefile of kernel and config.gz file you are using to make the kernel...
One useful information that can prove that there is an issue in extraction:
Extracted content on windows OS with Administrator priviledges: 42889 items , 487.8 MB
Extracted content on Ubuntu with Tar and other utilities: 42692 items, 482.5 MB

Seems like you are the only person who can help me as no one else seems to be active on MOJO development department. Sorry to disturb you again friend but you know I tried extracting on Android too and it failed there too!
I am completely exhaused with two days 24hrs of searching only extraction process. Please let me know if you successfully compiled and booted the kernel on your MOJO. If yes then I need more information from you as I had compiled the kernel but as I told you earlier it didn't worked... Please reply ASAP

Hi,
I'm in Aust. so there's a time difference.
I'm also about to leave on a 4week holiday and don't have my mojo dev stuff on my laptop.
I just used tar -vxzf filename
I think the only errors were a bad lsymbolic links which arent required.. from memory I could be wrong.
If you read the other threads here, I and someone else explain how we got the kernel compiled and yes it works fine.
http://forum.xda-developers.com/showthread.php?t=2691985&page=2
You dont use their makefile you recreate it .
If this is your first linux kernel or even android kernel, it's a tricky process and it takes time research all the steps.
Good luck

I have gone through with the links you provided already and I understand every bit of conversation. Yes I am new to kernel compiling but its reasonably understandable.
I respect your valuable answer no matter when you reply since you have a minute for me and don't worry about TimeZone differences as I am not in a great hurry, I just don't wish to waste time on errors for which I ain't responsible
OK I tried compiling modules for which I had to compile the kernel to get the module.symvar file and "THE MODULES WORK!" that too with the Default kernel Makefile and ofcourse my own module Makefile.
"You dont use their makefile you recreate it" this line you wrote.. What do you mean by that??
I mean were you talking about the kernel Makefile or our own module Makefile, Please clear me here? As far as I know the Kernel Makefile should be the same when only compiling the stock kernel as that is my purpose "JUST TO COMPILE THE STOCK KERNEL"...
My compiled kernel boots but just shows a black screen! I don't want to spoil your holidays sincerely but if some help I can get from you then I will be able to relieve me from this burden
Hmm got it compiled finally even after that make issue with -k flag to make
Also all I needed was ramdisk from latest OTA and not the one from the kernel. That was the issue with kernel booting but it freezing at blank screen...
RESOLVED :highfive:

Glad you got it working.
Re the makefile, I think you have to run config first to check your systems compilers/linkers/etc which then creates the makefile.

is there any reason this is done via some random ftp server and not some place like github/bitbucket with better management? or heck even sourceforge would be an improvement.
is that account for developer outreach? are there any datasheets on the components used in the device? sony does a beta program for updates on their flagship devices have you considered doing something similar where people can grab images and help test updates? ever think about tossing the device trees up for aosp to help encourage a porting of 3rd party roms and spread the community?
the nook color and touchpad being hack and having Cyanogenmod and the like being ported to it drove sales up, i would imagine having a hackable android console that isnt some no name chinese brand would probably do decent. unfortunately now with android tv you guys have some serious competition on the horizon, its a matter of how you go from here and try to make the most of it so everyone already has your product and doesnt need another.
edit: i also see there is several updates yet only one kernel source... any chance of updated source?
@Mad Catz Rich
The new update (205-TS) has a new kernel build of May 2nd.
Any chance that can be put on the server?

Excellent initiative, I could write a short howto for Arch Linux later.
But one thing though, it might be a good idea to mention in the first post that you can't actually boot a custom kernel yet.

Your thread is excellent but I'd guess that this thread would be more oriented towards "hand-holding", really basic guides. Your topic was very broad requiring going to the android developers site and reading their docs on cross-compilation. Gathering that info into easier guides could be beneficial, if not to demystify the process.
As it stands right now just compiling modules seems almost insurmountable. But if the information needed could be condensed into simple guides it could show that while it takes considerable time and effort it's not an impossible task even for developers not familiar with cross-compiling kernels.
And information information on setting up cross-compilers for Win, Mac and popular Linux distros is nice to have available in an easy to find topic anyway.
IMHO, the easiest way to make modules would be a virtualbox image already set up with arm gcc, kernel sources and X10 kernel config. It's a long process to set everything up; virtualbox makes this easier and cross platform.

Ok i managed to make Ubuntu on my Parallels, just finished with the gcc. Let's see how it works.

Hi zdzihu,
I managed somehow install arm gcc on my Ubuntu. Now it's time for the tools.
So i would like to ask what config should i use arm v4? V5?
I am so tired with this linux things, but finally at least the demo busybox compiled well
So i tried to compile with arm-v5te config but for flash read (which is normaly working) it says
Code:
# ./dump_image system /sdcard/tt.bin
error reading system: Inappropriate ioctl for device
My task it not to run flash tools available, but my own, to compile all myself, to try to do the trick with the CPU to accept kernel, that i compiled.
Thanks.
The Snapdragon is armv7 compliant, so that should be your target.

Are you using that tool to build the toolchain? In that case it might not have the option to build for that arch. The best way to make sure you get the correct one is to build it manually from scratch.

Looks like there is no other tut to build the toolchain. I searched days and nights to find something working.
I even compiled bysybox with it and it works on my x10!
But i found some sources of flash backup, called nandtools, compiled them well, no errors but the exec files are 4x bigger than the precompiled ones... And it makes the IOControl error..
the NDK won't compile, it requires Makefile or Android.mk and those are real headache to learn.
The Makefile from the archive is not compatible with NDK's make system and so on...
And so 2 weeks..
Pufff.. I am so tired if just linux things
Any hand?
Hi there, ARM is backward compatibile so compiled for v5 should run just fine. Problem must be somewhere else... I'm at work at the moment so I can't help much
By the way, there was some kind of dedicated flash tool posted already HERE, maybe you could check with jerpelea for re-upload?

You see, i need to compile mine, i have enough tools here already working, but my task is to compile my own and that's why i need a toolchain.
NDK is ok for the kernel, i compiled it already. But the native applications are not supported fully. Like write is deprecated and you can't use this function, and lot other limitations. So independent toolchain would help.
That's the point.

Will this actually boot and run? If it's that "easy", then why don't more devices have ICS? If you can extract the binaries and cook up a rom, I would be happy to test it . Also, if I have time later this week, I'll try to follow those instructions and then post my results. If everything works on the first try, I'll be very surprised but not at all dissapointed .

Well maybe because people don't know how to do it. And as for the current rom the major problem is the hardware acceleration and the camera. Maybe We can find it (The binairies) at opensource.samsung.com
It should be easier than phones because you don't have to worry about not screwing with voice, data, and stuff like that. Just get it on and get all the apps working correctly. Radios are always the hardest.
I've also been triyng to compile the source for the player but i wasnt able to do so, the thing is that the source compiles fine with the pre-adjustments it comes with, i mean the androidboard.mk ( i think thats the name of the file not sure), but when i changed the variables for a armv5 build, which is the core of the device and the ones that comes in the same file on the opensource.samsung soource, it just doesnt compile and throws some kind of errors about some libraries that i didnt touched. i dont know what i had been doing wrong.
I Also found this video in which they show whats in every folder, and how to build and add packages from source to the build:
http://marakana.com/forums/android/general/269.html
This is a detail process description from the official android site to build from source, very similar like the one zaclimon found:
http://source.android.com/source/initializing.html
The source from samsung doesnt have all the drivers, just the alsa audio driver, i guess we gonna have to find a way to get the binaries like cyanogen did, maybe get some scripts they use and try to do it ourselves:
http://wiki.cyanogenmod.com/wiki/Sa...le_CyanogenMod_(Linux)#Copy_proprietary_files
it is done through the adb, but the thing is to get those files, maybe we could ask that fellow some help for this step, since he has the experience.

The core is a ARMv7 right? because the hummingbird processor is a ARMv7. Maybe it did failed because of that? I found the gpu drivers from the opensource. Check in the kernel folder. If I can give you the gpu file if you want. Well tell me what files you are missing i'll find to give it to you. (Well I don't know how to program so I try do to my best.)
EDIT: Also its seem that to compile ICS is more difficult than the other versions. We do need ubuntu to extract the binaries right?

Maybe it is easier than the official source, they modify the source and takes out some things that cellphones dont need 'cause the source it's made for all devices, so it could be smaller and easier to compile, i'm gonna try this port and let ya' know, it will take a while since the source it's huge
Would be great if a couple of us do it, if you can @zaclimon try it, you don't need ubuntu, if you know which libaries that command has (sudo apt-get install build-essential). I have debian and i compiled the source just fine, debian has a minimal installation (no X11) but to compile source you dont need anything else! Let me know if anyone else it's triyng we could excahnge some ideas!

i'm currently in the process of pulling the system files from the original gingerbread build from the SGP...it looks like there will be some trial and error here comparing that of the nexus s build...correct me if i'm wrong, but is this where most of the proprietary libraries are located for the device?
i'm willing to engineer a generic build, described in the video tutorial and making the necessary adjustments for the ARMv7 board...
this is my first attempt at compiling Android source, so maybe we will have something or maybe i will have a good ol' brick...thanks for the great tutorial and video @zaclimon this has definitely shed some light on porting ICS for SGP

Yes they are supposed to be there. But I have download all the source code of the firmware from opensource.samsung.com
Me and sodomywar are working with the internationnal version of the SGP4. If you want to join you're welcome.
EDIT: No problem for the tutorials.

So this is where i'm at currently. I'm trying to compile and I got this error:
Code:
build/core/base_rules.mk:166: *** system/extras/ext4_utils: MODULE.TARGET.EXECUTABLES.setup_fs already defined by device/samsung/galaxyplayer. Stop.
Does anyone know how to remove that error?
EDIT: nvm I managed to remove this error.
Hi All,
First, please refrain to post if not related to development, don't clutter this thread.
Divx118, as I promised, here is my current source status.
You'll find attached the repo diff of aosp 4.0.3 where I stand up to today. It contains mostly traces, few hacks for sgx and touchscreen.
On top of this, I'm using a device definition that I uploaded there:
https://gitorious.org/archos-ics
It's a work in progress, it doesn't have half of what's needed. The init.rc is not valid, I'll attach my current one later on.
You'll find there also the 2.6.35 kernel ported from gen9, only for a70s currently. It's not finished either, I'm having crashes in backlight and touchscreen is not recognized. It requires proprietaries from LG P970 for sgx.
Currently, I'm working with this kernel so BoardConfig.mk should be modified with ARCH_ARM_HAVE_TLS_REGISTER := false to work with 2.6.29
Last, to make the build start, you'll have to grab libaudio.so and libaudiopolicy.so from regular Archos build. Sound won't work but zygote will start.
I'll update post later on, but if I wait for something finished I'm afraid it would take forever
Update 01/07 :
As many asked and I didn't make lots of progress, here is my current build. This one is using 2.6.29 kernel. sgx, touchscreen, wifi works. You *have* to edit initramfs.cpio.gz as you probably don't have the same partition layout as I do. It's for developers only, I won't explain how to make it run.
Cheers,
LeTama
*reserved*
I can't help at all in terms of development, but I will test every single release of this you guys come up with. This is a true milestone for our little seemingly abandoned tablet. I wish you guys the best, and can't wait to see what happens
Thanks Letama sorry I missed you at irc. (still have to work these holidays )
divx118
No problem divx118, same here, work and family, busy days and no time for interesting stuff
Sorry for the messy post and the code state, I wanted to push something out at least before getting caught on something else...
I added the init.rc on first post. This one is again for my .35 kernel, you'll need few adjustments for .29 (mknodes for adb and maybe few things), and it misses probably some mkdir/chmod on /data for initial boot.
Good work now i try it
I can't develop but I will also follow and do whatever I can to help.
Sent from my PG86100 using XDA App
I can develop, but I just know a delphi, basic and a little c#, java
I've been developing games for a several years now and I know how to use ADB
But I don't know anything about kernels and roms
I'll see where I can help
Little update:
I pushed my last changes for the .35 kernel, it has working touchscreen now and feels globally faster than .29. I tried few builds of wifi module for it without success, I couldn't find proper source/firmware for now. Maybe we'll get them when Honeycomb for 70IT2 goes out.
So I went back to .29 and made wifi work, unfortunately browser doesn't. Webkit is using accelerated graphics with an OpenGL extension our driver doesn't have. Does anyone know how to disable it ?
Only the Stuck Browser don´t Work
or any like Dolphin HD
when its Any try to edit webkit false fix
USE_OPENGL_RENDERER := false
And one other thing i have test to build it ... It worked but than i havnt a single .img i have many like system.img .... How can i get only one ?

USE_OPENGL_RENDERER is for framework, not webkit right ?
Framework is OK and I'd like to keep opengl there.
ENABLE_WTF_USE_ACCELERATED_COMPOSITING seems to be the key for webkit, but it doesn't seem to build properly. Oh well, I'll check that later on.

These images are useless, they're coming from panda device configuration. You have to build your own img file, mix the Archos root with the files you'll find in out/target/product/g8/system directory.
Don't forget to replace archos init.rc with the one I attached. You need to push few stock archos firmware files on top of that, libaudio.so, libaudiopolicy.so and sgx files if they were not pulled from the device when you did the build.
egl.cfg needs to be replaced too.

I pulled the kernel from your repo and compared it with latest Archos gen9 2.6.35, to get an idea of the changes you made to get it work for A70s.
Seems that you used an early release from the archos git tree.
So looking at the diff generated against latest published sources from Archos,
i realized that some of latest patches are missing.
Maybe these udates would bring us into a better situation in general.
If you got some patches of the work you made for A70s please let me know...
I'm little old fashioned and like to fiddle around with diffs and patch files
You also spoke about wifi now working with ICS in another thread...
Was this related to 2.6.29 or 2.6.35 kernel ?
Refering to the config for gen8 on 2.6.35, it seems that the you used the internal kernel wifi driver, is this correct?
So the external ti module is not working for 2.6.35... also correct?
I guess i'll try another kernel build for A101it this weekend.
Thanks a lot for your work!!!

I'm a bit better already, I made the touchscreen work. I didn't pay much attention to the change of backlight as I "workarounded" the problem by removing archos dll that controls power. I reached my initial goal, boot ICS and see if sgx drivers are better.
I believe it is, it felt quicker all around, but it didn't solve my crashes that I now believe are not really sgx related. I always see the driver as PC,LR in control panel app, but there are multiple threads and crash is probably elsewhere.
So globally kernel is nice, misses apparently only hdmi and wifi. Wifi may be difficult, we'll see. As I never compiled tiwlan, I'm back on gen9 to understand the process first.

Wifi is not working yet, need to first get a grasp on TI way, I always worked on broadcom. TI way is a bit weird for me, I have troubles understanding what version should I get in their tree. Well, we'll see. I need first to make it work for gen9...
I managed to build apparently good tiwlan.ko but while I was trying it I destroyed my gen9 config for other reason, ending up in needing a full format . And I'm good for another as I did update my firmware and forgot to put back my patched recovery, it resized my system partition to a too small size. Grrr. I think I'll work on an initrd to resize partition finally, at least it would have a benefit for the community .
I guess i'll try another kernel build for A101it this weekend.

Finally, after updating the git to .61, most changes needed were in a70 board file and back to almost the same file as A10it. So you could have good surprise there. The only delicate part is the sgx driver that I grabbed from p970, but you don't need that at first. Let me know if you get somewhere!
Cheers,
LeTama
As many asked, I added my current build. See first post for it and few details.
Hey letama,
thanks a lot for publishing your build.
It is little irritating, if useful information a is placed in seperate threads...

As this source code is not part of your repo i'd like to concentrate on implementing A101it support for 2.6.35.
It seems there'd been some additions in audio framework in one of the last patches provided by archos
Maybe these patches could be integrated in your ICS 2.6.35 kernel branch as well. Still need to fiddle around with the original sources and git, to get more information about the state of this project in general.
I'm sorry if i mix things up myself, but in fact i'd like to find some "central theme" for ICS development on Gen8.
Should we stick with the 2.6.29 kernel first?
If so it would be very nice to get some information about your patches/canges you made in 2.6.29.

Yes, untouched from Archos 2.6.29. Nothing changed on .29 kernel, just grabbed the right wpa_supplicant and fixed some permissions/directories issues. I didn't touch anything on the .29 kernel, only added the touchscreen patch that you also have on .35.

Well, raw ICS build doesn't bring audio support, we have to write or grab proper dll to supports it. I believe both kernels are probably equally good. It may be also codec issue as they're probably not working with what I did, I don't know yet.

Currently I'm not decided, I try to play with both as we may get updated drivers from Archos with the new it2 honeycomb, and they'll integrate easily with .35. However wifi is an issue with .35, not sure proper firmware+source code are available.

O.K. i see.
BTW how does the wifi firmware get loaded on the Gen9 devices?
I realized some wireless framework for the Ti chipset in the 2.6.35 kernel and i wonder if this could be used for gen8 as well.
Anyway, i'll try to find some matching Ti sources for wifi.

Time will bring it to us i guess, there are only a few OMAP3 devices running on ICS right now.

Concerning sound issue... maybe this is worth a try...

EDIT2:
For sound related libs...
http://code.google.com/p/cm-milestone2/downloads/list
I know the codec used on the milestones is different, but AFAIK the higher level libs use the DSP inside OMAP and might fit.
Milestone 2 uses OMAP3630 as well, have to check the kernel versions though.

It's similar to gen8, wlan_loader then specific wpa_supplicant. There is a good chance that Gingerbread driver works, it should against a .35 kernel too. I'll try today if work let me a bit of free time.

Situation is not clear yet. They are selling a70it2 already, but with froyo. It's not 100% confirmed that these devices are the same than the ones that will be honeycomb, but I'd bet they are.
Hi letama,
thanks for your reply.
Just in short...
I really recommend to look at the latest Gen9 kernel sources.
After stepping through the "huge" diff between these sources and your git kernel tree, i'm pretty sure that most things got included within this release.
Seems that they worked hard to integrate the OMAP3 as well.
Maybe this is because they plan to release the A70S V2 soon.
So what i did is only this...
- copy the board-archos-a70s.c (the original was still lacking quite everything)
- copy the hid-hanvon.c (ICS tweaks for touch)
AFAIK Archos did also a lot of changes in the SGX driver code.
I think it would just require some tiny tweaks to make it work with P970 libs.
Maybe there're only a few defines missing in the SGX part to get it working, but i guess that's really it.
EDIT:
Some header files are still missing in latest source as well.
So i've added them too...
- mnemedefs.h
- sgx531defs.h
- sgx535defs.h
- sgx543_v1.164defs.h
- sgx543defs.h
I'll try your archos_gen8_defconfig to compile with these latest sources.
If it does fine maybe would worth a try on your A70S.
So in fact i believe we will get a useful 2.6.35 kernel for the Gen8 soon.
The kernel already seems to be in a good shape...
Maybe we just have to sit and drink a few beers
Please tell me what you think, if you'll find soem time!
Best regards,
scholbert

Bluecat, thanks for this! I wonder if you know what differences exist between the P605 and the P607T. Also, did you use the EUR_LL source from Samsung's opensource portal? Its strange that they already have the source out for the P605, but nothing yet for the P607T which received the update first. Makes me think maybe the code base is the same and its only the bloatware bundled by the carrier that differs?
I am also curious to just learn and get my hands dirty with this. Can you share the Makefile for this kernel, or just point towards the guide you used (assuming you used one) to compile this?

Sorry,but i dont know differences between the P605 and P607T.
Yes,sources SM-P605_EUR_LL_Opensource.zip and version OI5.
If you want check have code 607 and 605 differences or not you should check checksum both original zImage(linux kernel). Extract them from both boot.img and compare.
Version 2 use standart selinux permissive way used by mostly kernel developers,it's have many changes in code now and it's will be very long to explain how to change to permissive,just use my sources available now in first post and compare them with original sources.
If you talk about how to compile kernel...was use many guides and other forums...hard part was only create .config file

Will try to extract the zImage from the P607T boot.img. I do not have the P605 though, do you know if the stock boot.img is downloadable anywhere?
Thanks for uploading the source. I just finished downloading the original source from the opensource site, will compare the two and try to understand.
I do know how to complile a linux kernel, I meant can you share the .config file (not the makefile, as I wrongly stated earlier), so I can see what has changed across the entire kernel. Rather than just change one line directly in the config file to disable SELinux, I wanted to use make menuconfig and go through the whole process, just to learn more about android kernels. But since I do not know much about the hardware and driver requirements, wanted to see a stock .config as well as your changed .config to understand.

Brilliant! Thanks for sharing ... As and when I learn anything relevant to the issue of P605 vs. P607T, will update here.
Why does the wifi password get forgotten on every boot?
Any fix for that matter?

Based on the first 5.1.1 sources, version OI5
Before installing the kernel required go to build.prop,find ro.securestorage.support and set the value to false. System may forget your WiFi passwords after flash custom kernel.
SecurityLogAgent has to be removed or frozen.
Flash kernel in odin.

Maybe you missed the update to the original post, the fix is as above, set securestorage to false. Since you have already flashed, you can still go to build.prop, make this change, reboot, and you should be fine.

I tried this. With ro.securestorage.support false. Still no WiFi passwords saved after reboot.
Other than that, this works great!
Xposed (for Samsung by wanam) works great!
valexi, the only thing Ive seen suggested in your case is to reflash the firmware. I do not know of any other solutions for this, because pretty much everybody with this problem seems to have solved it when they changed the securestorage thing.
BlueCat, I went ahead and compared checksums for the stock p607t and p605 kernels, they do NOT match. I also extracted the kernels themselves and the zimage files are of different sizes. I then compared the default config files of the P605_LL_EUR source with the only available source for the P607T, which is KK ... They are considerably different. I am of course going with the assumption that the core config for the kernel between KK and LL should not be TOO different, but of course, this is NOT a reliable test. Lastly, I should also say, the P607T source contained an insane number of config files in the Arch/Arm/configs folder, while the P605 source only had three files! I only compared the three that were common ... It seemed like the 607T has the config files for every possible version of the device, while the 605 one had very specific configs for that device only ... This I am speculating based on the fact that the 607T folder even had a msm8894_sec_l03ltmo_defconfig file in addition to the msm8894_sec_l03leur_defconfig file in the 605.
Will do more comparisons over the next few days, but it does seem like there are more changes under the hood between the 605 and the 607T than one would expect. I really wish samsung would release the source for the 607t, but if you check that page, there is just one single KK code there and nothing else, so it does not seem likely anytime soon

Ok,I found a solution.
You need to remove SecurityLogAgent

Re,
Ok remove SecurityLogAgent and folder Container it is ok...
But delete all other knox and Klm gives a problem with the playstor. (Certain protections cannot be erased)
Hey guys,
Great news around, especially with roms like Alan-B's. Thanks for sharing :good:.
Running 4.4, planning to update 5.x as soon as I'm sure I can run Linux Deploy (meaning the need of permissive kernel), though I can't find any intel about VTS (Virtual Terminal Support) enabled kernel. I've been looking for months a way to run framebuffered distros and looks like this is the solution.
I could try to make it myself but I have no experience in kernels, would someone mind give me a hand to get to this goal? At least give me a hint to "quickly" develop and try one, to see if it works and how well...
Don't even know if I'm looking the right way anymore, so thanks by advance for any help and again for the sharing :highfive:.

But when I reflash the firmware how can I set securestorage BEFORE installing permissive kernel as I don't have root to change build.prop?

You can't. Reflash, root, edit build.prop, reboot, set wifi password once again, reboot, it SHOULD be fine. If its not after this sequence, Im not sure what else may work. Every case of this particular problem that I've seen was resolved with this solution.
Luckily I didn't reflash yet. I checked again build.prop and securestorage was true. For some reason it didn't stick first time.
I edited it again and now WiFi works as intended. So I can say that this solution works. Great kernel.

Hello guys. Found this guide for kernel reverse-engineering via IDA pro. I have done several steps, but can`t separate the image itself from the extractor in the zImage file. Should i even continue, or the idea is useless? Is it`s useful, you can download and try to unpack the zimage by yourself, and i also have the symbols for a script.

I saw your post about this in another thread, and I did not want to discourage you, so I kept quiet. But, since you now ask directly, I will advise you to not waste your time. Even with full source code, kernel hacking is not for the faint-hearted, and is far from a trivial exercise. With no source code (or with incomplete source code), you might as well want to try getting hedgehogs to fly to Mars ...
Hi there! First, I'm no dev (got some experience about building Roms/Kernel from source) so sorry if I ask noobish things .
I got the same problem with the mi4s zimage (want to reverse engineer because official kernel sources are incomplete..) couldn't I just extract everything out of boot partition and create the source-code out of that? or what's the Problem by doing this? If the extracted source code (for whatever reason) is incomplete, wouldn't it be possible to get the missing things from official source released by xiaomi?
Thanks in advance

You want to extract compilable linux kernel source code from a compiled kernel? Sorry to disappoint you - but human beings will learn to climb a rope from Europe to the moon before you could achieve it. You might be able to disassemble the kernel, but you would not get anything near something compilable.
Hint: if it could readily be done, do you not think someone in these and other forums would have done it already?

There are lots of people who already did this! (see xiaomi forums redmi 3s, mi pad, Samsung galaxy s3, i9000/9001 etc. etc.). And those kernel are indeed working (even better than the ones from source) (yes, I tried it).
U ask why no one already did this? maybe because Mi4s community is very small (not even our own section..) and its quite a new device.
So why is it possible with other phones but not with mi4s?
Ty for help and explanation
Btw, can u explain it technically? not like "humans will learn to breathe in space before"....

If you mean that somebody patched a binary kernel, yes, that can be done, and I have done it myself. If you mean that somebody disassembled a binary kernel into compilable source code, I very much doubt that. If you claim that others have done it, why not post a link to the source code that they extracted, so that we too can try our hands at compiling it?

I am totally unconvinced about the claim that "it is possible with other phones". Please show the evidence.

A simple example - http://blog.packagecloud.io/eng/201...-and-disassmble-a-linux-kernel-image-vmlinuz/
Scroll to the bottom of the page and see what you will get for your efforts. Try compiling that. Better still, try editing it to add missing things or fix/remove broken things, and then compiling it. Finally, you are talking about 15 million lines of source code. Good luck.
for example here: http://en.miui.com/thread-125557-1-1.html
http://forum.xda-developers.com/android/software-hacking/how-to-reverse-engineer-kernel-t3137384
Maybe we're talking about different matters, I just want to implement UV and OC in the original xiaomi kernel to use it with smiui... As you seem to know a lot about linux kernels, how can this be done?

These are the bases of your claim that it can be done? I cannot see anywhere in those two threads where anybody was able to do anything useful with what was being proposed.

I know how to compile linux kernels when the full source code exists. I also know how to patch such sources to edit/add/remove specific things. I also know how to patch an uncompressed binary kernel if I know exactly which offset(s) to patch and which values to substitute for what is already there. I have done this for 32-bit RK3188 android kernels in my old tablets (search the ARCTABLET forums and you might see some of my historic work on overclocking RK3188 binary kernels). This was easier for RK kernels than for MTK, and much can go wrong. If all is that is needed for what you want to do is to change specific values at specific offsets, then all you need is a hex editor and the necessary information about offsets/values. If you are trying to add a new feature, then you need the full source code from the vendor.
Get yourself a backup phone before trying anything of the sort. Like I said before, I wish you good luck!
Thank you for that information. Wouldn't it be possible to edit the things in zimage (unpacked) and then just re-pack it and use it? There shouldn't be anything missing if I'm able to find the correct offset for the lzo compressor...

It is a binary file, which of course you can edit with a hex editor. But what exactly are you proposing to edit in it?
Isn't it an image containing files from Kernel? Otherwise they wouldn't talk about extracting it... Yes, I need to edit it with a hex-editor to remove the lzo header (zimage is a self extracting archive, but i want to extract it with normal zip extractor) but cant find where the header starts.

Your questions show a misunderstanding of what a kernel is. The best I can do is to refer you to Android kernel development information - see e.g.,
http://www.99droid.com/android-kernel-development-tutorial-let-the-development-begin/
http://source.android.com/source/index.html
http://source.android.com/source/building-kernels.html
At this point, I bow out of this discussion.
