Well, as an introduction to topic, you could read the following entry:
http://forum.xda-developers.com/showthread.php?t=1296186
So far, when using "-static" directive for compiler, the applications could be compiled without doing of these steps, so why do I try this? Well, a statically linked executable is embedding all the required libraries to itself, so it's generally too huge. Also, if you compile all the applications statically, you probably link the same library (like C library, for instance) twice or more for every application you compile. This is definitely unnecessary.
It's why, for a few days now, I'm trying to compile the whole GlibC suite for Android (ARM devices, to be precise). The motive behind it is simple: since all Linux applications rely on full-fledged C library (rather than trimmed version like Bionic), if I compile it for this device, I can run every application; given that its compiled for the device.
Since it's Linux kernel underneath, we don't have to worry about changing whole system from Android to native Linux (hopefully )
So far what I did was following (I'm going to write the steps more systematically once I've time, so don't worry if those steps are too vague for you ):
1- Make a toolchain for ARMv7 architecture (which Desire CPU rely on). You can use crosstool-ng etc. or (if you're masochistic enough ) try to make your own.
2- Compile GlibC with this new toolchain of yours, store the compiled libraries in a folder where you can easily access (I keep mine at Desktop/glibc-arm for instance)
3- Edit Ramdisk of the Kernel. To do this, first you must extract the boot.img; then extract the ramdisk, edit init.rc to accordingly, so the libraries can be searched in a folder other than /system/lib (say, /data/lib). You can tweak PATH env-variable while you're at it as well . This is necessary because /system partition isn't big enough to carry all GlibC lib in it, so we can copy the library to some other folder (like /data/lib) and then make the system search for libraries there as well. The point is, since I'm using Data2ext; my data is large enough for this. I'd recommend the same to you if you're willing to go on this road.
After the editing of init.rc, reconstruct ramdisk; make a boot.img with it and flash it to the device.
4- Copy the libraries to the folder of you picked.
5- Compile some test apps (like Hello world etc ) with your cross compiler and place them to your device as well.
6- Test if they're running.
What I've found so far, the cross compiled executable (like simple Hello world), when dynamically linked, gives "no such file or directory" error when tried to be run at the device (WTF, right ). However, when when I do run it with the cross-compiled ld-linux.so (the linker of C library) it runs perfectly. So what I should do to overcome this is, somehow inform the system that this ld-linux.so binary should be used.
I'll keep you updated as I try new things
Till next time, happy Android'ing
ADDENDUM 1:
EUREKA! Found the solution! It's as simple as symbolically linking the library folder of your GlibC as /lib to root file system. You can edit ramdisk accordingly to do this process automatically.
Another thing I'm going to try is finding a way to change the path of the dynamic-linker option of my cross compiler accordingly. Apparently, the cause of the problem was the compiler, telling the application to look for the dynamical linker at /lib/ld-linux.so.3; while it was at /data/lib (in my case). I can put ld-linux.so.3 to /system/lib and change compiler accordingly; but I don't know which way would be the best for flexibility: symbolic linking of /lib to library dir; or putting dynamic linker to /system/lib (the dynamic linker can look for libraries at the "custom" libdir already, since $LD_LIBRARY_PATH is already showing it).
Will try some tweaks now. If I can make it all work, I'll see if I can make a flashable zip or something (also will write whole process step by step
-------------------------------------
ADDENDUM 2!!
Well, I kept you waiting a lot, but wow, was this process head spinning. This was the first time I actually wrote a recovery script; first time I had to use AWK, SED or regex; and first time I wrote such a long scripts Well, whatever, we're done for now..
There are two zip files attached to the end of this thread: One is an installer and other is uninstaller. Just flash the recovery zip and reboot the phone. Your native C or C++ applications should run flawlessly (only added support for this two language for now) if all other dependencies are also met
Happy Android'ing guys; and well, I'd appreciate if you'd buy me a beer for that (or just click thanks, or just say thanks.. If you did all of those, you're my hero )
Here is the hero of the post :
Glibc for Android v0.9.5
Uninstaller for GlibC
NOTE: Uninstallers erase only files, not directories. Ergo, you might need to erase them yourself (had to do it for not to erase your own binaries and such).
HERE'S HOW YOU'RE GOING TO MAKE TOOLCHAIN YOURSELF (making a toolchain):
http://forum.xda-developers.com/showpost.php?p=18356849&postcount=5

Thank you very much for donations of:
Mr. Brochard and Mr. Huemer
I really appreciate it.
Eureka! Found an overcome!
Well, forgot to say this: if you want the compiled applications to be installed to some place if possible, create a "defaultinstall" file under sd-card root and write "EXT" (for sd-card) or "MTD" (for internal MTD storage) to the file (note that all uppercase).
Install manager first checks this file and if not found, uses default setting found in package (which I wrote /sd-ext generally for not-so-essential stuff ). You can use this functionality to override this setting.
Note that, some libraries and stuff cannot be installed to a different location - package manager handles this and acts accordingly; so don't worry about it
PS: The stuff I keep calling Package Manager is actually just bunch of scripts, so it's not like I wrote a whole suit
Sounds Interesting
Some compiled applications!
Well, if we're not going to use it, then why did we compiled it, right?
NOTE: The following packages don't have any specific order of installation: you can install them at any order you wish. The only exception is APT - it should be installed after DPKG, or otherwise your system will think you didn't install it
For those who hates command-line interfaces: DesirAPT (the APT front-end for Android) is here DesirAPT v1.0.0
For those who would like to run Enlightenment WM in Desire - this is the mediator application for Android: LinuxInAndroid APK
Note that it requires APT and it's dependencies, along with super user privilages.

Where the hell is the other packages?
Since we know have an APT repository for our distributions, in order to follow all the packages from one source, they won't be published in zip form anymore. In order to obtain them, or update them if you have older versions, you can use apt :
Code:
apt-get install <packagename>
The packages distributed can be list with the following command:
Code:
apt-cache dumpavail | grep Package:
OR, you can use DesirAPT to do these works.
See you around!
NOTE
Before you start anything, don't forget to install build-essentials package. Under ubuntu, the command necessary for it is: sudo apt-get install build-essential - I don't know about other distros..
-------------------------
Well, as promised, now we should write the steps; right?... Now, before we begin, I should really warn that the process is really head spinning if you're to do all by yourself; so take heed to the warnings I give you (I learned the hard way)
Well, first thing is first, we need a Cross Compiler Toolchain, properly built that allows us to build applications, libraries etc. There is one toolchain that's already given to you with Android Native Development Kit (called NDK) but that one is quite restricted because it's built with support for Bionic (trimmed C library that is presented in Android), not Glibc or uGlibC. If you want to develop more native-like applications (especially linux programs) you need GlibC or uGlibC. You can try to build these libraries with that toolchain too, but don't do that, because it's going to fail as well. The reason is that some sort of Chicken-Egg problem is eminent in GlibC-GCC compilation
Let's put the steps to be followed first to build a nice toolchain. I assume you're using Linux - because the tools are developed for this platform only. If you're going to use them in Windows, you need Cygwin or such tools but I can't supply help about that, for since I didn't use them before at all. Google is your friend about this
(Note, the packages I wrote at this list are available at GNU's website www.gnu.org freely, open source)
1- We're going to build "binutils" first. This package includes some important stuff like assembler, linker, archiver (for libraries) etc..
2- We're going to build GCC's prerequisites. These are GMP, MPRF and MPC packages.
3- We're going to build a "bootstap" gcc (God, I hate that name. I like to call it "naked gcc" more ). This GCC just converts source codes to pure assemblies: thus cannot generate linkages or such. We're going to use it to build "actual" tools we're going to use.
4- We're going to extract Kernel source/headers - use Desire Kernel's here. There is some copying, and such to be done tho.
5- We're going to make GlibC headers installed, which will allow us to build more "complex" gcc, which can link applications with those libraries when the library binaries are given (so such thing is there yet, but we fool it )
6- We're going to build a very limited GlibC which will give us support for building more "complex" gcc.
7- We're going to build GCC again. This is called "Pass 1 GCC" or "GCC Stage 1". This GCC can link applications to libraries, with the information in Kernel headers and library headers (it's why we give it the headers, so it can create applications suitable with the Kernel architecture).
8- We're to build actual GlibC now. This glibC will be used for our compiled applications, statically or dynamically. You can, at the end of this step, copy the files to your devices and they would work, but picking files here is harder, so I'd recommend you to leave this alone for now
9- We're going to build "Pass 2 GCC" or "GCC Step 2" This is a full fledged GCC that can do anything we want
Complex isn't it? This is precisely why I recommend you to use Crostool-NG. The other tools (like Buildtools or Crosstool) (sadly) don't create GlibC based toolchains, or use old versions of them, so using this one is recommended. This package automatically will download, setup and link your all toolchain without you worrying about something (believe me, this is what you need. I gave 8 days without this to create a working GCC and Crosstool-NG made another one to me in 50 minutes. )
Well, however, Crosstool-NG won't create "nice" applications (they'll run allright, but they won't be optimized) without some settings done, so, let's go there. First, we need to install Crosstool-NG itself. To do that; go to http://crosstool-ng.org/ website, download and extract it to some place. Even though the steps are written in Crosstool website, you don't need all commands there (like setting PATH is unnecessary). The commands you should use is, after CD'ing to the Crosstool dir;
./configure --prefix="</some/place>"
make
make install
cd "</some/place/bin>"
./ct-ng menuconfig
I used prefix as /home/ahmet/crosstool for instance. Note that this is not going to be where your toolchain is, this is where your "toolchain creator" is .
---- NECESSARY KERNEL HEADER CHANGES ----
OK now, before we start compiling; we need to make some folder moving, copying etc. in Kernel directory. This is needed, because tree structure changed a tad in 2.6 kernels and unless you compiled this kernel before, some directories won't be in their correct place for our cross compiler. Switch to the directory which you extracted the kernel image. Now, from now on, I'm going to assume you're an Qualcomm/MSM board (like Desire, Nexus One etc.) user; but if you're not, change my descriptions accordingly:
1- Go to <kernel dir>/arch/arm/include folder. Copy "asm" directory and paste it into <kernel dir>/include directory.
2- Go to <kernel dir>/arch/arm/mach-msm/include folder. Copy "mach" directory and paste it to <kernel dir>/include/asm directory. It's going to complain that there is another mach folder there and will ask if you want to merge/overwrite. Say yes to all questions.
Now our kernel headers folder is showing a Desire device. Note that if you're not a Desire user, you should use your cpu folder instead of ARM and your board manufacturer in mach-xxxxx instead of mach-msm.
Note this kernel directory, we're going to use it to configure crosstool..
--- CONFIGURING CROSSTOOL ---
After issuing the commands, the crosstool-ng will give you a configuration menu. Most of the setting here are unchanged, but the ones you should change are given below.
1- Paths and misc options
a) Try features marked as EXPERIMENTAL (this is needed to build a toolchain with the latest GlibC support) -> Enabled
b) Local Tarballs directory -> The folder address that you want downloaded stuff to be kept. You might use them again (like for compiling GlibC again for device, you will use them
c) Save New Tarballs -> Enabled ( so that new downloaded files aren't erased )
d) Working Directory and Prefix directory -> Normally you don't have to change them, but you can if you want to install your toolchain to some other location. CT_TARGET signifies your target name (like arm-msm-linux-gnueabi - arm is cpu model, msm is vendor (can be anything), linux is showing the binaries are for linux system (you can use android, but then you'll get not GlibC but Bionic) and gnueabi shows you're going to use open-source EABI structure for your executables. The other option is ELF but EABI is more flexible (because also supports ELF).
e) Strip all toolchain executables -> do it if you don't want to debug GCC itself. this makes toolchain smaller of size, and a tad faster.
The other options can stay the way they are, or you can change them accordingly here. You can get help with ? key, and if you don't understand anything, just leave them default - there are very complex things there that you don't need to know if you're not planning to be a expert on subject
2- Target options
a) Target Architecture -> arm should be selected, cos Desire uses ARM. If you plan to make toolchain for, say, powerpc, pick that.
b) Endianness -> Should be little. ARM processors in Desire uses little endian system.
c) Architecture level -> "armv7-a" this is should be written. Desire uses ARMv7 based instructions and if you leave here empty, the applications will be built with armv5 support - they're still going to run but not use advanced v7 features.
d) Use Specific FPU -> "neon" . Desire uses NEON structure for floating point arithmetic, and if you leave here empty, the applications will not use Desire's FPU abilities (everything will be software based, which is slower)
e) Default instruction set mode -> arm . You can use thumb here for allegedly faster code but not every build system supports it. Leave it ARM.
f) Use EABI -> enabled. EABI is necessary for most flexible desing of binaries.
The other settings be as they were.
3- Toolchain options
a) Tuple's vendor string -> You can leave here empty if you don't want to; it's not necessary to use a string here. I used "msm" but you can write anything. This string here is used in toolchain name as arm-xxxxx-linux-gnueabi, so make it short, I recommend
b) Tuple's alias -> make it something short like "arm-linux" This alias string is used to make calls to your toolchain easier. Instead of writing arm-msm-linux-gnueabi-gcc everytime, you can use arm-linux-gcc to compile your applications. Can write anything here (like toolchain if you want to use toolchain-gcc to compile your applications)
The other settings can stay as they are, for since default values are the best in our case. You can tweak them only if you know Desire cpu like the back of your hand
4- Operating system
a) Target OS -> Use "linux" if you want the applications to run in Android and Linux; use "bare metal" if you're to compile low level applications which won't use linux headers. Default is linux.
b) Get Kernel headers from -> say "pre installed" because otherwise it's going to download standard Linux headers from internet. We needed some changes, so this option is compulsory to be "pre installed"
c) Path to custom headers directory/tarball -> Path to your kernel source folder - which you made changes above. WARNING: I say specifically extracted, because standart tarball won't work for us. We're going to make some changes in kernel directories, which is non-standart (Instructions were above).
d) This is a tarball -> No . We're going to use extracted folder.
e) Build shared libraries -> say "yes"; because we want dynamic linkage, not static one
f) Check kernel headers -> say "no" otherwise some unnecessary check causes compilation to stop.
5- Binary utilities
a) Binutils version - pick the latest one, 2.20.1a. If you use older versions with newer GCC/GlibC, it's not going to succeed.
Leave others as they are, they are not big deal..
6- C Compiler
a) GCC Version -> pick 4.6.1 for since it's the latest and most bug free. Just stay away from 4.5
b) Pick the languages you want support for. I've read online that Java is a tad troublesome in Android platform, for since Java in Android uses Dalvik, not Sun systems. You can try it at your second toolchain if you want Definitely pick C++ tho
c) Link libstdc++ statically -> say yes; it really saves you from big configure scripts later - apparently needed to avoid PPL problems as well
d) Compile lidmudflap/libgomp/libssp -> say no. These libraries are not the most suitable libraries for ARM platform (at least at cross-compiler level. You can compile them later, if you want, with your cross-toolchain.)
You can leave others as default
7- C library
a) C library -> gLibC (recommended). You can use other libraries which are eGlibC (embedded Glibc, like Bionic) and uGlibC (micro-glibc) too, but GlibC is the most spanning solution above those. The libraries are bigger, but they support more.
b) glibC version -> Use 2.13 (experimental) it compiles just fine, and you get a new version of GlibC. Not the newest, but that's ok
c) Threading implementation -> nptl (recommended) . You can use linuxthreads too, but nptl is more advanced ( like giving support to Thread-Local-Storage and such)
d) Force Unwind Support -> Enabled . If you don't use this option, for since we're making this toolchain from scratch, it's going to give you error during compiling that it couldn't find necessary headers (we're building them now, dumbass!)
Leave others default if you don't know what they're about
8- Companion Libraries
Well, go and pick the latest versions, even though when it says "Experimental", otherwise your GCC compilation will give you error about these libraries being old.
After setting these settings, press ESC key twice till it goes way back and ask if you want to save configuration; say yes.
--- STARTING COMPILATION ---
Now to start compilation write
./ct-ng build.
This is going to take approx. 45 minutes, so go watch some episodes of Big Bang Theory or something. Normally, there should be no errors but if there is; most probably either you made a wrong configuration, or didn't set your kernel folders well. Try again with other settings, google your problem etc..
After this process, you're going to have a cross-compiler at your use at /home/<username>/x-tool/arm-<vendor>-linux-gnueabi/bin folder. Note that Crosstool-NG automatically makes this folder read only to make you prevent screwing your toolchain You must edit your path variable to show "/home/<username>/x-tool/arm-<vendor>-linux-gnueabi/bin" folder as well for less headaches during compiling later
Whilst compiling other application, most used configure options you're going to use is "--host=arm-<vendor>-linux-gnueabi" and "--prefix=/some/folder/you/want/this/application/copied". After compilation, you can send binaries to your phone from prefix folder.
More options about GCC and Configure is available at GCC and Autoconf man pages; check them as well
Happy cross-compiling people
Woah, amazing work, congrats!

Interesting..It answers some of my unanswered queries regarding cross compiling.. Thanks...Please keep documenting your progress.
THIS POST IS ONLY FOR THE BRAVE MAN
These are packages which are compiled; but not installed and/or tested by myself. Please test them and inform me if they work (PM me if they work or not; it's better that way ).

NO PACKAGES HERE! Frankly, I did test virtually all of them. They might not work as expected maybe, but at least they don't impede functions of device
Developer Log
Now while preparing a suitable (and as flexible as it can) recovery zip; I realized that instead of editing ramdisk, I can also use init.d script to link /lib to /data/lib. This also allows some flexibility to user (i.e. move library folder around -if needed- and edit init.d script accordingly and still have a running system).
What baffles me most is PATH env-variable. Apparently, if I set it at init.d level, it's not exported quite well - apparently, there is a user mode switch between init.d script run and ramdisk loading process (because PATH variables at Ramdisk are exported to all applications, whilst init.d ones are not) and the only way to set PATH variable for all processes is editing Ramdisk (AFAIK)...
And another point: what if kernel doesn't support init.d? (Go to hell if you're reading this post with a kernel which doesn't ) Ramdisk solution is quite general (i.e. works for everyone) but it's a little harder to edit with scripts and not as flexible as init.d method. I think it's safe to assume that there is init.d support at this level
Maybe I can create two versions (init.d one and ramdisk one) of recovery zip's.. Keep in touch guys..

Well, what's the difference between init.d and ramdisk, when init.d support means running busybox runparts from ramdisk?

Well the difference is caused by Unix variable propagation.
Normally, when ramdisk is loaded and init.d scripts are starting to run (with run-parts binary) the exported variables are valid only for the scripts that run-parts do run. Since Linux only allows child processes to inherit variables from host, when runparts finishes job; defined variables within the scripts vanish.
When you add variables to Ramdisk (init.rc) directly, since variables become declared from init directly (and since init runs all the processes on boot) the variables automatically become available for all processes.
That's the difference I meant
Got it..So the variables from init.rc persist till shutdown..

Precisely. It's why the variables (even those which defined by export keyword) are vanished when the system booted up (unless defined in ramdisk)
Well, I've gotta learn RegEx one day anyways
Recovery zip is done! Now, I should test it on my device first
I'm also going to make a uninstaller script I think. It's really messy to clean this up otherwise
Android binaries and dependencies
I've examined the dependencies of all the binaries in /system/bin and /system/xbin in Android system. Too sad that the list contains some non-standart libraries (that's not that bad, sure you can find their sources).
Also, another problem is that you need to compile the binaries themselves from the source code as well (with the GlibC libraries) - which is near to the compiling the whole ROM itself - I'm not even sure if we can find source code (will check the Android source code itself when I've time)
The dependencies in my system, for instance, are as follows:
So that's a no-go for people with closed source system...
@theGanymedes, do you know if the system can mount ext4 at init.rc level (on early init) without using busybox?
Well, it can, but the kernel needs ext4 modules (or direct support). I checked the native mount source, it actually does nothing much more than simply calling kernel's ioctl or mount system call..
I think a simple tweak at ramdisk is all you need for that (and a supporting kernel, of course )
Weird thing about previous issue is, I have the source codes of most utilities, I can compile them too, but I don't have proper makefiles and I'm too lazy to write them myself - that's a lot of trial and error.
Well, apparently, we're not going to be able to switch from Bionic to Glibc completely. I think I can make them coexist tho.

Yup, my compiled kernel has direct support.
This is how mtd is mounted..
mount yaffs2 [email protected] /data nosuid nodev
And this is how I mount ext4 from init.d:
/system/xbin/busybox mount -t ext4 -o barrier=0,noatime,nodiratime,nosuid,nodev,nobh,nouser_xattr,noauto_da_alloc,commit=50 /dev/block/mmcblk0p2 /data
I need to change it to init.rc (init) language...

So, I'm not barking for the hollow tree here.. That's a relief. Seeing that this post is not that active, I was starting to think I'm working in vain..
Well, now, apparently init version of mount is quite restricted about options. The ones it supports are given in mount.c as:
Code:
"async", "atime", "bind", "dev", "diratime", "dirsync", "exec", "move", "recurse", "remount", "ro", "rw", "suid", "sync", "verbose"
I'm checking the mount.c source as we speak. I'm going to inform you if I can find something.
EDIT: BTW, also "no"+options are recognized (like noatime)
ADDENDUM:
The internal mount is exactly the same as the mount we use at busybox. So, most probably, it's the same was in init script.
Try this line
Code:
mount ext4 /dev/block/mmcblk0p2 /data noatime,nodiratime,nosuid,nodev,nobh
Notice that I erased some flags. You might also try to add them, but check if this line works first.

Hello there,
here is a new tutorial I'm sure you'll like. As usual it took me LOTS of work to get all info and make this to work, so now I share it with you and show how to run custom ROMs within Android SDK Emulator.
Please note it's mainly for XPERIA X10, but process is the same for other Android-powered devices. It will show you the process for Linux.
1. Download the latest Android SDK.
2. Open the archive, and copy the folder android-sdk-linux-x86 to a safe place. You can also rename it to an easier name. Example : I placed it in ~/Home and renamed it androidsdk.
3. Go to the SDK folder, then in the folder Tools/. Double-click on Android and choose Run.
4. Go to Available packages, and choose to install (choose at your will !)
Android SDK Tools, revision 8
Android SDK Platform-tools, revision 1
SDK Platform Android {VERSION(S) YOU WANT} (!) You need at least one Platform. For X10, you can download 1.6, 2.1. You can also add 2.2, 2.3.
Once it's done, close the window.
5. Download Xperia X10 add-on for SDK. (?) Read the PDF add-on guide, it is helpful !
Copy the folder (from the archive) XPERIA-X10_r1 inside the folder add-ons of your Android SDK folder ({androidsdk}/add-ons/).
6. Run terminal, go to your Android SDK folder, then in tools folder, and run
Code:
./android list target
.
Note the id number of the Android you want to develop (ie for me, Android 2.3 is
Code:
id: 3 or "android-9"
). (?) You might also want to note the name ("android-X") as it might be useful later.
7. Now, create AVD (a profile for emulator). Usual command (assuming you are INSIDE the /tools/ folder !) is
Code:
android create avd -n NAMEYOUWANT -t {ID}
So, for us, it will be
Code:
./android create avd -n myx10 -t 3
8. To generate the AVD, you will be prompted several info. Type these for Xperia X10 :
Create custom hardware profile : yes
SD Card support : yes
Asbstracted LCD density : 160 (correct if I'm wrong ?)
DPad support : no (?)
Accelerometer : yes
Max camera pixels (H) : 3264
Cache partition size : 66 (?)
Audio playback : yes
Trackball : no (?)
Max cam pixels (V) : 2448
Camera support : yes
Battery support : yes
Touch screen : yes
Audio record : yes
GPS : yes
Cache partition : yes
Keyboard : no
heap size : 32
RAM : 280
GSM Modem : yes
(?) I recommend you to create one profile for each Android version you want to run (so : you just have to change the ID, and create same profile). If you don't, you won't be able to run custom ROMs using other versions of Android (ie your AVD profile is 2.3 and you run a 2.1 custom ROM).
9. Done ! Take your custom ROM (downloaded, compiled... In this case, files are in {YourAndroidRepoFolder}/out/target/product/generic/. It comes with about 3 files, including a file called system.img. Copy this file into the folder (hidden) .android/myx10{In fact, the name you've chosen earlier "NAMEYOUWANT"}.avd/
10. Run terminal, go to Android SDK folder/tools/ (if you didn't close your current terminal, you're already in and run this command to run emulator WITH your custom ROM :
Code:
./emulator -avd myx10{again the "NAMEYOUWANT" you've chosen before}
Wait and enjoy !
(?) First boot is long - it's NORMAL. Just like on a real device, the OS will be cached and will work faster and faster.
AnyKernel3 -- Flashable Zip Template for Kernel Releases with Ramdisk Modifications
"AnyKernel is a template for an update.zip that can apply any kernel to any ROM, regardless of ramdisk." - Koush
The concept of AnyKernel has been around for awhile, (originally by Koushik Dutta/ClockworkMod,) which allowed a device-specific kernel zImage to be flashed over device-specific ROM and use the ramdisk that came with the ROM to reduce the chance of any issues arising from the custom kernel pairing.
The drawback to this was that some kernels require modifications to the ramdisk to enable/set up kernel features, and in the old AnyKernel format there was no way to do this. Enter AnyKernel2.
AnyKernel2 pushed the format even further by allowing kernel developers to modify the underlying ramdisk for kernel feature support easily using a number of included command methods along with properties and variables to customize the installation experience to their kernel. AnyKernel3 adds the power of topjohnwu's magiskboot for wider format support by default.
A script based on Galaxy Nexus (tuna) is included for reference. An example of ramdisk-only changes can be seen in my GN Synapse Injector repo. For an example that also modifies ROM and properly injects init.d support using busybox run-parts and sepolicy-inject see CosmicDan's CosmicTweaks project. For a multi-partition example and an example of how to handle a device which only has a ramdisk when rooted see my N5X/6P BLOD Workaround Injector. Other working AK2/3 examples for more recent devices may be found on eng.stk's blu_spark device repos under Releases.
Please see the linked posts here for instructions on enabling full AVBv1 (Pixel), AVBv1, A/B slot and/or system-as-root (SAR) or 2-stage init (2SI) device support, and further guidelines for system-as-root/2-stage init (/system/system in recovery) modifications in general.
Please also see the post here for important notes about the current state of AOSP vendor_boot v4 support and AVBv2 flag options.
Magisk root is automatically detected and retained by patching the new Image.*-dtb as Magisk would!
My development work on my many projects comes out of my free time, so if you enjoy this project or anything else I've done on xda, please consider sponsoring my ongoing work using my GitHub Sponsors profile. For a one-time donation you can hit the donate link from my profile. Thank you for your support!
Source: https://github.com/osm0sis/AnyKernel3/
Download: https://github.com/osm0sis/AnyKernel3/archive/master.zip
Instructions
1) Place final kernel build product, e.g. Image.gz-dtb or zImage to name a couple, in the zip root (any separate dt, dtb, recovery_dtbo, dtbo and/or vendor_dlkm should also go here for devices that require custom ones, each will fallback to the original if not included)
2) Place any required ramdisk files in /ramdisk (/vendor_ramdisk for simple multi-partition vendor_boot v3 support) and module files in /modules (with the full path like /modules/system/lib/modules)
3) Place any required patch files (generally partial files which go with AK3 file editing commands) in /patch (/vendor_patch for simple multi-partition vendor_boot v3 support)
4) Modify the anykernel.sh to add your kernel's name, boot partition location, permissions for any added ramdisk files, and use methods for any required ramdisk modifications (optionally, also place banner and/or version files in the root to have these displayed during flash)
5) `zip -r9 UPDATE-AnyKernel3.zip * -x .git -x .github README.md *placeholder`
The LICENSE file must remain in the final zip to comply with licenses for binary redistribution and the license of the AK3 scripts.
If supporting a recovery that forces zip signature verification (like Cyanogen Recovery) then you will need to also sign your zip using the method I describe here:
[DEV][TEMPLATE] Complete Shell Script Flashable Zip Replacement + Signing [SCRIPT]
Not required, but any tweaks you can't hardcode into the source (best practice) should be added with an additional init.tweaks.rc or bootscript.sh to minimize the necessary ramdisk changes. On newer devices Magisk allows these within /overlay.d - see examples.
It is also extremely important to note that for the broadest AK3 compatibility it is always better to modify a ramdisk file rather than replace it.
If running into trouble when flashing an AK3 zip, the suffix -debugging may be added to the zip's filename to enable creation of a debug .tgz of /tmp for later examination while booted or on desktop.
Staying Up-To-Date
Now that you've got a ready zip for your device, you might be wondering how to keep it up-to-date with the latest AnyKernel commits. AnyKernel2 and AnyKernel3 have been painstakingly developed to allow you to just drop in the latest update-binary and tools directory and have everything "just work" for beginners not overly git or script savvy, but the best practice way is as follows:
1) Fork my AnyKernel3 repo on GitHub
2) `git clone https://github.com/<yourname>/AnyKernel3`
3) `git remote add upstream https://github.com/osm0sis/AnyKernel3`
4) `git checkout -b <devicename>`
5) Set it up like your <devicename> zip (i.e. remove any folders you don't use like ramdisk or patch, delete README.md, and add your anykernel.sh and optionally your Image.*-dtb if you want it up there) then commit all those changes
6) `git push --set-upstream origin <devicename>`
7) `git checkout master` then repeat steps 4-6 for any other devices you support
Then you should be able to `git pull upstream master` from your master branch and either merge or cherry-pick the new AK3 commits into your device branches as needed.
Enjoy!
Questions, comments and feedback welcome.

Script Commands Reference
Everything to edit is self-contained in anykernel.sh. A quick-reference for the commands and properties included are as follows.
Properties / Variables
These are some values that will be read during the install process, allowing you to customize your installation, e.g. block= is a shell variable to specify the kernel/boot block partition that the dump_boot command method will copy and unpack.
Code:
kernel.string=KernelName by YourName @ xda-developers
do.devicecheck=1
do.modules=1
do.systemless=1
do.cleanup=1
do.cleanuponabort=0
device.name1=maguro
device.name2=toro
device.name3=toroplus
device.name4=tuna
supported.versions=6.0 - 7.1.2
supported.patchlevels=2019-07 -
block=/dev/block/platform/omap/omap_hsmmc.0/by-name/boot;
is_slot_device=0;
ramdisk_compression=auto;
patch_vbmeta_flag=auto;
do.devicecheck=1 specified requires at least device.name1 to be present. This should match ro.product.device, ro.build.product, ro.product.vendor.device or ro.vendor.product.device from the build.prop files for your device. There is support for as many device.name# properties as needed. You may remove any empty ones that aren't being used.
do.modules=1 will push the .ko contents of the modules directory to the same location relative to root (/) and apply correct permissions. On A/B devices this can only be done to the active slot.
do.systemless=1 (with do.modules=1) will instead push the full contents of the modules directory to create a simple "ak3-helper" Magisk module, allowing developers to effectively replace system files, including .ko files. If the current kernel is changed then the kernel helper module automatically removes itself to prevent conflicts.
do.cleanup=0 will keep the zip from removing its working directory in /tmp/anykernel (by default) - this can be useful if trying to debug in adb shell whether the patches worked correctly.
do.cleanuponabort=0 will keep the zip from removing its working directory in /tmp/anykernel (by default) in case of installation abort.
supported.versions= will match against ro.build.version.release from the current ROM's build.prop. It can be set to a list or range. As a list of one or more entries, e.g. 7.1.2 or 8.1.0, 9 it will look for exact matches, as a range, e.g. 7.1.2 - 9 it will check to make sure the current version falls within those limits. Whitespace optional, and supplied version values should be in the same number format they are in the build.prop value for that Android version.
supported.patchlevels= will match against ro.build.version.security_patch from the current ROM's build.prop. It can be set as a closed or open-ended range of dates in the format YYYY-MM, whitespace optional, e.g. 2019-04 - 2019-06, 2019-04 - or - 2019-06 where the last two examples show setting a minimum and maximum, respectively.
block=auto instead of a direct block filepath enables detection of the device boot partition for use with broad, device non-specific zips. Also accepts any partition filename (from by-name), e.g. boot, recovery, or vendor_boot.
is_slot_device=1 enables detection of the suffix for the active boot partition on slot-based devices and will add this to the end of the supplied block= path. Also accepts auto for use with broad, device non-specific zips.
ramdisk_compression=auto allows automatically repacking the ramdisk with the format detected during unpack. Changing auto to gz, lzo, lzma, xz, bz2, lz4, or lz4-l (for lz4 legacy) instead forces the repack as that format, and using cpio or none will (attempt to) force the repack as uncompressed.
patch_vbmeta_flag=auto allows automatically using the default AVBv2 vbmeta flag on repack, and use the Magisk configuration (Canary 23016+). Set to 0 forces keeping whatever is in the original AVBv2 flags, and set to 1 forces patching the flag (only necessary on few devices).
customdd="<arguments>" may be added to allow specifying additional dd parameters for devices that need to hack their kernel directly into a large partition like mmcblk0, or force use of dd for flashing.
slot_select=active|inactive may be added to allow specifying the target slot. If omitted the default remains active.
no_block_display=1 may be added to disable output of the detected final used partition+slot path for zips which choose to include their own custom output instead.

"if search string" is the string it looks for to decide whether it needs to add the tweak or not, so generally something to indicate the tweak already exists. "cmdline entry name" behaves somewhat like this as a match check for the name of the cmdline entry to be changed/added by the patch_cmdline function, followed by the full entry to replace it. "prop name" also serves as a match check in patch_prop for a property in the given prop file, but is only the prop name as the prop value is specified separately.
Similarly, "line match string" and "line replace string" are the search strings that locate where the modification needs to be made for those commands, "begin search string" and "end search string" are both required to select the first and last lines of the script block to be replaced for replace_section, and "mount match name" and "fs match type" are both required to narrow the patch_fstab command down to the correct entry.
"scope" may be specified as "global" to force all instances of the string/line targeted by replace_string, replace_line or remove_line to be replaced/removed accordingly. Omitted or set to anything else and it will perform the default first-match action.
"before|after" requires you simply specify "before" or "after" for the placement of the inserted line, in relation to "line match string".
"block|mount|fstype|options|flags" requires you specify which part (listed in order) of the fstab entry you want to check and alter.
dump_boot and write_boot are the default method of unpacking/repacking, but for more granular control, or omitting ramdisk changes entirely ("OG AK" mode), these can be separated into split_boot; unpack_ramdisk and repack_ramdisk; flash_boot respectively. flash_generic can be used to flash an image to the corresponding partition. It is automatically included for dtbo and vendor_dlkm in write_boot but can be called separately if using "OG AK" mode or creating a simple partition flashing only zip.
Multi-partition zips can be created by removing the ramdisk and patch folders from the zip and including instead "-files" folders named for the partition (without slot suffix), e.g. boot-files + recovery-files, or kernel-files + ramdisk-files (on some Treble devices). These then contain Image.gz, and ramdisk, patch, etc. subfolders for each partition. To setup for the next partition, simply set block= (without slot suffix) and ramdisk_compression= for the new target partition and use the reset_ak command.
Similarly, multi-slot zips can be created with the normal zip layout for the active (current) slot, then resetting for the inactive slot by setting block= to the partition (without slot suffix) again, slot_select=inactive and ramdisk_compression= to the desired options for the target slot and using the reset_ak keep command, which will retain the patch and any added ramdisk files for the next slot.
backup_file may be used for testing to ensure ramdisk changes are made correctly, transparency for the end-user, or in a ramdisk-only "mod" zip. In the latter case restore_file could also be used to create a "restore" zip to undo the changes, but should be used with caution since the underlying patched files could be changed with ROM/kernel updates.
You may also use ui_print "<text>" to write messages back to the recovery during the modification process, abort "<text>" to abort with optional message, and file_getprop "<file>" "<property>" and contains "<string>" "<substring>" to simplify string testing logic you might want in your script.
Binary Inclusion
The AK3 repo includes current ARM builds of magiskboot, magiskpolicy, lptools_static and busybox by default to keep the basic package small. Builds for other architectures and optional binaries (see below) are available from the latest Magisk zip, or my latest AIK-mobile and Flashlt packages, respectively, here:

https://forum.xda-developers.com/t/...-and-ends-multiple-devices-platforms.2239421/ (Odds and Ends thread)
Optional supported binaries which may be placed in /tools to enable built-in expanded functionality are as follows:
mkbootfs - for broken recoveries, or, booted flash support for a script/app via bind mount to /tmp (deprecated/use with caution)
flash_erase, nanddump, nandwrite - MTD block device support for devices where the dd command is not sufficient
dumpimage, mkimage - DENX U-Boot uImage format support

You get 2 thank button presses fro me lol
Awesome work man as always
Good thing that this amazing work has it's own thread. Congrats buddy.

Thanks guys!
I figured it would be nice to get it out there and also have it as a "Help Desk" thread for kernel devs who have questions about implementation, etc. too. Some devices might require switching it from dd to MTD-Utils, so I can help with that. So on and so forth.
Once we get a few devs who know how to use it, it should be pretty easy to help others. I'm looking at you Smitty. No pressure.
I finished my thanks ... but as always a great job.

So wait im confused. ?.. so 1) those that mean I can flash ak kerenl 4.2 with ur any kernel to my 4.4 .
2) those it have to be same kerenl for same phone manufacturer. Meaning can I be stupid enought to flash a nexus 4 kernel in my gnexus?
I understand any kernel cause I have been using smitty so thanks

Haha I wrote "device-specific" in the OP to try and avoid this very confusion.
Since I answered this same question earlier tonight in my Odds and Ends thread I'll just paste it here:

No. That's crazy talk. :laugh:
The concept of AnyKernel has been around for awhile, (originally by Koushik Dutta/ClockworkMod,) which allows device-specific kernels to be flashed over device-specific ROMs and use the ramdisk that came with the ROM to reduce the chance of any issues arising from the custom kernel pairing.
The drawback to this is that some kernels require modifications to the ramdisk to enable/set up kernel features, but in the old AnyKernel format there was no way to do this. Until now.
AnyKernel 2.0 makes it easy for kernel devs to use a number of simple command methods to automate the process of adding tweaks into a ROM's underlying ramdisk during the flashing process. :good:

Hopefully that helps. Basically exactly what's in the OP since that's where I edited it in from.
The only way I can explain it any further is with the very basics: that kernel boot.img files contain a zImage and a ramdisk. "AnyKernel Classic" just slaps the custom kernel zImage on top of the ROM's untouched default kernel boot.img ramdisk. AnyKernel 2.0 allows kernel devs to also modify the ramdisk to add anything required for kernel features in addition to the usual repacking it with the custom zImage and flashing it.
Great thread!! Best of lucky bro!!!

AnyKernel will work on my phone now ? Thanks for enhancing awesome @osm0sis but DrRamdisk to the rest of you guys ?
wow,thats very cool,great work.
Github updated with my own forked native compiles of mkbootimg+unpackbootimg.
This should expand AnyKernel 2.0 device support a lot by using all the available offsets in mkbootimg, as exported by my drastically updated unpackbootimg. :good:

Hi osm0sis,
Have You update anykernel 2.0 to work with cyanogen11 roms ? Thanks for Your hard work !
Should already?
It uses the ROM kernel ramdisk like AnyKernel always has. Your custom kernel dev just needs to use it. Spread the word. :good:

Recently I had used Your method on Cyano11 but boot stopped on "Google".. new Cyano11 (that required ramdisk changes) had just come out and maybe anykernel 2.0 was not ready yet (I had just discovered your brillant work on It ! : Dita incrociate.
I'll try again ... if I have trouble going to ask you for help ...
I am already spreading the word : Cool:
Thanks man : Good:
What custom kernel were you trying to adapt to AnyKernel so you could flash it on CM?

Two kernels... My custom kernel (from cyanogenmod sources) and recently Fancy kernel (dirty-fancy)... now I want to try Fancy Kernel .. I need of a hibryd ramdisk for best final results and Your project is perfect for It !!! You're a genius !!!
Please, Can You link me Your dirty-V kernel re-pack by Anykernel 2.0 ? So I can follow It as an example. Thanks a lot...
So if I understand you, you're trying to make an AnyKernel 2.0 of Fancy Kernel so that you can flash it on any ROM for your device?
Should be doable. The DirtyV AnyKernel 2.0 is the example posted to the GitHub repo in the OP. Just follow the instructions to make your own anykernel script so that it will add the /sbin/ scripts and other ramdisk modifications (init.d, etc.) that @boype uses, instead of the DirtyV ones.
Good luck!

osm0sis ? If I want include init.rc original file by "real" ramdisk can I copy It as is into patch folder ?
It would go against the idea of AnyKernel to include the file like that. Remember, everything automatically comes from the original ramdisk, I just give you the ability to alter those files to add tweaks. :good:
The purpose of this thread is to provide a guide for users who have Proxyme preloaded in their device's firmware and want to find out how to use it effectively. Ideally, this will be a place to share experiences and ideas to further improve the tool and provide solutions to problems that people may have.
Introduction
Proxyme ( proc-zahym ) represents a system access solution comprised of the following components:
System service - provides access to privileged system environment
SSH daemon - provides secure shell (ssh) and file (scp) access (based on dropbear)
proxyme.apk - user interface module
This solution is offered as a preloaded option in firmware images and consequently cannot (should not) be installed as a regular app, either from the Play Store or being side loaded. The reason for pre-loading stems from the requirements of the system service component to be able to integrate at system level and not be bound by operating restrictions within the Android application and framework platform environment (Zygote and Dalvik sandbox). The Play Store has been enlisted as the primary and preferred source in providing updates to the user interface component; the actual app you will be interacting with.
Proxyme offers the following functionality through its user interface:
Installation/de-installation of the su binary to provide/remove root access
(useful only for other applications which require root level access)
The persistent behaviour of the su binary can be controlled by a one-shot switch
Register/de-register tag-along scripts for su enable and disable actions
(more details on this below)
Control availability and location of busybox toolbox
Start/Stop SSH daemon
Configure listening port for the SSH daemon
Configure user accounts for the SSH daemon
Submit and execute a shell script
SU Binary
The option to enable or disable the su binary switch (on/off) in the user interface is the equivalent of rooting and unrooting the device. When enabled, you are providing root access to apps which require it to perform correctly. Currently, Proxyme does not have built-in support for monitoring and 'policing' the actual access to root.
Auto Root @ Boot
This switch in the Proxyme app allows you to indicate whether the su binary should be installed or removed during a reboot or startup of the device. Setting it to the 'on' position will make the su binary persistent throughout reboot cycles and leave your phone permanently 'rooted'.
Registering Tag-along Scripts
Whenever you enable or disable the su binary with the on/off switch in the user interface, there exists an option to execute a user script just prior to and one unique to each action. This is possible by pre-registering a script for one of or both enable/disable actions. A script can virtually perform anything and is always executed within root context. Note that you must be very cautious about the scripts you are registering and be certain about their intentions, because a rogue script could cause irreparable damage to you device.
Each script has the option to override, and thus block, the intended action (enable or disable) by setting a system property named proxyme.override to anything but blank.
One purpose of having tag-along scripts would be to 'freeze' and 'unfreeze' specific root-shy apps, which do not 'like' rooted systems. This is one area where we can share the experience of pre-coded scripts for certain target apps and I do hope it will be put to good use.
To submit a script file, tap on one of the SU Enable Script or SU Disable Script text elements to start browsing for a file.
Busybox
Busybox is just that, busybox. Options are available to determine one of two hard-configured locations where it can be installed and to enable or disable it.
More to follow later...
SSH Daemon
The SSH daemon is based on dropbear. It has been modified to support logon accounts in Android, which are configured with the following parameters:
username
password
home directory
which shell to use
user ID
group ID
For whatever reasons, you can restrict access by specifying non-root user and group (0:0) IDs. The IDs you can choose from are derived from a system list which was used and known within Android at the moment of booting the device. If you have installed new apps in the meantime and would like to use their newly assigned IDs, then please reboot the phone to update this list.
Executing Shell Scripts
The ability to submit and execute a shell script from the user interface can be considered a convenient and quick way to get some tasks done. Take note however that your scripts are run in a privileged environment under the root account and that there are risks involved. A rogue or insufficiently tested script can cause major problems if/when it makes changes to key system partitions, which are normally mounted read only for obvious reasons.
Most rom images will include a sample de-bloating script,which removes ROM specific branding apps. The script. /sdcard/Proxyme/debloat.sh, shows how this is done and could serve as a base for more extensive clean-up of firmware components, if you so desire.
Operational Notes
Whenever a device boots from a factory reset condition (i.e. after wiping data), there will be no UID/GID list available in the user management screen. The reason for this is that the SuMeD setup process will complete before the app data store, the location where aforementioned list is stored. has been initialised. Restart the device in order to make this list available.
Behind The Scenes
For details regarding how Proxyme's system service components are integrated in a firmware image, please follow this trail...
Device Support
Before taking the next step to flash your phone/device, please be aware of the risks involved with performing such an operation. Prepare the device properly, i.e. sufficient battery charge, and be well informed of the correct flashing procedure(s) for your device's make and model. On Samsung devices, rooting will probably trigger 'custom' flag(s) and consequently render the warranty void. No matter how adventurous you may feel, it is always a bad idea to try to flash a firmware image which is not intended for your device. Having said all that, note that you will be flashing your phone at your own risk. You are solely responsible for anything you do to your phone/device, so make sure you are well informed and well prepared before deciding to flash or install anything on it.
The following list will be updated as soon as new firmware images are prepared for new and old devices.

Proxyme - Behind The Scenes
This section details how Proxyme's system service components are integrated in a firmware image.
If you are not up to speed with how a typical Android system is constructed, then I would like to suggest you at least make yourself familiar with this topic in order to fully understand what to do with the following text.
The system service components are integrated in the /system partition (mount point) in Android. In the case of changing a live system this will require mounting the appropriate partition read/write before applying the updates. If a static firmware image is to be updated, then extract the component which represents the /system partition from the package and apply the updates before re-packing the firmware image.
The following list describes the major system service components:
hijacker - this is a module you need to write, which has the role of initiating the system service in a privileged environment.
hjprepper - this module is started by the hijacker to prepare the environment prior to starting SuMeD
SuMeD - this one is what it's all about. The Proxyme app relies on this daemon to be up and running in order to perform any of its privileged functions
SSHD - the SSH daemon is represented by an updated implementation of dropbear on Android
Hijacker
The hijacker is a program you would normally have to write to replace an existing program in your rom, which is started during the boot process by for example initd. This part of the integration process requires your (creative) input, since you need to analyse the rom you are working on and figure out how and where to position the hijacker module. If you do find an existing module to hijack, make sure to always call that original module from your hijacker once it has managed to execute the hjprepper program. In some roms it suffices to start hjprepper from a shell script, which is run with root access... they exist, you just have to look for them.
This is what your hijacker could look like in C
Code:
#define PROP_HIJACK "proxyme.hijack.system"
#define HIJACKEE "/system/bin/original-program"
#define PREPPER "/system/xbin/hjprepper"
int main( int argc, char *argv[] )
{
char *lArgv[5];
char **lArgList;
int lArgCnt;
pid_t pid;
lArgList = (char **)malloc( sizeof(void *) * (argc + 1) );
for ( lArgCnt = 0; lArgCnt < argc; lArgCnt++ )
{
lArgList[ lArgCnt ] = argv[ lArgCnt ];
}
lArgList[ lArgCnt ] = NULL;
/* Fork parent process */
pid = fork();
if ( pid < 0 )
{
property_set( PROP_HIJACK, (char *)"Hijacker Startup... spawning failed, prep first before xfer" );
system( "/system/xbin/hjprepper" );
execv( HIJACKEE, lArgv );
exit( EXIT_SUCCESS );
}
else if ( pid > 0 )
{
property_set( PROP_HIJACK, (char *)"Hijacker startup... spawned, parent ascends phase 2" );
execv( HIJACKEE, lArgv );
exit( EXIT_SUCCESS );
}
if ( execl(PREPPER, PREPPER, (char *)NULL) < 0 )
{
property_set( PROP_HIJACK, (char *)"Hijacker startup... failed to call prepper" );
}
exit( EXIT_SUCCESS );
}
hjprepper
This program is responsible for setting up an operating environment for the SuMeD daemon. If you have full control over a rom's boot image, then include a call in your init process to start this module once during boot. If not, then use a hijacker program or look for existing and suitable scripts to initiate hjprepper.
hjprepper starts the SuMeD daemon once it completes the setup and configuration procedure.
SuMeD
This bad boy is responsible for the user requested actions through interaction with the Proxyme app.
Prebuilt Packages
To get you started, there are pre-built modules available,which you can download here. Currently, availability is limited to Android 4.3 and 4.4.2 only. The following zip archives are organized in a folder tree structure,which serves as a guide for where to place the modules within the /system path.
4.3 Prebuilts
4.4.2 Prebuilts

Yes. You need to figure out how to get the SuMeD daemon started and that depends on the rom you want to integrate it in. The Behind The Scenes post highlights what areas to focus on when doing this.
Note that the first post includes 2 firmware images (both Android 4.3 and 4.4.2) for the international Note3 (SM-N9005). It's a no-brainer to copy the files from the appropriate directories to an equivalent and same level version firmware for another region of the same device.

Has 4.4.2 been released on that device? If yes, a download link for the official stock firmware will help speed up the process. If not, then we wait or you could send a PM to davidcsv with the 10 or 11 digit s/n and he will monitor and download the latest release as soon as it becomes available...after that your new firmware image will be uploaded within a day.

Apparently, this firmware image is a pre-release/leaked image and not the final deal. It includes an updated bootloader and related components, meaning that it will not be straightforward to revert back to an older version of the firmware. If you encounter problems with this Proxyme preloaded image, then I'd suggest flashing the image from the original download link.
All feedback is welcome and will be appreciated. Enjoy!
Thank you very much. I ask you to add proxyme in I337 4.4.2 rom. Thank you very much.

Please post the complete log from the message box in Odin. One more question, is your phone 16GB or 32GB model?
update: and also try again with newer version of Odin v3.09 instead of v3.07
Inception is a set of tools for auto configuring android devices. You can do the following:
Include any apps to be (pre)installed
Remove any stock apps
Root the device
Install busybox
Configure Wifi networks
Generate all device settings
Patch APKs
Replace Kernel, and/or ramdisk data in both boot and recovery imgs
Place your adb keys, configure USB debugging
You specify all this in a JSON config file. And then inception creates the following depending on what you specify in your configuration:
OTA Update Package that applies all your changes once installed
Modified recovery img
Modified boot img
Cache img that bundles the update package and instructs android to install it once in recovery
Odin flashable tar.md5
With the right configuration, you can also generate auto-root update packages, or update packages that just install busybox, or both.
Code:
incept autoroot --code samsung.degaswifi
or
Code:
incept busybox --code samsung.degaswifi
Or out of a stock recovery img:
Code:
incept autoroot --code inception.device --recovery /path/to/recovery.img
Inception does not create a full system image or compile roms. It bundles only the required changes in an Android update package and generates an update script which applies those changes. This results in update packages that are substantially smaller than when flashing a whole ROM.
As an output example, I posted this Samsung SM-T230 auto-root package, and another Samsung SM-T113 auto-root package that were both generated using inception.

}
}
edit: found the README.md but it is a lot of information. can you please post minimal steps how to create a tar.md5 from adbkey.pub?
1. install linux
2. add packages (requirements)
3. download and install inception (at this point it fails with exit 1 older version of dulwich)
4. incept bootstrap?
5. pass the adbkey.pup to json?
6. incept make?
7. generate odin package??
8. ... ?
