I am very new to the android parralel scene (and the android and smartphones in general) so please excuse me if I have missed obvious things.
I am trying to do a custom android kernel on a CyanogenMod stable in order to activate SCTP support on a HTC Magic (sapphire) PVT 32B (google branded).
I have followed the this tutorial : wiki.cyanogenmod.com/index.php/Building_from_source to make the kernel (2.6.29-cm42) and this tutorial wiki.cyanogenmod.com/index.php/How_to_build_a_kernel_port for the packing.
My base is update-cm-4.2.14.1-signed.zip
I have tried with my new package as a module (and also redone modules.sqf) and also in-kernel.
I have tried the full update, and I've also tried to patch the kernel on a clean Cyanogen install.
Everytime I get stuck on the spash screen (google io09 developer conference).
Thanks for having read that post!
NB: Before the manipulation I had made a nandroid backup so I can get back without problem.
I use cm-recovery-1.4.img as recovery image with fastboot, and I noticed that I can't use adb to push data on the sdcard and then install it with the recovery. In fact the commands seem to work, but behind the scene it is the old sdcard.zip that is installed. I have to use my backup, fullboot, put my test update on the sdcard, rebootfastmode recover and then install.
Ah also, I would be really happy if you could tell me how to diagnostise errors on the bootphase. I'm currently totally helpless (and that's why I am posting here ^^).
I am now trying to build a new complete cyanogenmod from source with my custom kernel and modules. I don't think it will resolve my problem but I hope it will help me in understanding the problem.
While waiting for my repo sync (that won't end before tomorrow :/) I have made a new attempt at a CyanogenMod mod.
So i recompiled my kernel
Regenerated the modules
generated the modules.dep
Remade modules.sqf using update-cm-4.2.14.1-signed.zip as a base
Inserted wlan.ko and my new boot.img (made with unpack repack) into update-cm-4.2.14.1-signed.zip
Signed with the testkeys from the tutorial
Fastboot
update
Stuck...
I zipped some file if it could be of any help
my .config, zImage, boot.img, wlan.ko and modules.sqf
Thanks for reading
After some irc chat session I discovered it would be possible that my problem come from a bad boot.img generation.
I use old unpack / repack scripts (with whose you can't use the --base parameter).
I will try to fix this now, and retest!
@chrmhoffmann compiled first ever CyanogenMod for his Wiko Stairway which is a MT6589 device and made it possible for other MT6589 users to taste CM. Since then many are porting it to their MT6589 device and many are requesting to make a port for their device. So, I have made a guide here to make it easier for them to port themselves. You should give proper credits to respected developers and hit thanks before posting on XDA.
NOTE:I have made a list of already ported CM roms in #2 post below , if your device is not listed there download any of the ported CM rom and follow this guide to port it to your device
This is the guide to port CM 10.2/11 for all MT6589 devices.Read carefully and follow each step correctly otherwise CM won't boot
Tools Required:
1) Archive Manger (winrar,winzip,7zip)
2) boot.img Unpack Repack Tools
http://forum.xda-developers.com/showthread.php?t=1587411(For Linux)
http://forum.xda-developers.com/showthread.php?t=2036528(For Windows)
NOTE:
For CM 11 the same proceedure is followed but the stock boot.img must be having kernel with binder.c patched and SELinux enabled (This feature can be bypassed but binder.c patch is must otherwise CM 11 won't boot)
Guide:
1) First get your stock rom and download any ported CM 10.2/11 rom from #2 post below
2) Get boot.img from your phone(stock rom) and boot.img from downloaded CM-ROM.zip
3) Unpack both of them to get ramdisk and kernel of both.
4) Repack CM's ramdisk and stock kernel (your phone's) to get a new boot.img
5) Extract system folder from your phone(stock rom) and system folder from downloaded CM-ROM.zip
6) Copy and replace these files from stock to CM,
=> /lib/modules/ -> all files
=> /framework/ -> CustomProperties.jar
mediatek-common.jar
mediatek-framework.jar
mediatek-op.jar
secondary-framework.jar
=> Also all the files mentioned in the below link ( A great thanks to Kashifmin for providing this )
https://github.com/kashifmin/android_device_micromax_a116/blob/master/proprietary-files.txt
7) Now take the modified CM system folder and the new boot.img and make a zip archive with normal deflate compression ( are default in 7zip)
8) Open the newly created zip archive and downloaded CM-rom.zip .Now drag and drop the META-INF and file_contexts from downloaded CM-rom.zip to newly created zip archive.
9) Now flash the new zip using recovery (CWM/TWRP)
10) Enjoy !!

If CM for any MT6589 device is missing here , PM me. I will add here.
i try but always stuck on boot splash, no boot up.. pleash help thanks
Uhm.... I guess I can't port cm10.2 over stock jb4.2.1 rom, right?
I ask because I first looked for cm10.1 to port, but to my surprise, I didn't find any cm10.1 builds for any mt6589 on google.
@polfrank you can port CM 10.2 using stock 4.2.1 rom. First you have to download any CM 10.2 Rom from above and follow guide to port. You can even port above CM 11 Roms if you have a working kernel source for your device

@limam27 boot loop occurs if 1) boot.IMG is badly repacked 2) any file is missing from your device stock rom which has to be copied to CM ROM as mentioned in the guide. Check them first . Also Check whether you are getting errors during unpack and repack of boot.IMG.
Sent from my iris458Q using XDA mobile app
Hmm, I'm stuck on my brand's splash screen too. I don't get to see the boot animation, and as you mention I get errors during both unpacking and repacking. But it said that the file was copied though.... I 'll search for another way to upack and repack on Google and come back.
Edit: pfff, seems like the only way to do it on windows was the one you provided...
Which CM version you are trying to port ?
If have Linux use unpack scripts to unpack/repack boot.img
Windows always gave me errors.

I chose the CM10.2 from Wiko Stairway.
Yes, I'm now setting a Virtual Machine with Linux 14. And I'll try the unpack scripts from there. Let's see...
UPDATE:
OK, i ended up doing a clean install of ubuntu.
I upacked both images SUCCESS.
I repacked using stock kernel.img and CM ramdisk folder, SUCCESS.
I Install boot.img through CWMrecovery, it now gets past boot logo(Cubot white screen) but I think that before it would enter bootanimation the screen becomes a weird mass of colours, as if the screen was broken. It lasts for 1 second, then it restarts.
ps. I can successfully go to recovery with power+volUP If i like..
Any ideas?
You should get CM boot animation even if you use stock boot.img but won't boot. Did u correctly replace all required files in rom ? Do a clean one. Check if you can get logcat. Send me the logs

I think I used wrong kernel.img. I repacked, will flash soon and come back to report.
EDIT: Are you sure that I have to use the META-INF folder from the CM rom? It gives me status 7 error.... (I also used the META-INF from a rom for my device, unfortunatelly it uses aroma, but it seems to install properly..)
EDIT2: I think that now I repacked the correct components of boot.img. It seems to get past the Cubot white splash screen, but after this, I get a black screen, but I can see that the screen is on, I can see the backlight. [I will try again with the CM META-INF-->still fails]
ps. Seems like I have to learn how to get a logcat if I wanna make use of your help... I'll be back in some hours.
----------------------------------------------------------------------
To sum up:
I have packed the new boot.img and replaced the needed files in the rom.
1) With the CM's META-INF folder I can't install, status 7 error.
Finding update package...
Opening update package...
Installing update...
assert failed: getprop("ro.product.device") == "stairway || getprop("ro.build.product") == "stairway"
E: Error in /sdcard/experiment/cm102last.zip
(Status 7)
Installation aborted.

2) With the stock rom's META-INF it seems to install propperly.
After reboot from recovery it goes to a black screen and stays there. I tried to logcat (adb logcat -v long > port.txt) but it just says:
[email protected]:/home/pol/Documents/sdk/platform-tools# adb logcat -v long > port.txt

CONCLUSION: I managed to install the new boot.img and rom but it stops on a black screen, right after it passes from the white logo screen. And now, I need your ideas...
ps. I repeated the porting process from the beginning to make sure that I didn't make any mistakes... again, the same result.

NEW UPDATE: IT BOOTED!! but how....? Here it is........
I just replaced the boot.img from the wiko stairway flashable zip with the boot.img I created with repacking my phone's kernel and CM's ramdisk.
SO, I just changed the boot.img !!!! Testing.......
-------------------------------------------------------------------------------------------------------------
Testing results: buggy mobile network and sound not working. I guess this is why all those files are needed to be copied. I think I ll start copying..... But I wonder...what did I do wrong earlier while copying,,,?
You will get status 7 error because it is a security feature which doesn't allow to flash one device's ROM to other. You have to edit using any text editor and remove first line in the update-script found in meta-inf/com/Google/android/
Also don't use other rom's meta-inf as they have different symbolic links which may not boot the device.
Your phone's modules will be different from wiko's. That's why you got buggy audio and network. Replace all the mentioned files.

Okay, after some hours of trial and error I copied all the porting files provided in the op, except 2:
-libjpeg.so - When I port this from stock, Cm boots, but cannot show images, every single image, including the bootanimation is black.
-libmedia.so - When I port this from stock, Cm stays in the bootanimation forever. (No bootloop, just bootanimation forever)
-------------------------------------------------------------------------------------------------------------------------------------
The "extra" bugs that I have are:
1. No sound from the speaker (but yes in the headphone).
2. Weak signal. I don't know if this is normal. It has 1 bar and sometimes it has 0 and says no service. Also, the name of the tile in the QuickSettings is 20201 (weird...). I also get a message when the rom boots and it says: "Restricted Access changed. Data service is blocked." This appears sometimes at random too.
3. USB storage doesn't work through Android.... ( I don't know if this is normal too). When I plug it on PC it just charges. (Note: I now see that other devices have this problem too. I found a partial workaround in the MMX Canvas HD cm10.2 section)
PS. Would logcat help in any of these problems?
--------------------------------------------------------------------------------------------------------------------------------
I moved on, and took some adb logcats.
1. I took the audio.txt as follows: started logcat, pressed play on the apollo widget, pressed pause, stopped logcat
2. I took the signal.txt as follows: started logcat (while on Airplane mode), disable Airplane mode (from quickSettings tiles), enable mobile data, disable mobile data, enable Airplane mode, stop logcat
I'll look at logs meanwhile I never had problem with signal, speaker audio and images. To get USB storage working add these lines to build.prop and reboot
persist.sys.usb.config=mass_storage,adb
persist.sys.usb.config=mtp,adb
For signal issue , did u replace your modem.IMG in CM ROM ?
For image issue try those 2 files from wiko ROM.
Edit:
Try to freshly port CM once again as given in guide with some changes in meta-inf and build.prop as I gave. If you still have problems then report here.
I couldn't debug audio log but in signal log > network is disconnected as data is enabled and even it's saying messaging settings are false. There may be issue with modem.img
sent from my iris458Q using XDA mobile app
Thanks for the USB storage tip. At least the internal SD can be seen now by the computer.
Images are OK now with the lib of CM.
For signal issue I copied modem.IMG from stock into the CM rom, and still having problems.
Btw, I just created a new thread for my device, I hope this is not a problem.
http://forum.xda-developers.com/and...cubot-gt99-t2834832/post54542482#post54542482
Cheers !! I'll add your device in the ported list. As I said previously all necessary files should be replaced in CM to be bug free except major BT,camera,hwcomposer,FM,GPS,2nd Sim bugs.
Also USB storage is buggy now as SD card is unmounted in mass storage mode but not mounted on PC and when disconnected from PC it doesn't get mounted and you have to reboot to get it working on android. Also mtp mode sometimes doesn't work

Nice!
The only file missing is /lib/libmedia.so and I 'm starting to think that this may be the cause of the sound bug. But when I copy it from the stock rom, I get boot problems...
Anyway, thanks for your help, and sorry that I messed up/spammed your thread. I think the most important part of the job is done..! Good job!
EDIT: I think I sort of fixed the mobile network issue. I used a modem.img from another version of stock rom and it seems to work. However I still get the error "Restricted Access changed. Data service is blocked." But I have full signal and 3G! It's something!
Restricted access notification occurs if you enable or disable data and turn on/off airplane mode and phone and it is not a issue I think. It may be cyanogenMod's security message or something.
Also try libmedia.so from other
Stock rom which you said above.

You can't patch binder.c from boot.IMG. You must be having kernel source for your device and you must patch binder.c in kernel. If you don't have kernel source then its almost impossible to get KitKat. See if your device clones have kernel source for their device. Else look for almost similar specs device with same processor. My device has mt6589m but no source from vendor. I used similar mt6589m device's source to build kernel. Now CM 11 is booting but no display due to different GPU config. So it's really hard if you don't have source. Try with CM 10.2 first .
EDIT- Previously I have told why you get status 7 error. So read whole thread before posting here. Good luck

The microphone is also not working in all apps (except Telephone where it work's fine) in the original CM12.1 by fire855 for the Kingzone K1. (The Rom this Porting Guide is based on).
That could be part of the problem.

I'm still struggling to port this rom to DG550.
1. The tool you used to extract the kernel does not work in Windows 8.1 and Windows 10 (I got empty RAMDISK folder). So I switched back to Windows 7 and it worked well.
2. Compared both Ramdisk folders in Stock DG550 Kitkat and Stock Kingzone K1 Kitkat boot.img's.
There is no difference except in ueventd.rc file. I tried to mix DG550 kernel and Kingzone Z1 stock Ramdisk with DG550 Kitkat rom. It didn't boot at first. The problem was in ueventd.rc file. See line 152 (Mali Node). After replacing ueventd.rc file from DG550 ramdisk it booted and worked well (stock kitkat rom). So both the stock ramdisks are identical if ueventd.rc file is replaced.
3. But it fails when porting the boot.img for CM12.1. Theoretically CM12.1 ramdisk should work with DG550 kernel for CM12.1 rom without any changes (except ueventd.mt6592.rc). It does not pass the boot logo.
4. Also I noticed that there's some issue in sbin folder in ramdisk.

There is no difference except in ueventd.rc file. I tried to mix DG550 kernel and Kingzone Z1 stock Ramdisk with DG550 Kitkat rom. It didn't boot at first. The problem was in ueventd.rc file. See line 152 (Mali Node). After replacing ueventd.rc file from DG550 ramdisk it booted and worked well (stock kitkat rom). So both the stock ramdisks are identical if ueventd.rc file is replaced.
3. But it fails when porting the boot.img for CM12.1. Theoretically CM12.1 ramdisk should work with DG550 kernel for CM12.1 rom without any changes (except ueventd.mt6592.rc). It does not pass the boot logo.
4. Also I noticed that there's some issue in sbin folder in ramdisk.

Please let us know if u can let it boot
Ramdisk sBin shoudn't be a problem, if they really cause trouble, try copy the missing files from base dg550 kk to cm12

How to solve storage bug??
Device booted.Not able to mount/access storage. ??
Warning: SELinux – important security feature.
After disabling it you obliviously make Android less secure. Use it on your own risk.
Why it needed?
SELinux can prevent work some mods, like Viper. Or you can have own reasons.
Executing in Terminal "setenforce 0" or via scripts / apps turns SELinux off only after booting: this is not good.
This solution disables SELinux directly in kernel.
Compatible with any MIUI or custom ROM.
How it works
After flashing ZIP creates kernel dump, then it repacks with new command line androidboot.selinux=permissive and writes back.
Into /system/bin copied script.sh and two binaries: mkbootimg and unpackbootimg plus auto-restore script (addon.d)
Last required for keeping and launching that files at every ROM update. This works only on custom ROM's, on MIUI you need re-apply patch manually.
Note: on previous phone at some rare unknown conditions after updating ROM kernel repackaging ended with error and device can't boot.
In this case enter recovery and restore boot from backup or flash boot.img from ROM via fastboot / TWRP.
How to install
1. Once flash attached ZIP
2. Then flash required mods
How to delete
1. Delete file /system/addon.d/99-selinux.sh (and other, that belong to mods that not work with SELinux)
2. Flash current ROM
P.S. This patch probably will work on any device (at least with custom ROM because stock kernel can use different structure).
Rare, but may be required change path to boot partition in script.sh: /dev/block/bootdevice/by-name/boot, twice.
Hi does this method still work in Android 10 and newer?
Great job. This is exactly what I was searching for!

Very likely, don't know for sure because still on Pie. Try yourself and share result
When I run this command:
Code:
cat /proc/cmdline
I get this result:
Code:
BOOT_IMAGE=/boot/vmlinuz-5.0.0-13-generic root=UUID=XXXXX-XXXX-XXXX-XXXX-XXXXXXXXX ro quiet splash vt.handoff=1
Maybe in Android 10 and newer they moved the androidboot.selinux=permissive parameter to somewhere else kind of like how they moved the system partition into the super image?

Parameter not present by default.
It's not clear if you tried to flash ZIP. If yes and got no result: probably script can't handle changes in boot.img structure because it was created 4 years ago. Try some tool on PC to unpack boot and add line manually.
Here is a few boot.img files (tarred for Odin and zipped) intended to be used together with GSI systems (e.g. LineageOS) which suffer from the non-functional touchscreen after the wake-up and the non-functional MTP (USB file transfer). The boot.img files contain the recompiled stock kernel taken from Samsung Open Source with only a couple of the most necessary fixes. 99.9% unaltered, 100% open-source
All credits for the touchscreen fix go to manteiga25, he's done an amazing job on figuring this all out, still from his solution which includes additional performance tweaks I've taken the absolute bare minimum so that the problem is no longer present. Also huge thanks to Osvaldo Costa for the wonderful bootimgtool.
NOTE: If you did not yet flash any non-stock boot.img or recovery.img you may get the bootloop after flashing of any of these files (except for the orig's). That bootloop is caused by bootloader refusing to boot the VB-unsigned kernel together with the rest of the VB-signed components. The only solution (unfortunately) is the full factory reset, so you'll have to lose your user data; everything else, including the GSI will remain intact, but you'll have to set it up from scratch.
UPDATE 01/09/23: added the version based on A127FXXU7CVL2 (Android 13) version of the kernel.
UPDATE 01/11/23: added the fixed kernels for SM-A125F.
UPDATE 03/16/23: added the version based on A127FXXU5BVF3 (Android 12) version of the kernel.
Files for SM-A127F:
boot_sm-a127f-u4_fixed.zip: A127FXXU4AUK1-based kernel, Ilitek ili9881x fix, MTP fix
boot_sm-a127f-u5_fixed.zip: A127FXXU5BVF3-based (Android 12) kernel, Ilitek ili9881x fix, MTP fix
boot_sm-a127f-u7_fixed.zip: A127FXXU7CVL2-based (Android 13) kernel, Ilitek ili9881x fix, MTP fix

orig_boot_sm-a127-u7.zip: the original unaltered A127FXXU7CVL2 boot.img for undo
src_sm-a127f_fix.zip: all the altered source files
Files for SM-A125F:
boot_sm-a125f-u2_fixed_v1.zip: A125FXXU2BVB4-based kernel, Ilitek ili9881x fix, MTP fix
boot_sm-a125f-u2_fixed_v2.zip: A125FXXU2BVB4-based kernel, Ilitek ili9881x fix, Novatek nt36525 fix, MTP fix
orig_boot_sm-a125-u2.zip: the original unaltered A125FXXU2BVB3 boot.img for undo
src_sm-a127f-fix_v2.zip: all the altered source files
v1 should be easy on battery, but v2 will probably eat more because it basically disables the power saving features of the touchscreen chip (unfortunately that's the only solution at the kernel side).
If you don't trust me or if you're in desperate need of a more recent kernel, here are the steps how to rebuild it all yourself (for SM-A127F on Debian 11):
Download the kernel source from Samsung Open Source (A127FXXU3AUJ5)
Unpack SM-A127F_RR_Opensource.zip and Kernel.tar.gz inside
Unpack SM-A127F_RR_Opensource_A127FXXU4AUK1.zip into the same dir (overwriting the files)
Unpack the attached source.tar.gz, it contains only the changed files and build.sh facilitating compilation
From root: apt install clang-9 gcc-9-aarch64-linux-gnu
Remove any other versions of clang. Then cd /usr/bin; ln -s clang clang-9; ln -s clang++ clang++-9; ln -s clang-cpp clang-cpp-9
Back in the Kernel dir, run build.sh and wait for the kernel to compile
Download bootimgtool and compile it (just "make")
Download the stock firmware
Extract boot.img from AP_A127FXX[...].tar.md5 (unpack using tar, ignore the .md5) to the root dir of your Kernel
bootimgtool disassemble boot.img
cp Kernel/arch/arm64/boot/Image kernel
bootimgtool create -o boot.img
Flash boot.img as is using Heimdall or pack into .tar and flash using Odin
For SM-A125F you'll need to use the Google's patched Clang and GCC instead, and there is no way around that except for lots and lots of additional include paths for the Mediatek drivers (and even that does not guarentee that it will be compiled successfully).

Amazing work. Love to see developers still working on this device. Does it work with SM-A125F?

You can try, it may work, but most likely will bootloop. SM-A125F is based on a Mediatek SoC, SM-A127F is based on Exynos, which has a different kernel config.

I don't want to risk it as it is my main device and don't want to have to restore the device later on. Thanks though.
I've finally managed to compile the SM-A125F kernel (A125FXXU2BVB4 - SM-A125F_EUR_RR): somehow it turned out to be MUCH harder than that for SM-A127F, as nearly everything there is designed for only one specific toolchain, plus the non-Samsung s_mtp driver did not compile, so I had to take it from A127F's source. Anyway, I've ported the same fixes and here is the experimental boot.img. As I don't have SM-A125F I cannot test it, so I need someone to test it. Also attached is the original U2 boot.img: in case it does not work you just flash the original.
Amazing bro! Mad respect!!!!
I will soon put this baby to the test and see what's made of!!!
I can flash this using ODIN (PDA) directly over the current LOS GSI right?
Also, do you plan to include this kernel in your gsi building script so that the boot img of the gsi will be this one?
One other issue that I seemed to also have in my phone was the proximity sensor was not working e.g. when I was in call the screen would remain on....

Yes, flash using Odin. GSI should not be affected in any way. If anything does wrong I've also attached the original A127FXXU4AUK1 boot.img, so that you could revert the changes.
Currently I'm struggling to make the same fixed boot.img for my second phone, which is SM-A325F, and I cannot: even if I just unpack and repack back the same boot.img using any tool, including the Google's official mkbootimg, it causes the bootloop. So all of this is currently experimental.

This issue is sorted out: one cannot flash a custom boot.img over the signed stock one and don't do the full factory reset afterwards. Only after the factory reset the system boots with the unsigned boot partition. Interestingly enough, Download allows flashing such an image without any warnings (in contrast to flashing up_param.bin) but the system just refuses to boot.

There is no physical proximity sensor in this phone, but with the latest firmware you can normally use the Phone app. Now it normally reacts on touching the top part of the screen with your ear and blanks the screen. The screen does not blank on approaching the screen but only on touching it.

Done! ) See the update in the first post.
I've used the A127FXXU7CVL2 version source but it should work anyway because it's also U7-based (anyway there is no alternative - Samsung provides only that U7-based kernel). The only thing that theoretically can be needed is the factory reset: at least with my SM-A325F that was the case of the weird boot loop - the Verified Boot protection being voided (the warranty void bit being set) caused the bootloader to refuse loading the kernel.
