Yoga Tab 2 Kernel Compilation

Has anyone else made any serious attempts at compiling a kernel? Prompted by doctorow's thread about the wakelock issue, I got interested in compiling a kernel so it could actually be fixed. For anyone who's tried at all, there are obviously some missing files in Lenovo's release.
I tried copying over the missing files from ASUS's Zenfone kernel release (since it uses the same SoC and their kernel had all the files that make was complaining about). Between that and commenting out some references to a nonexistent tablet_config.h header, it managed to at least finish compiling. Unfortunately I don't have a bootloader-unlocked device to test on yet, so I'm not terribly confident that it actually works.
P.S.: I'm not really sure if this belongs in the dev section or not? Sorry if it's in the wrong place, but I can't start threads there anyway at my current post count.

Interesting, I haven't even gotten that far when I tried to compile them. The sources are most likely not up to date or even representative of the actual firmware kernel. For example, when I looked at the battery driver, I noticed in the published sources, the polling interval was hard-coded in such a way that it would completely ignore the setting of the poll_interval kernel parameter. But we know that this is not true for the actual firmware which is in fact respecting the setting of said parameter.

@Grarak and me have managed to get the messy "source code" of Lenovo to build. I have additionally added some security patches and stripped some kernel modules. Since we don't want to violate the GPL like Lenovo, we have pushed the kernel to GitHub.
Bear in mind that there may be some issues, given the kernel is a work in progress. It boots on stock as well as on cm-12.1, though.

Same kernel works for both 830f and 1050f?
Could you please post a compiled kernel? (which I assume can be flashed simply via fastboot)
Thanks!

Sure, here you go: kernel-yt2-20160327.img. I think it will boot on 1050F.

Hello, I have a 1050F too is somebody tried this kernel on 1050F? Is it possible to support wake gesture kernel extensions with this kernel?

I was able to unlock bootloader, install TWRP and flash this kernel via fastboot on both 830F and 1050F.
It works fine (and the battery life seems better since there's no wakelock bug).
Thanks!
Looking forward to alpha-grade CM....

Did you use.
Fastboot Flash recovery recoveryname.img.
or
Fastboot flash boot bootname.img
To send it to the tablet.

The kernel goes to the boot partition. So 2nd option.

Using windows? paths are c:\directory\file and not c:/directory/file
I used the fastboot executable from the tethered recovery package.
Checklist:
Did you unlock bootloader? it won't boot otherwise.
Did you backup current boot partition from TWRP/CWM?
Did you boot the tablet in fastboot mode? (down+pwr)
Can fastboot detect your tablet? (fastboot devices)

Yes to all.
I wondered if the command slashes were the right way / or \ the way I used is what I used to unlock the bootloader and install TWRP.
I have tried the slashes the other way and get the same result, as in \ .

Hmm, I'm getting a high battery_wake_lock (on the April OTA firmware) -- even when running this kernel!
Any idea how can this be?

Hi,
I was trying to play a little bit with kernel provided by @Olivier and @Grarak ...
1. Binary Image kernel-yt2-20160327.img boots up fine on 1050l, but LTE is not working. Rest seems to be fine...
2. In next steps I replaced initrd.img with a little modified stock one - and LTE started to work - I removed from initrd almost all modules leaving only bcm43241.ko.
3. Battery wakelock problem seems not be resolved - brief check at bq27x00_battery.c in repository shows that wake_lock is still set under bq27x00_battery_suspend_resume()
... so I trying to fix this battery driver but I have problem with kernel - I can compile it successfully, but it doesn't boot
@Olivier:
1. Which branch was used to build kernel-yt2-20160327.img?
2. Which config did you use ?
My procedure using android-ndk-r12b toolchain:
# git clone ...github.com/lenovo-yt2-dev/android_kernel_lenovo_baytrail
# export PATH=~/android_yoga/toolchain/bin:$PATH
# export CROSS_COMPILE=x86_64-linux-android-
# export ARCH=x86
# make cyanogenmod_YT2_10_defconfig --- if this right config?
# make -j8 ----- lot's of warninigs, but kernel is compiled sucesfully.
# abootimg --create boot_test5.img -f bootimg.cfg -k bzImage -r initrd.img ---- bzImage from arch/x86/boot
> fastboot.exe flash boot boot_test5.img
... kernel stuck somewhere, it's doesn't even come to Zygote phase (lenovo animation). Is there any way to see kernel boot messages ?

Hi
I would also like to experiment with the Kernel, but I need to unlock the bootloader. unfortunately the thread is deleted files and I can not, can anyone help me even for private?
I have a 1380F in KitKat
Kind regards

I used this procedure: mobility.forumsee.com/a/m/s/p12-9574-0973888--yoga-tab-unlocking-daaa-deee-daaa-dooo.html
Patched ESP file I found on another forum: forum.android.com.pl/topic/259763-odblokowanie-bootloader%C3%B3w-yoga-tab-2/#entry4598175
For me it worked on Lolipop, but I as know bootloader changed arch x32->x64 during Lolipop->KK upgrade... I don't know if this esp will work on KK (at least do backup of ESP and boot partitions before).
---------- Post added at 12:07 PM ---------- Previous post was at 11:52 AM ----------
BTW: I was able finally to compile and startup my modified kernel using CM building engine from this thread .
I removed all wakelock code from bq27x00_battery_x8.c
For 1050L I merged: kernel from @Olivier repository + my patch on bq27x00_battery_x8.c + my initrd based on stock + stock Lolipop.
First tests seems to be very promising:
- finally NO battery_wakelock in Wakelock Detector
- LTE is working
- GPS is working
- Sound system is working
- No crashed till now
If anybody is interested i can attach img file.

Thx :good:

The kernel should be working, but the ALS is broken (seems to be a sensor from Avago) - you'll notice that if you use automatic brightness.

Fixed. That was quite easy. Driver al3320 was in place. The problem was permissions set by script init.byt_t_ffrd8.rc in initrd. By default it's root/root, but it should be system/system. I already corrected paths and checked it - it's working. If you could give me permission to repo I can push the patch.
BTW: I see lot's of things are being hard-coded into initrd scripts. Since we changed config kernel, all those scripts must be checked. I can try to do it in free time...but some things are platform depended so, another original initrd from lolopop on 830f would be nice to compare...

Lineage OS (official nightly) installation problem

I was trying to flash official lineage os downloaded from official website through twrp but ended up with an error i can't figure out what to do of. i am uploading screenshot of twrp. help.

Are you coming from Cos 12.1 ?
Than you need to flash ZUI 2.5 ROM first or cm-13 ROM .
Because even if you flash nogout some problem like sim1 will stay always active and sim2 will be greyed out.

i am on zui 2.3.045

Error 7 is caused by the custom recoveries. It occurs both on CWM and TWRP. Just wipe the whole phone and via ADB boot it to recovery (Command 'adb reboot recovery' -- without quotes.) Then copy the ROM to internal storage and now flash. It will work like a charm.

Huh? How will that help? Why do need a 6.0 M ROM before you flash nougat? You can't dirty flash Lineage. It'll end in a boot loop. You have to wipe and flash. So how will the ROM that was installed before influence nougat flash?

LineageOS 7.1 for SGP771

Hi. As a result of Androplus stoppage of his kernel support I decided to create this theme. I'm not a developer.
I use LineageOS more than two months, and it's stable. Originally it was built by andralex, he didn't create this threat as he was waiting the permission from other developer whose groundwork he used. But I lost contact with him. Seems he is very busy.
Now the other developer builded the rom, his nickname is kv123.
--------------
To get usb otg working use this in terminal when you inserted usb stick
Code:
su
echo 1 > /sys/module/qpnp_smbcharger_extension/parameters/start_id_polling
------------
After any lineageos update dont forget about play store to give permissions for storage. Otherwise it wont download any apps larger the 20 mb.
Lineage camera is a bit buggy, so it's better to use open camera.

Some screenshots:

Oh. You need also replace wifi calibration file here: /system/etc/firmware/wlan/bcmdhd/bcmdhd.cal and reboot
It's forgotten to be added.
Updated fixed version at yandex disk.

Thanks for this. It is exactly what I am looking for and I hope my tech skills are up to the task.
BTW, this link comes up "404 not found. Can't find it!"

Would you have another we can try?

Thats because kv123 removed version with wifi buggy.

Why do you use androplus recovery? Use normal recovery, take it from yandex disk. And boot by vol- and power till it vibrates.

Nothing happens after I flashed the recoveries from yandex disk（both 3.0.3 and 3.1), so I tried androplus recovery...
Is there a modified boot.img for those recoveries?

Maybe it's better: fastboot flash recovery twrp.img ?
This twrp only requires updated bootloader from 7.0 stock.
Also i need to keep these buttons pressed untill it vibrates that is 2-3 seconds.

Also you can try to contact with andralex8. He has just 712 tablet. And it worked for him. But I'm not sure if he answers you quickly.
If you keep trouble with the recovery, try twrp from this https://forum.xda-developers.com/z4-tablet/general/guide-nougat-drm-fix-root-twrp-sgp771-t3555265

Sorry if I have missed something obvious, but are you attempting to flash LineageOS? In which case I am confused as to why you are flashing the Sony Rom 32.A.2.33?
For my part I am gearing up to attempt the LineageOS install but would like to have a backup copy of the Sony firmware in case it goes wrong.
Assuming you installed an English version, which one did you select from here:-
https://xpericheck.com/device/SGP771

Indeed, if you try something especially unchecked, better to have a backup.
But you also need to have last sony rom(any of android 7.0) in order to update bootloader and have last twrp working.

Androplus‘ recovery need a modified boot.img so I wonder if the same as the recovery in yandex disk?
And recovery from https://forum.xda-developers.com/z4-tablet/general/guide-nougat-drm-fix-root-twrp-sgp771-t3555265 is the same as Androplus’ recovery.

Ok. If you've done everything right I guess 712 dosent work with 771 recovery. I'll tell about it to kv123 and you can say it on your own on 4pda.

Please anybody who has 712 model. Test 3.1 recovery from yandex disk and confirm or contradict if it dosent work for you.

Thanks, I was connected to WIFI but the issue was solved after inserting sim and connecting to Mobile internet.
Now I am facing a new issue, even after successful flashing of TWRP recovery still stock recovery remains. Any comments?

After flashing twrp, you should boot straight into twrp without allowing the device to boot into home screen at first boot.

Thank you. Followed the instructions. Finally rooted

Moto X pure Boot only recovery

Good Morning everybody,
so yesterday was a rough day and when it eventually end i recive the october security update on the phone, without thinking i installed it and the phone does not boot up , instead i face my recovery (TWRP 3.1.1-0).
Of course i've made a mess because i was on stock rooted 7.0 on my retEU XT1572 phone with unlocked bootloader and status 3
i've tryed to restore a previous nandroid backup wihtout success, so today i downloaded the new RESURRECTION REMIX v5.8.4 (4 december wich is based on stock android 7) but i have no luck even with that...
Do i miss something?is there any rom to try with now? or i have to make a downgrade of my firmware to make it work again?
thanks in advice!
UPDATE:
phone boot now but always in recovery and after rebooting in bootloader i can reboot system from there.. it seems that if you download an update and the install process doesen't go in place every time you restart the device it always try to re-flash it, that's why i'm always in recovery.. i foun a similar post with this solution but i think it need some changes before it will work on our device (but i don't have the knowledge to set it right :S )
LAST UPDATE:
boot fixed by using this command in twrp recovery
dd if=/dev/zero of=/dev/block/platform/f9824900.sdhci/by-name/misc
misc file running at the startup redirecting the boot in the recovery, put blank in the file let the system boot up normally

You missed very much.
Here is stock RetEu, before october update:

2) do i have to flash stock-xt-1572-reteu-7-0-ddumped-files before point 1)?

1. I think so. 3.2.x will be needed for future builds.
1a. You flashed RR for MM modem.
2. No, but this is only way to get ota update.

"swearing in italian" it was a twrp bug.. after a backup restore if you hit restart the phone restart in recovery, you need to boot into bootloader and reboot system from there -.-
thanks to all of you guys!!

strange fact, now if i turn off the phone and again on i'm still on recovery, i have to reboot bootloader and system from there.
i think something is pointing at the recovery instead system..
edit: it seems that if you download an update and the install process doesen't go in place every time you restart the device it always try to re-flash it, that's why i'm always in recovery.. i foun a similar post with this solution but i think it need some changes before it will work on our device (but i don't have the knowledge to set it right :S )

Ota update didn't end.
I think you can try clear data & cache otaupdate app and disable it. Link2sd can help with it. @Husky34

thanks, this command just saved me. but misc file in my XT1575 is under
/dev/block/platform/0/f9824900.sdhci/by-name/misc
but now I can't check system update in the OS anymore, I think flash back factory recovery mine help. Do you know where to download stock 7.0 recovery for 1575?
Edit: found it for 1575 here.

you can also use link2sd to disable the update app so it doesn't bother you,
or wait untill someone create a zip of the update and flash it into recovery.

thanks, that worked for me as well.
