[DEV] LineageOS bring-up thread for Lenovo P2 [P2a42]

[wzedlare]

Isn't working. Same as before

Well, I think it might be from the kernel.I put the stock kernel inside boot.img.Just put the boot.img inside the rom zip an flash it.Don't flash gpu blobs after the rom.Let's see if the problem is from the kernel or not.If its not from the kernel, I will give another graphic blobs zip to try

You can try the graphic blobs again if it won't boot again.

I already tried to change the zimage with the stock one and is the same thing. The only difference is that the phone doesn't reboot into bootloader after Rom flash

If it stucks at logo instead of rebooting to bootloader, we should use new boot with stock zimage.Can you flash this zip after the rom(which includes boot.img with stock zimage).This time we will try msm8952 gpu blobs.If it won't boot again, you should take logcat.

How to take a logcat?
- Use the boot.img that I gave in my previous message.
- Use this code to take a logcat in adb folder.

adb logcat > log.txt

Wait for some time and unplug your phone,then upload and share it with us.It might not be caused by gpu blobs.

Yes let me backup everything and I'll also try your boot.img

I've tried to flash first the rom and your boot.img without any fix and now the bootanimation appears but when appears preparation boot the phone restarts and again the black screen with blue LEDs. Here is the logcat

Well then, I should fix the kernel source.I will fix f2fs.You will try the new kernel with your stock rom.If it boots, then we will proceed to cyanogenmod

I've put the missing imscmlibrary.jar but the phone won't boot. Here is another logcat.I will try the boot.img with the stock rom but after that I have to go. I will be away for a bit.

edit.
The boot.img isn't working on the stock rom. Stucks on the lenovo logo

Keep up the good work!

Idea's for rom will follow, also going to try some tweak development if I can

 

[wzedlare]

I need someone to test CM Recovery, if it works then it means that compiled kernel is working perfectly.By the way my oem will be unlocked after 6 more days It will make it faster to boot cyanogenmod.It is just matter of minutes but my oem is locked and I have been waiting for days for its approval from lenovo.

How to try using fastboot? Just boot it, booting won't replace your recovery, it is just one time trying then you can use your twrp again.

[ilmervanhattem]

Able to test in 3 days... Good work by the way!

 

[ilmervanhattem]

Guys hurry up, I need CM tomorrow

 

[wzedlare]

Guys hurry up, I need CM tomorrow

There isn't any tester except you right now, I am waiting for recovery test.My oem will be unlock after 4 days

Bootloader will be unlocked in about 10 hours. Will test I tonight or tomorrow morning. Cheers

 

[wimmetje]

Here 6 more days for unlocking the bootloader, after that i am willing to test.

 

[ilmervanhattem]

Will the SD Card erase when you unlock Bootloader?

Send from my Lenovo P2 using XDA Premium. Check apk 0day.com or apk0day.nl

EDIT: yes it was erased.

Thanks for trying, problem is not caused by you, I will give another recovery tomorrow.

Got TWRP flashed and rooted, converted to ext4, wiped, and then/but when installing CM error 7 pops up! Talk to you guys tommorow.

EDIT: Fixed! Working fresh original rom with ext4, twrp and supersu! Happy.

You didn't need to test cm, you should just try booting recovery

This time, try booting this one with fastboot boot.
