[skoczo]

Hi. I had lineage os installed on my phone. Now i want to restore it to original. I can flash original firmware from there https://developers.google.com/android/images#occam without any error. The problem is during boot. It boot endless. I wait couple hours without any effect. I installed twrp and check partitions but it looks ok

Do you have any idea what is wrong?

If your stock firmware installed correctly you shouldn't have root any longer. How did you install TWRP? How did you install your firmware? flash-all.bat?

So when i figure out that stock rom don't want to boot i installed twrp from command line by

sudo fastboot flash recovery twrp-3.5.0_9-0-mako.img

to check partitions.

I installed stock rom by executing

sudo ./flash-all.sh

I see that i have 16G version but from partitions it looks like 8G version. Can it be a problem? How to restore partitions to original?

Your firmware should take care of everything. Did you edit the flash-all.sh? Take off the -w?
I've never used sudo before when flashing mine.

No i didn't edit files from google. Sudo is needed for fastboot execution on my system(manjaro). Then this command is run with higher privileges.

Have you tried a factory reset from within TWRP?
It's been a while since I've had a working TWRP.

I have some progress. I run stock firmware but with some additional steps. This is what i did:
- install stock rom
- install clockwork or twrp
- boot to clockwork
- start `adb shell`
- execute `mke2fs -b 4096 -T ext4 /dev/block/mmcblk0p23` in shell

But if i flash it again i need to do this procedure again. I don't understand why. I can't also do factory reset in twrp because it shows that can't mount some partitions.

I can do factory reset after calling `mke2fs -b 4096 -T ext4 /dev/block/mmcblk0p23` in adb shell

I started stock android and did some configuration. It looks that system is working. Now as a test i flash stock firmware again and i have boot loop again. Probably i need do the procedure one again. Do you have any idea why? And how to fix this? i see that cache also can't be mounted after flash stock rom so i did `mke2fs -b 4096 -T ext4 /dev/block/mmcblk0p22` and now it can be mounted. But why i need to do this? Why stock rom is not working? And this happen each time when i flash stock rom.

There is also such thing that if i don't execute `mke2fs -b 4096 -T ext4 /dev/block/mmcblk0p2` after flashing lineage os is showing screen that device is encrypted. Then i need to login do adb shell and execute mke2fs. This is wired that i need to do this every time when i flash device.

I solve my problem by following this instruction https://forums.androidcentral.com/n...3923-guide-nexus-4-factory-image-restore.html

I think that key was those commands:
- fastboot erase boot
- fastboot erase cache
- fastboot erase recovery
- fastboot erase system
- fastboot erase userdata
- fastboot oem lock
- fastboot oem unlock
