[Solved] How I got fsck.f2fs to get unstuck and fix not booting PP - gab - 02-07-2022
My PinePhone (v1.2, 3GB running Mobian testing from eMMC) was low on battery and the red USB C cable was not perfectly plugged so it got unplugged, the PP abruptly turned off and ... it would not boot again
. That was the first time ever I got this problem, in 11 months of daily driving (no other phone), and a lot of drained batteries (thats bad, I know...).tldr: to fix it I flashed Mobian on a micro sd card, then fsck.f2fs was not working but after I mounted / unmounted /dev/mmcblk2p2 I retried fsck.f2fs which then surprisingly worked and apparently fixed any problem left.
More details:
First log I got using the UART cable:
Quote:(initramfs) Begin: Will now check root file system ... fsck from util-linux 2.37.3
[/sbin/fsck.f2fs (1) -- /dev/mmcblk2p2] fsck.f2fs -a /dev/mmcblk2p2

The root filesystem on /dev/mmcblk2p2 requires a manual fsck
After that here is what I would got when running fsck:

Then the PP was booting fine

Strange, happened again today.
I got this from booting Mobian on sdcard:

This time, simply mounting / unmounting from Mobian on sdcard fixed the boot of Mobian on the eMMC.
