Dear community,
Couple days ago, my phone stop working and rebooted itself, I just discovered this when I put it off of my pocket.
Thinking that it was about I pushed a button when I was seated, I do not worry and let the phone booting.
After several minutes, no boot, just the LineageOS animation, and the phone finally rebooted itself to EMUI recovery telling me "Data partition severely corrupted".
I rebooted in TWRP, it took long time, and after having the control, checked the data partition.
TWRP was unable to mount the partition, any action to recover it failed.
So I used Terminal to launch fsck.f2fs tool to try to recover the partition, no way.
The tool told me that there is no error other than the last line "[FSCK] Other corrupted bugs [Fail]" it propose to fix the issue, but still, no possibility to mount it.
data partition is F2FS type, so using e2fsck could not be used.
After different attempts, I finally formatted the data partition, losing my data was not really a big deal. But TWRP failed to do this action, and the only solution was to let the phone booting, falling back in EMUI recovery and use the factory reset function.
After that, I rebooted in TWRP, data partition was here, able to parse it.
So I reformatted with TWRP, to remove potential bloat tools and data pushed by default from EMUI.
I rebooted the phone, normally it take a long time during the first boot, system configuring first startup and deploying default app.
I let the phone trying to boot for several hours, the battery was totally drained.
I charged the phone, let it rebooted under charge, and...... fail.
Rebooted to TWRP, checked the data partition, some folders were created, so the intiial startup seems to done something.
Reformatted data partition ad tried again. No way.
So today I am stuck in first boot step, LineageOS animation.
I think that my eMMC is dead, and the system could not copy/write something at a specific place, implying this situation.
I do not know if it is possible to copy the last boot log, connecting the phone when it is under TWRP should allow MTP transfer right?
Where I could find any relevant information?
@AltairFR?
Thanks for your feedbacks.
