Hi all,

I have a strange problem on my gnexus, it starts, loads for 1-2 min, than suddenly reboots, bat this is not the real story!

That is only the first symptom, the real problem is that the ROM seems to be writable, but after some amount of writes it rollbacks to the previous state, causing a reboot (all catlogs were different each other).

I have verified this strange behaviour both flashing a new rom or recovery (both frozen at the previous version after the reboot) and deleting some files from the twrp file-manager (files back there after restarting the file-manager), or even simply moving an icon on the home screen (back in the original position after the reboot).

Some ideas there? Some way to do an hard reset? Is this a known failure mode for an SD card? help me please

Thanks all!
Matteo

You must do a full wipe, and then flash new rom+gapps

I did all the possible wipes present in twrp, without any effect... is there some form of hardware wipe?

The problem is that even fastboot has the same write-and-forget behaviour... so no way to update/modify the recovery.

Sorry mate, I think your EMMC is dead. You can test by locking the boot loader. If it's still unlocked on reboot your EMMC chip is fried..
