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
