I'm having the weirdest problem with my Nexus 7 and I'm wondering whether it is hardware or software. I have searched everywhere and only found one person with a similar situation and he had already sent his back for repair before anyone responded with things for him to try.
My 16gb Nexus 7 is rooted/unlocked using the Nexus Root Toolkit and at the latest OTA version. It had been working fine for months. Suddenly one day I had serious problems (which I can discuss if anyone cares, but I don't think the original problems are relevant at this point.) I gave up troubleshooting and decided to do a factory reset. But no matter what method I do, the next time I boot the device it comes back into my same buggy system with all my stuff intact and nothing was wiped or reset at all. All of these methods appear to work and give the normal progress messages you would expect, but then nothing changed. It's like the Flash ram is somehow set to read-only so attempts to write to it are failing.
What I have tried:
Settings Factory Data Reset and press the Erase Everything button. The tablet pauses a while, then shuts down and reboots. The old system and all my stuff is still there immediately, nothing changed.
I go into recovery mode, choose function wipe data/factory reset, scroll down to Yes to confirm it. A bunch of progress messages show on the screen that the partitions are being formatted. I boot afterwards and the old system and all my stuff is still there immediately, nothing changed.
.
I follow all the steps in articles like this: http://forum.xda-developers.com/show....php?t=1907796
Every fastboot command completes normally with progress messages showing that it worked. I reboot and the old system and all my stuff is still there immediately, nothing changed.
Here is another clue: The fastboot oem lock command completes normally, but nothing changes. The padlock icon at the next boot is still open.
That's why I say that the tablet is acting as though the Flash memory is set to read-only somehow because nothing ever changes. Is it possible that this is a hardware problem, or is there something else I can do in software?
