So I got my GSM Galaxy Nexus from Rogers (Canada) 10 days ago. It has been working dandy with maybe 1 force close the whole time and no random reboots. I also unlocked the bootloader and installed 4.0.2 (yakju) keeping the radio that came with it intact. I also installed Google Wallet on it and successfully used it. Other than that, I haven't done any tweaks, and like I said, it has been working perfectly with no problems whatsoever. Enter today: I woke up this morning and went to check my phone. Instantly 3 applications force closed (com.google.process.gapps is one that always quits right away). Now for the whole day, applications force closed (some won't even have a chance to run for a second) and the phone reboots at random intervals.. some as short as 5 seconds. In the time it took me to write this, it has rebooted 5 times. Sometimes it reboots as soon as it has booted up, sometimes it works for a few minutes before rebooting. In any case, the phone is unusable. Every time it reboots it goes back to the same state, and notifies me of the same emails. If I install an app (which I managed to twice or so), it's not there after reboot. If I delete an app, it's there after reboot. (Think Groundhog Day). Now I can't even install apps.. the error I get is "app name" could not be downloaded due to an error. (492) I have no idea how to fix this!! I can't do a factory reset since it just reboots if I try. And I have been trying to re-lock the bootloader (so I can unlock it again and wipe all data) in fastboot by typing "fastboot oem lock", but it just unlocks again when I boot it up. I have tried flashing 4.0.2 again overtop but it hangs while writing. In fact I can't flash anything.. even though there are no errors in command prompt, any time i try to flash anything (radio, bootloader, etc) it stays the same. I've also just gone and deleted files in various directories (like Downloads) to test this, and they always are back after reboot. I have searched all over the internet and it seems like my issue is unique. Could the flash memory be corrupted or something?
