[Q] Nexus 7 2012 Wont boot after update
I have been working with Android for a few years now. My Nexus 7 has no problems. A friend tried to update her 7 to 4.4.4 via the standard system update. Hers was completely stock, not rooted, not unlocked. She ended up stuck in the bootloader afterward.
The bootloader is locked. When I try to unlock it I get the following error.
(bootloader) erasing userdata...
(bootloader) erasing userdata done
(bootloader) erasing cache...
(bootloader) erasing cache done
FAILED (remote: (unknown error code))
finished. total time: 5.299s.
I have tried 2 computers, 3 usb cables. I have tried WUGS toolkit as well without luck. Nothing seems to get this bootloader unlocked.
Is there anyway to flash the factory files with a locked bootloader?
Any other options?
