N7 stick on bootloader, no cache, cant unlock
I have in the past had to come crying on here for you miracle workers to help me so im here again
The nexus 7 unit was running well. I had a few issues with random shut downs and was getting concerned.
what i ultimately wish for is a back to stock factory fresh install nexus 7
after searches found a reset may help
got into bootloader
into recovery and tried a factory reset
the unit stopped at wiping /data
a press of buttons changed this to the android dude with a swirling tummy. Left this to no joy
Started again. this time cleared cache. This had the same error. (just sat there)
Then i got an error indicated the E:failed to mount /cache (invalid argument)
basically E: cant be accessed
So, i decided to look a bit further and unlocking the unit seemed to be the only way i was going to fix this....
problem is it wont let me unlock my bootloader
C:\google>fastboot oem unlock

(bootloader) erasing userdata done

i now have a nexus 7 that will boot into bootloader, recovery
