This morning the tablet was bricked.
When I turn it on, it reports "boot failed" and starts the fastboot download protocol.
I cannot enter CWM recovery anymore.
I have tried to fastboot a CWM recovery with "fastboot boot recovery_nothrills.img" but it gets stuck; I tried to boot the stock recovery with "fastboot boot recovery_1_044_00.img" but it freezes.
I have tried to flash these recoveries with "fastboot flash recovery recovery_nothrills.img" but it fails:
# fastboot flash recovery recovery_nothrills.img sending 'recovery' (5968 KB)... FAILED (remote: (AccessDenied)) finished. total time: 0.016s
I have no idea of what else try.
Is there a recovery program as the one for the A500, running under XP?
