recoveryfilename. It was run as root)
Note that the recovery is unusable--resulting in the error message:

Attempt to factory restart the device in the normal manner (via settings)

Using the fix for said problem as detailed by post #21 (by
- Result: Goes all the way to just after the tablet is plugged in and crashes (blah stopped working)
Obviously, bricked devices are never nice. Does anyone have ideas on how to fix it?
