Tablet Factory Reset

As an alternative to the above instructions, you may just want to start with a factory reset.

Install ADB:

$ sudo apt-get install android-tools-adb

Now check that the tablet shows up:

$ adb devices

That should return something like:

List of devices attached

20080411413fc082 device

If the tablet shows up, run this command to perform a factory reset:

$ adb shell "su -c 'am broadcast -a android.intent.action.MASTER_CLEAR'"

This will reboot the tablet, and when it boots back up it will be ready to use.
