here is the firefox APK file so you can have a decent browser on there:
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.
