Rob Vitale by this "done the on volume button thing " you mean a complete hard reset?


Ok. I hold the on button and hold the volume down button. It goes blank. Then it comes on for 1 second and on the screen it says that the UI launcher has stopped. Then freezes up. I did the same thing with volume up. It's not happening. All I wanted to do is clear the cookies and reset the app. preferences.

Rob Vitale start with a hard reset. You will lose your files like pictures, music etc. when you do this.

You need to hold down the volume up button then press the power button for a few seconds until the tablet turns on, releasing power button, you should now be getting the recovery menu.
