I have been having problems with my t301. The screen was not responding. I tried reloading updates,formatted and retried using sd cards, and even tried the alternative method by downloading the debugging utility and teathering the device to my computer. Nothing worked. It would go to the unlock page and when touching the screen it would not react. Long story short. I took it apart and the ribbon connecter from the touch screen was just loosely sitting in the connector on the circuit board. The clip was never snapped into position when it was manufactured. I simply snapped the clip closed and made sure by pulling on the ribbon. works perfect now!. I almost threw it away. Maybe this can help someone out there.
