I punched in this code: *#*#2663#*#* to update the firmware for my touch-screen and touch-key. When I hit "Touch Key FW update" it updated really fast and everything was great! When I hit "TSP FW update" is said "Now Updating... Warning! Do not turn off!" And it STAYED THERE FROZEN... It said "Do not turn off!" So I left it until the battery died! Then I plugged it in to charge it, and now the back button and menu button BOTH don't work at all! I tried two more times to "TSP FW Update" but it's totally permenantly frozen! I tried flashing the stock firmware! I can't get to the menu to do "factory reset!" What do I do??
