i have the android 2.3 superpad 3 and like upbeatpaul killed my screen. tried holding the menu and back panel buttons but didn't work. don't know if i just press both and release or hold until screen lights up. do i press power button first then the other two or all three at the same time? also tried the mini hdmi and that did't work. also tried just holding menu button and then powering up. still nothing. Need to reset to factory. any ideas?
