How I managed to break my tablet within 4 hours...Just got the tablet yesterday. It was running 1.7.2. I pressed on the empty space till the menu came up, then chose add widget, power control, 3 buttons popped up, picked the rightmost one. The screen turned black. I shut it down. Reboot. android logo came up, screen was good. then android booted, black screen again. Pressed the volume up/down button on top. it made a sound. so android was running, just the screen was down.Any idea how to fix? I'm thinking of flashing the newest firmwares as a last resort. But I'll need to save the account.db file for market store. How can I save files without the screen?
