I turned on my tablet this am. It boots and gets all the way to where I should have a home screen but no home screen. The icon bar with home, wifi, time, etc exists but not the rest. I thought I'd try a factory reset since a simple on/off didn't work. After checking this forum and trying a jillion different hardware key combos, I give up. If you've done a factory reset on this model, can you post exactly which key combos you used? Plus, if you need to hold for multiple seconds or minutes?
