I am able to turn on my device and after waiting a few moments, i can unlock the screen. I am able to make a few clicks to change screens, then the device simply quits responding! it totally just freezes up and i am unable to use it. It is a Sylvania 7" Mini Tablet which came with the android 2.1 OS. I have clicked the reset button several times as well as tried the tip for doing the factory reset in the instructions in that thread and i still cannot get this to work. If anyone can pleeeeeeasssssssssse help me figure out this problem i will be very grateful!
