I purchased this 8 inch A8 Pad Cortex-A8 Google Android 2.2 Tablet PC With 4GB Wi-Fi from Pandawill.com and it was working fine. I purchased a 8gb sd card and tried to use it. Long story short I ended up formating the internal sd card. I now will boot to the Android 2.2 logo then the linux penguin, it then goes to a touchscreen calibration. After touching the five points it then stays on that screen, and the only way to get it off it is to press the reset button. I have left it on that screen for 7+ hours and it will stay in the same screen. Does anyone have any ideas on what I can do? And to make matter worse I purchased it as a gift for my son, so I am hoping to fix it before Christmas.
