Chanchan05: I did that. Removed the card and booted the tablet up. Same problem. I also let the battery run down, plugged it back into the charger and tried the reboot with the same result.
Does anyone know what the spinning robot standing on what looks like a UFO means....that is as far as the boot process goes and just hangs there for as long as I leave it plugged into the charger. The boot just showed the robot moving around a moment and then went to the Loading screen for about 30 seconds then brought up the home screen....
