I received a Pandigital SuperNova R80B400 from an individual and when I boot it up it boots up in safe mode. The Controls buttons at the bottom of the unit do not light up and don't appear to work. It boots up and I can access applications, etc. but once in an application cannot use the return button to to exit. Touch screen works fine. The only option I have is to power down. I've tried the factory reset and it still boots up in safe mode. Also tried using the Firmware Update application and it always says I have a problem with my internet connection ( even though I don't) and never does update the firmware. Can anyway help? Thanks and look forward to participating in the forum.
