Hi, I'm trying to boot into recovery mode but haven't had any success with the various combinations of volume button and power. I have a Mid Android Tablet PC. I keep getting the android symbol with exclaimation mark on top. I don't know how to get to the recovery menu. Could you please help me? What does the android with exclaimation mark on top mean anyway? I need HELP and would appreciate any that I can get from anyone. I'm not sure whether it's a battery issue (because I can't even access that battery symbol) or just needs to be hard factory reset. Thanks.
