I have a Digimate T909S tablet which has been running extremely slowly, so I have attempted to reset it back to factory condition. Now, when switching it on, all I can get is the Digimate logo which continuously circles, and nothing else. I have tried leaving the machine switched on for a couple of hours but it still will not move on from the digimate logo. Can anyone suggest a way of resolving this and getting the tablet up and running again? Would be very grateful for any advice or suggestions.
