Did someone perhaps have access to your tablet to change the pin? Or did you change the pin when you first got it? If you can't get in, my understanding is you have to do a hard reset.
I've tried by pressing the power button and the down volume button at the
same time, it basically restarted and went back to that screen asking for
the pin. It is my daughter's tablet so she probably changed it and doesn't
remember. I've tried everything to get into the tablet. So frustrating.
Ok, it seems to be resetting but it is in a different language....maybe
Chinese or Japanese. I have no clue.
