Hello, I have a supersonic android 4.1, 7 inch tablet that has been locked due to too many pattern attempts. After that it asked to unlock via signing in to my google account but when i tried doing that it is rejecting it and there is no internet connection. I have also tried holding down the power button with the down volume button at the same time and visa verse but still nothing happened. I tried booting in safe mode as well but still no success. What should I do. I would really appreciate a prompt reply. Thank you.
