If your having problem like this I suggest that you perform a hard reset. To hard reset just simply follow this step.
And remember reseting can delete your all access data specialy passwords and code.
To hard reset:
1. Turn off the whole system.
2.Hold together buttons: Power + Volume Down. In several second until logo appear on the screen.
3. Release the buttons. And without asking and without notice System will automaticaly doing a reset.
If this will not succesfull, try to create google account on PC. Then remember all information you've made, the email and password. You said system asking you to sign in to google. Use all information you've got to sign in.
Note: The google method is not working on other tablet, but most of it solve the problem. Then you should go to area where you have an a access of wifi, place where can you connect a wifi. Internet connection is realy realy needed.
Hope it will help.
