Hi there and welcome
Can you tell me the make and model of the Tablet? And is it the screen lock you cannot get past?
I'm sorry about the issue. I'm another tech; I can help you with this. I do live online support. Can I provide you written instructions here?
What's the model of your tablet?
Is it okay to reset the tablet fresh, so you can re-set it up fresh, like brand-new, so you can set it up with a new Google / gmail account and password ***** want?
