How do i unlock a google lock on a Galaxt S 7+

[Android Central Question]

My s7+ was stolen for about a week. I logged into find my device, locked and erased it so that no one could get into it, then I found it. Now it wont let me in. I've entered every email that was associated with it, and it still asks for an account that was associated with the initial setup! I'm stumped. Please help. Thank you

Have you tried reflashing the ROM?
