After resetting my RCA tablet, I cant login. Je te the message I have been getting "this device was reset. To continue, sign in with a Google account that was previously synced on this device". But I am using the same e-mail but keep getting the same error.
The only fix for this is to use the exact same account that was originally used. If the account you were using prior to the reset was not the original account on the device, that can give you this problem.
We would not be able to fix that. You can only do so with the original info.
