Android Factory Reset After a factory reset on my Note 5 the first step after selecting language Google requires is the previous email account entry, I've entered my gmail account and password 10 times and it keeps telling me to use the original. It is the original. Except for an updated password. It is an endless loop; how do you get out of it?
If you are completely positive that that email is correct, try these things:


Resetting the password to the original (if you know it).
Make sure you're using a Google account (Or Gmail).
Contacting your service provider's help line or contact support.
Contact Samsung here. 


Good Luck. I would recommend contacting Samsung BEFORE your service provider.
