The Google account after a reset

Factory reset protection asks for the Google account that was on the phone. That is not a SIM lock.

1. 01

   After a reset, Android can ask for the last Google account that was signed in. Have that email and password, or the account recovery that Google itself offers.

2. 02

   Removing the account before the reset, in Settings → Passwords & accounts, is the clean path when you still have the phone unlocked.

3. 03

   A carrier unlock does not know your Google password. USB debugging does not remove the account.

4. 04

   If you cannot sign in because the account is not yours, stop. Do not look for a tool that skips the check.

Official carrier and settings procedures only. This is not a bypass, IMEI, or stolen-phone service.
