Android has an anti-theft measure called Factory Reset Protection (FRP). It means that, even after you wipe an Android phone, you need the last Google account login to set it up again. You'll need to disable FRP properly. Go to Settings > Security > Screen Lock, and set it to None.

The next step is to remove your Google account, but we recommend removing all of your accounts at the same time. You can do this in Settings by tapping Accounts. Select each one in turn and tap Remove Account.
