Before you factory reset your Android GMS device, you should make sure that you remember your Google account credentials. If you do not remember them or if the person who set the credentials up left the company, you should delete the account before resetting the device.
Failing to do so will keep you locked out of the OS, and since FRP is active on Zebra devices, you would have to send the device for repair.
Procedure:
- Open Android Settings.
- Navigate to Accounts.
- Tap the existing Account.
- Remove Account.
- Confirm account removal.
