NOTE: Create a Google account before setting an unlock pattern and
remember the Backup PIN you created when creating your pattern lock.
Caution! If you haven't created a Google account on the phone and you
forgot your PIN, Password, and the backup PIN, you need to perform a
hard reset. But if you perform a hard reset, all user applications and user
data will be deleted. Please remember to back up any important data before
performing a hard reset.
