Note: Remember the Google account your phone
last logged in to. During an untrusted factory
settings restoration or microSD card–based update,
Google's anti-theft mechanism requires you to
enter the Google account your phone last logged
in to on the startup navigation screen for identity
authentication. Your phone can properly power on
only after the identity authentication passes.
