Note: Remember the Google account your device
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 device last logged in to on the startup
navigation screen for identity authentication. Your
device can properly power on only after the identity
authentication passes.
