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 authentica-
tion. Your phone can properly power on only after the
identity authentication passes.
