Huawei Y5 Quick Start Manual page 113

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.
Model: HUAWEI Y560-L01
