A major complaint from users is that after they get the firmware fixed , the device asks for a Google account they cannot remember (Factory Reset Protection - FRP).

Disable Windows Driver Signature Enforcement (Shift + Restart > Troubleshoot > Startup Settings). Install the SPD USB drivers. Without these, the PC will not detect your dead phone.
