Understanding the Lock
FRP (Factory Reset Protection) is a security feature on Android devices. If a customer hard resets their Nokia C31 without removing the Google account first, the phone locks down on reboot.
For technicians, removing this lock is a daily task. On Unisoc devices like the C31, standard bypass methods often fail on new security patches. TSM Tool Pro communicates directly with the device’s diagnostic port to reset this partition securely.

“A customer brought in a C31 stuck on the Google lock screen after a hard reset. The September 2024 patch level meant manual bypass was impossible. Connected it to TSM Pro in Diag mode, selected the model, and it was done in 20 seconds. Easy money and a happy customer.”
