This guide uses an official downgrade firmware package — Jackman-L22 9.1.0.220 (C636E1R4P1T8) running on Android 9.0 (EMUI 9.1.0) — installed via SD card to reset the FRP state on your device.

What Is FRP (Factory Reset Protection)?

Factory Reset Protection is a built-in Android security feature introduced in Android 5.0 (Lollipop) and present in all later versions including Marshmallow, Nougat, Oreo, and Pie.

FRP activates automatically when a Google Account is set up on the device. After a factory or hard reset, Android requires the original Google Account credentials to be entered before the device can be used again — preventing unauthorized access if a phone is lost or stolen.

If you remember your Google Account credentials, the easiest fix is simply signing in on the verification screen. If you’re genuinely locked out of your own device, the downgrade method below is the recommended solution.
