Factory Reset Protection (FRP) is a security feature introduced by Google on Android devices starting with version 5.1 (Lollipop). Its primary purpose is to protect your data and device in case it is lost or stolen. Once FRP is activated—typically after you set up a Google account on your device—it requires you to enter the previous Google account's username and password after a factory reset. This prevents a thief from simply wiping the device and using it as their own.
This method involves installing an APK directly on the locked device. While more convenient, it requires more caution due to the risk of malware. romfastcom frp verified
