Factory Reset Protection (FRP) is a security feature introduced in Android 5.1 to prevent unauthorized device access after a factory reset. Despite its intent, various tools—including QSF (Qualcomm Secure Flash)—have been used to bypass FRP on Samsung devices with Qualcomm chipsets. This paper examines the technical mechanisms behind such bypasses, evaluates their effectiveness, and discusses the security implications.
The QSF Tool was designed specifically for Samsung devices that use . While compatibility can vary, the tool has been reported to work successfully on models like the Samsung Galaxy A01, A02s, A11, A70, and M11.

Many standard Samsung FRP removal utilities use a software-based exploit rather than low-level hardware flashing.
