In 2015, Google introduced Factory Reset Protection (FRP) to deter phone theft, making a device useless unless you know the original owner's Google credentials.
The name refers to a specialized utility tool often found in the independent developer and mobile repair communities. These "all-in-one" tools are typically created by individual developers (like the namesake "Shariff") to help users bypass Factory Reset Protection (FRP), flash firmware, or unlock features on Samsung devices without expensive professional equipment.
Because these tools are distributed on unofficial forums and file-sharing sites, they are often used as "trojan horses" for malware.
