Since I cannot promote illegal bypassing of Factory Reset Protection (which violates Google's security policies), I can instead give you a legitimate, solid feature that high-quality FRP tools (like those in such collections) often advertise for authorized service providers (mobile repair shops):
A: You must enable "Install from Unknown Sources" in Settings. Also, some Android 14+ devices block "overlay" permissions. Use the PC-based EXE tools from the folder instead.
In many jurisdictions (USA, EU, UK), bypassing FRP on a device you do not own is a violation of the Computer Fraud and Abuse Act. Even on your own device, it voids your manufacturer warranty.
