Bypassing the iCloud activation lock on a device that you do not is illegal in many jurisdictions. It is also a direct violation of Apple's terms of service. F3arRa1n should only be used on devices that you own and for which you have lost your own Apple ID credentials, or on devices you have explicit permission to repair.
