Unlike the iPhone 6s or 7 (which run iOS 15), the iPhone 5s on iOS 12.5.7 has a narrow set of vulnerabilities that make bypassing theoretically easier.

Before attempting any bypass, it is vital to understand what you are up against. Activation Lock is a feature of "Find My iPhone." When a user enables Find My iPhone, their Apple ID is stored on Apple’s activation servers and linked to the device.
