These third-party tools generally function by sending modified ADB (Android Debug Bridge) and Fastboot commands to the phone while it is connected to a PC. They interact with the device’s bootloader partition, attempting to force the unlock bit to switch from "locked" to "unlocked." Because this process bypasses the official secure handshake between the device and the manufacturer's servers, it is technically a form of exploitation. While effective, it carries inherent risks that every user must understand before clicking the "download" button.
