To initiate the process, the phone must be powered off, then connected to a PC while holding the Volume Down button.

This guide is intended for educational purposes. Unlocking a device you do not own may be illegal. Performing these steps will void your warranty, wipe all user data, and carries an inherent risk of bricking your device if not followed precisely. Proceed at your own risk.

While the process requires patience, driver installations, and the correct FTF file, it remains one of the most reliable DIY methods for bypassing forgotten screen locks and even old FRP protections on the Xperia XZ.
