The software will detect the 167z hardware configuration automatically. Follow the on-screen prompt to submit your unlock request, triggering the tool to push the cryptographic payload. Method B: The Manual Fastboot Command Line
The cryptographic signature matches the public key embedded in the hardware fuses.
Use a computer with ADB/Fastboot installed and run: adb reboot bootloader Alternatively, use hardware buttons (commonly Volume Down + Power ) while the device is off.

Throughout the process, Alex kept a close eye on their device's firmware and bootloader versions. They verified that the bootloader was indeed relocked and that the firmware version was still G950FXXU1ZAP3 (167Z). The device was now in a stable and secure state, with the bootloader locked and the warranty intact.
To fully re-verify the se environment parameters and lock the secondary system partitions, execute: fastboot flashing lock_critical Use code with caution. Step 4: Finalize and Reboot
