To unlock or relock the bootloader on most Android devices, you must use a computer with ADB and Fastboot tools installed. This process through a factory reset and may void your warranty. Prerequisites

The "relocking" part of the status was what bothered her. Usually, once you unlock a bootloader, "relocking" it is a final step to restore security. But this device was trapped in a loop. It was trying to relock itself to hide what had been installed, but the 167z firmware —a high-security experimental build—was fighting back. It refused to "verify" the new, unauthroized software.

This is where the "verified" part of your query becomes critical. Many users want to relock their bootloader to restore the device to stock for warranty purposes or to sell it.

Relocking the bootloader is often done to restore some, but not all, functionality (such as SafetyNet/Play Integrity passes in certain scenarios, though Knox remains tripped).

SE 167Z (Stock firmware version 3.2.1 and above) Status: ✅ Confirmed working

Unlocking the bootloader is designed to perform a factory reset for security reasons. This prevents an attacker with physical access to a lost device from simply unlocking the bootloader to bypass the lock screen and access your data. The unlocking process will wipe all user data, including apps, photos, files, and settings. Before you begin, ensure you have a complete backup of all important information from your device.

To anyone else, it was a glitch. To Elara, it was a crime scene.
