Present in Vietnam for a considerable time, recent Sony Xperia models offer diverse designs with uncertain origins, raising concerns about potential risks such as lost DRM KEY and the impact of bootloader unlocking.

Unlocking the Secrets of DRM KEY on Sony Xperia Devices
DRM KEY is a unique code from Sony designed to verify the origin of your device. This code activates proprietary features like Bravia Engine/X-Reality/Super vivid, BIONZ, Download Music Info, and more.
DRM KEY resides in the crucial Trim Area Partition. When unlocking the bootloader, it's imperative to back up this partition. Failure to understand this can lead to permanent loss of the DRM KEY. Even searching online for relocking the bootloader won't help recover the DRM KEY.
