This is crucial. For many devices, this involves shutting down the phone and holding both Volume Up and Volume Down buttons while connecting to the PC, or using the command adb reboot edl .

On vulnerable devices running software builds older than 1662, the primary bootloader loader (often the Little Kernel or LK) failed to adequately sanitize commands forwarded to the SE config partition ( seccfg ). By utilizing specific low-level hardware communication protocols (such as MediaTek's MTKClient or Unisoc exploit scripts), attackers and power users could force-write an UNLOCKED status directly into memory. This bypassed the requirement for an official manufacturer unlock code or token. The Relocking Risk

To understand the complexity of relocking, one must first understand the bootloader's role. The bootloader is the first piece of code that runs when a device is powered on. Its primary directive is to verify the integrity of the operating system it is about to load. Manufacturers like Sony implement a secure boot chain, often utilizing technologies like TrustZone, to ensure that only authorized, signed software runs on the device.
