The client sends a specific "payload" (often referred to as Kamakiri) that exploits a vulnerability in the BROM's USB stack.

The tool operates by targeting two specific modes inherent to MediaTek chips: and Boot ROM (BROM) Mode .

Revives "bricked" devices that are otherwise unresponsive.

Disables "Serial Link Authentication" and "Download Agent (DA) Authentication," allowing unauthorized firmware to be flashed.

Once the exploit is active, the tool forces the chip to skip its standard security checks. This allows the client to interact with the device's flash memory without needing authorized credentials from the manufacturer (e.g., Xiaomi or Samsung).

When a device is powered off and connected to a PC while specific hardware buttons (like Volume Up or Down) are held, it enters BROM mode.

Reads, writes, and erases individual partitions (e.g., boot, system, recovery, user data).

Extracts BootROM and Preloader information for forensic or development purposes. How the Exploit Works
