Most MTK exploits rely on interrupting the bootrom during the first few milliseconds of power-on. In "hot" mode, the device is already running the preloader or has already handed off to the main bootloader (LK - Little Kernel). The USB enumeration changes, and the BROM's debug interface is locked. The MTK-SU tool expects a specific handshake (e.g., sending a specific byte sequence like 0xA0 0x0A ) that only works in BROM mode. In "hot" mode, the device responds with error codes like STATUS_BROM_CMD_FAIL or simply times out.
