The combination is a specific failure signature for Alcor Micro controllers in a bootloader or thermal fault state . Recovery requires identifying whether the cause is thermal, power-related, or firmware corruption. If the IC remains cool but still shows FA00, attempt firmware reflash. If hot, address cooling and power first to prevent permanent damage.

Download the AlcorMP archive, extract it to a folder, and run the executable (typically named AlcorMP.exe ) as an administrator. The tool will scan for a compatible USB device.
