40-ms801a-mac2hg Firmware -
Most MS801 boards have a dedicated USB port labeled "SERVICE" or "USB 5V 1A" . The process is:
Warning: Do not interrupt power during flashing. A corrupted bootloader requires an SPI programmer (e.g., CH341A) to recover.
There are two primary ways to install firmware on MS801 series boards: the USB Update (Service Mode) method and the Programmer (ISP) method.
Before attempting any update, you must confirm your hardware matches the firmware.
Remember: Always ground yourself before handling the mainboard. One electrostatic discharge can destroy the NAND flash containing what little firmware is left on the chip.
