The process involves placing a "bin" file—typically named MstarUpgrade.bin—onto a FAT32-formatted drive. The technician must then trigger the bootloader, often by holding the physical power button while plugging in the AC cord. This method bypasses the corrupted or outdated OS to write the new firmware directly to the SPI Flash or eMMC storage.
