Firmware for the SuperMax SM-9400 USPI satellite receiver, version V1.2.43 dated 4 May 2014 per the name. The 768 KB rar archive needs extracting before use and typically holds the loader or upgrade file for the set-top box. Technicians load such files over USB or RS-232 with the maker's upgrade tool, or write them directly to the flash chip on a dead receiver. Confirm the exact model and main board match, because firmware for a similar-looking box can leave it stuck on boot, and back up the existing flash first.
