Firmware for the SuperMax SM-9950 HD FTA satellite receiver, version V112 dated 11 February 2014, packed in a RAR archive of about 512 KB. FTA marks a free-to-air set-top box. Dumps like this are used to recover a receiver stuck on boot or a blank front display, either by USB or serial update or by writing the flash chip directly with a programmer. Check the hardware revision on the main board before flashing, since lookalike boxes often use different tuners or processors. Keep the existing firmware as a fallback.
