Firmware archive for an iClass 9696X PVR satellite receiver, the variant without HDMI output according to the name. The RAR is about 1.06 MB and most likely holds a flash dump used to revive a unit stuck on boot or corrupted after a failed update. Before writing, confirm that your receiver really lacks the HDMI port, because HDMI and non-HDMI boards use different images. Read and save the existing chip contents with a programmer first, and check that the dump size matches the capacity of the flash memory fitted on the board.
