RAR archive of roughly 2.98 MB for the F18-HD Super Plus satellite receiver, tagged with the index number 73690. No firmware version or date is stated in the name, so the archive should be opened and its files examined before flashing.

Confirm that the board and flash chip match the F18-HD Super Plus, and always save the original memory contents so the unit can be returned to its starting state.
