Update package for the SR-7080 satellite receiver, Jordan1 build, firmware V104 dated 17 November 2021, supplied as a 5.60 MB zip. A Jordan 2.0 build with the same version also exists, so identify the correct variant first. Inside you should find the firmware image for loading by USB or programmer. Compare the board and hardware against the unit and read out the existing flash with a programmer, keeping the backup in case the receiver does not start after the update.
