Second variant of a firmware package for the StarTrack 2017 HD receiver, packed in RAR and slightly smaller than the similarly named archive, so its contents likely differ. The name does not state a version or date. Compare both archives before choosing which to load, as receivers sold under one name may use different main boards. Flash via the receiver update menu or a programmer on the SPI chip, and read out the original firmware beforehand to allow recovery if the box fails to start.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @tvsoftwareworld. Enginerys does not host this file.
