RAR archive of firmware for a StarTrack Platinum II satellite receiver, with the brand and model spelled loosely in the name and no version or date given. At 6.91 MB it is larger than the other Platinum II packages, so it may bundle several builds, a loader tool or a full flash dump. Open it with WinRAR or 7-Zip and read any included notes. Before flashing, confirm the main board and tuner match your unit, and save the current firmware so a failed update can be reversed through the serial port or a programmer.
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.
