RAR archive of about 1.13 MB for the SuperBOX Mini S200 MX PVR satellite receiver, most likely a firmware or dump set for this PVR-capable model. The name gives no version or date, so open the archive and inspect its contents before use. Such files serve to restore a receiver that fails to boot or to reload the software after flash corruption. Compare the board markings and the flash chip type with the source of the image, and keep a backup of the existing memory content before programming anything.
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.
