RAR archive with firmware for the Galaxy Innovations GI Slim 2 Plus satellite receiver, going by the name. No version or date is given, so check the contents before use. Such files are used to update the receiver or recover it after a failed upgrade, typically through USB or by programming the flash memory directly. Make sure the model, including the Plus variant, matches the target box, and keep a read of the existing flash so the original software can be restored if needed.
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.
