StarTrack 100 HD Galaxy firmware, version 1.7.08, PS Synaps build with one card reader and no CI slot, packaged as a 3.44 MB RAR archive under the Samsung brand tag. It is an older release of the same line and is useful for rolling back or recovering a box with corrupted software. Extract it with any RAR-capable tool, confirm that the hardware layout and model match, export the channel list beforehand and avoid power loss during programming to prevent a dead unit.
