ZIP archive of 3.50 MB carrying firmware v1.39 for the Openbox S3 Micro satellite receiver. A file like this serves to reinstall the system software on a box that freezes, reboots repeatedly or lost its menu after a bad update. Load it via USB or the manufacturer loader over RS-232 as appropriate, after confirming that the unit is the S3 Micro and not the larger S3 model. Expect settings to be reset, so export the channel list first, and never cut power while the image is being programmed.
