Older StarTrack Platinum II receiver firmware, version V1.25B2, with a 0117 date code and packed as a 3.81 MB RAR. It is an earlier release than the 1.27 builds and suits rolling back when a newer version misbehaves or does not suit a particular hardware batch. Open it with WinRAR or 7-Zip and flash it with the serial upgrade tool or an SPI programmer. Save the current flash contents first, and check that the main board matches, because builds for similar-looking boxes are not always interchangeable.
