Startrack SRT 9292 Gold software in encrypted form, version 1.09.15749 built on 22 February 2016, delivered as a 2.29 MB RAR archive. An encrypted image like this is applied from a USB drive through the receiver menu, not programmed directly into the flash chip. The same release exists for other Gold models, but cross-flashing between models can disable the box. Confirm the SRT 9292 label before installing, keep the unit powered throughout, and note the current version in case a rollback is needed.
