Encrypted firmware for the Startrack SRT 9191 Gold receiver, version 1.09.15749 dated 22 February 2016, packed as a 2.29 MB RAR archive. The encrypt tag indicates a signed update image meant for installation through the receiver's own USB upgrade menu rather than for writing raw to the flash chip with a programmer. Several Startrack Gold models received the same build, but each file is tied to its own model, so use only the SRT 9191 package on this unit, and note the current version before updating.
