ZIP archive of the Star-X 99 USB encrypted firmware, version V1.09.14618 with a build date of 17 August 2015. The name marks it as the USB edition of the 99 model. Being encrypted and only 2.63 MB, it is an upgrade package rather than a complete flash image. Apply it through the receiver's update function after confirming the model and edition. Firmware for the C99 or other variants is not interchangeable, and a receiver that will not boot needs a programmer and a full chip dump instead.
