Firmware for the Star-X C98 receiver in a ZIP archive, version V1.09.17415 dated 30 November 2016, which makes it newer than other C98 builds. At 2.80 MB it is most likely an upgrade file rather than a full SPI dump. Extract it and apply it through the receiver's update procedure, keeping the power stable during the process. Confirm the C98 model first. A unit that no longer boots instead needs a full chip image written with a programmer after the original memory has been read.
