RAR archive of firmware for the Star-X C98 receiver, with a GigaDevice GD25Q32 flash chip named. The packed size of 2.63 MB says little about the files inside, so unpack it and check what it holds. A full dump for this 32 Mbit chip should be exactly 4 MB. If such an image is present, write it with an SPI programmer that supports GD25Q32 when the unit fails to boot. Back up the original chip first and confirm that the receiver really carries a GigaDevice memory.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
