Software release V112 for the SR-T30 receiver, dated 10 September 2019. The 4.64 MB zip archive should hold the firmware image for this unit; extract it to see whether it is a USB update file or a raw flash dump. Such images help fix receivers stuck in boot loops, showing no signal menu or bricked by an interrupted update. When programming the SPI chip directly, read and keep the original data first, and check that model and main board on the device match the file before writing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @tamirkaran_chanel. Enginerys does not host this file.
How to open a .zip file
Compressed archive that every operating system opens without extra software.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
