MS-4000 receiver firmware, version 1.09.20193 dated 2018-12-29, provided as a 3.80 MB .bin file. A dated build like this is handy for rolling back or recovering a receiver whose newer software misbehaves. The name does not identify the flash chip, so check the memory part on the board and whether this image is a USB upgrade file or a full dump for a programmer. Confirm the hardware matches the MS-4000 and save the original flash contents before writing anything to the device.
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 .bin file
A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
