Samsung Galaxy Book Pro 360 firmware archive for model NP950QDB-KB1US, listed with board number BA41-02888C. It is a 6.55 MB RAR, so unpack it to see whether it holds a raw SPI dump or an update package; the name does not say. Samsung uses BA41-prefixed numbers for its laptop boards. When reflashing with a programmer, first read and keep a backup of the original chip, compare the image size to the flash capacity, and confirm the board number matches.
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 @biosarchive. Enginerys does not host this file.
