Firmware archive for the Microsoft Surface Pro 3 with board part number X896569-001, packed as an 11.8 MB RAR. The name gives no version or status, so open the archive to see whether it holds a single image or several files, and check each against the flash chip on the board. Technicians use such dumps to reprogram the SPI chip with a hardware programmer after corruption or failed updates. Back up the original chip first, since it carries serial and calibration data unique to that tablet.
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.
