Intel FIT version 12.0.68.1606 in a RAR archive, noticeably larger than its neighbours at 13.3 MB, so it may bundle extra files beyond the tool itself; the name does not list them. The Flash Image Tool decomposes an SPI image into its regions, lets you adjust Management Engine parameters and outputs a rebuilt image. Board repairers rely on it to clean or replace a damaged ME region. Pick a FIT version that matches the ME firmware major and minor numbers, verify the result fits the flash chip size, and back up the original contents.
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 @mfittool. Enginerys does not host this file.
