Intel Flash Image Tool release 14.0.60.1790, delivered in a 6.50 MB RAR. As a later build in the 14.0 line, it can handle newer ME firmware of that branch. FIT lets a technician decompose a dump, edit the descriptor and straps, swap in a clean ME region and output a complete image to program into the SPI chip. It is a common step in fixing ME-related boot or power problems. Confirm the firmware version matches, keep a backup of the original chip and check that the output size fits.
