Version 11.0.0.1180 of the Intel Flash Image Tool, archived as a 4.85 MB RAR. Part of the ME System Tools for the 11.x Management Engine, FIT is used to open a BIOS region dump or full SPI image, review flash descriptor settings and ME parameters, and generate a rebuilt image containing a clean ME region. That output is then programmed into the SPI chip. A mismatch between the tool version and the ME firmware generation can produce errors or a non-booting board, so verify the version and preserve the original dump.
