RAR archive (4.85 MB) with Intel Flash Image Tool 11.0.0.1202 from the version 11 ME System Tools. The 11.x branch is associated with the Skylake and Kaby Lake era platforms. FIT reads a complete SPI dump, separates descriptor, ME and BIOS regions, and rebuilds the image with a clean or updated ME firmware and adjusted settings. Repair shops use it to fix ME corruption before reflashing the chip with a programmer. Confirm the ME version in the dump matches this tool's branch and keep an untouched copy of the original read.
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.
