Version 11.6.10.1196 of Intel's Flash Image Tool, packaged as a 4.97 MB RAR. An earlier 11.6 build, it opens a full SPI image, displays the flash descriptor and the ME, BIOS and other regions, and builds a new image once ME configuration is adjusted or clean firmware is inserted. This is a standard tool for restoring a healthy ME region on boards with Management Engine faults. Match it to 11.6 ME firmware in the target image, verify the output fits the flash chip, and always back up before writing.
