Archive with Intel FIT version 9.6.0.1038, the Flash Image Tool from the ME 9.5/9.6 generation used with low-power 8-series and related mobile platforms. A technician loads the stock dump into FIT, reviews the descriptor and ME settings, and builds a new image containing a clean Management Engine region. Using a tool from a different ME branch than the firmware in the dump often results in errors, so confirm the version first. Read and store the original SPI contents before writing the rebuilt file back.
