The rule is same version or the higher one within the Major, Minor closest to original, as detailed in the next linked thread.
The “11.0.11.1006_CON_LP_C_NPDM_PRD_RGN.bin” is part of a repository, from the following archive “CSME 11.0 Repository r55.rar” on this thread
EDIT: Work on full SPI image or ME_region image only
and there’s FIT tool versions variations 11.x, older ME FW images versions may work or not with latest FIT tool version avaiable 11.8.86.xxx. Older one should be 11.0.10.xxx
EDIT: Still, it could be image corruption… Care to share any dumps, if you want of course…
Fit11.0.10.1002.rar (4.9 MB)
EDIT: You may try this extracted/updated ME region, no guarantees…use UEFI tool (regular 0.25/0.28) to replace it or HEX editor.
Region_ME_ME_region.rgn.rar (1.4 MB)
That’s all from me, report back if you want, good luck.
EDIT: You should read this post… identical issue
