Assuming integrity data match on files provided vs new dump after flashed…
Well, sorry but both images have different ME fw versions and cleaned, the only part i didn’t touch was NVRAM volumes in bios region. Didn’t saw abnormal data in bios region reaming volumes. You can try to merge them from Intel bios file 042/093.
Good luck.
EDIT: Since you got nothing to lose here…give it a try with lfb6 file provided to user here, just to check if behavior is the same…
