I would like to reset the ME region to the same version and settings of the stock bios (I previously updated it with FWUpd); reflashing the bios (even using Asus flashback) doesn’t overwrite the ME firmware.
I tried extracting the ME region with UEFITool and reflashing with Flash Programming tool, but I get Error 451: The host CPU does not have write access to the target flash area.
Dumping the region works.
How to unlock it for flashing?
Thanks!
