Hi, I have this MB that someone else tried to repair.
The MB had clear indications that the SPI ROM was removed.

I have a dump file, but i don´t know if it is the original one or not.

Can you help me clean ME Region? I tried to do it but failed with 16.0 FIT.
Also I didn't found a RGN region only EXTRACTED and I don't know if those would work.
