AFUDOS - bad checksum

[creysson]

Hello there,

I modified my BIOS on MSI GE62VR but I cannot flash it. Tried even flash the same copy as I dumped.
I'm still getting the error in Bios Checksum verification.

I notice every new dump produces the same bios with a different MD5 checksum, is it right?

Thanks for any help.

I managed to dump and to flash the BIOS with INTEL FPT.
After modified with AMIBCP for aptio V and flash, the menus remains locked.
 
I believe it's hard coded.
Meanwhile I extracted setup.ffs but I don't know which HEX sequence I should look for.
 
Any directions?
