Specifically this command below forced the downgrade from 3006+ to 2002

afudos TUF_MK2_BIOS_2002.CAP /p /b /n /k /x

Thanks for your info.
I am looking forward to downgrade my x299 from 3501 to 2002 too.
Your command :
afudos TUF_MK2_BIOS_2002.CAP /p /b /n /k /x

1/ is it the change inside autoexec.bat file ?
2/ file should be .CAP instead of ROM ?

Thanks for your help
