    anyone know how to downgrade B250 mining expert bios? ez flash 3 wont let me flash an older bios version
    I think you can downgrade your bios by using afuefix64 EFI shell . I won't give you any links here , but you can use google search how to flash bios using afuefix64 . I used it for downgrade 2 times and it worked fine for me.
    1) Put afuefix shell on your flash drive together with desired bios version . 2) boot from your flash drive and skip further EFI loading 3)type : fs6: (this can be different for you , to know your number you need to look what number will have Removable HardDisk in the list) 4)type : cd EFI 5) type : cd BOOT 6)type : ls
    Now you'l see a directory where afuefix64 shell and desired bios should be allocated . 7) type : Afuefix64 "name of your bios"BPNKXCLRCFG , wait until flashing is finished and enjoy your new "old" bios  Cool
