Flashing custom bios with afudos on Asus ami motherboard

[SamsungASUS]

Hello, I currently want to flash a custom bios unlocked with amibcp with either afudos or afuwin on my Asus b450m-a/csm, but when I flash with afudos, it either completes and nothing changes in the bios, or it fails with "problem with allocating memory." When I flash with afuwin, it either fails with something like "file is not a secure file" or "problem allocating memory." I tried to flash the bios for days with no luck. If you all could help me out with this issue, I'd gladly appreciate all you guys' help.
