Modding Asrock X470 BIOS, Secure Flash error

Alright, I’m doing this differently as for whatever reason I’m not getting the same results as you. I’ve located what I think is the AMI Aptio Capsule (GUID 5A88641B-BBB9-4AA6-80F7-498AE407C31F) and simply removed it, rebuilt the image and saved it. The file opens perfectly fine with AMIBCP and everything looks to be in tact but I don’t know if I can outright yank out what appears to be the secure flash check and leave it out. Just to make sure I’m not missing anything what do you mean when you say to let UBU scan? Is that something it does automatically when the file is opened?

Thanks , I know I’m being really dense here first time I’ve needed to remove protection in this way.

EDIT: Ok I realise what I’ve been doing wrong (I think) I’ve been doing everything with UEFITool when I just needed to run UBU.bat.
