I am not sure, what all have you done already, above looks like you already did most, so I don’t know. After HT patcher it should be OK, is it not fixed now? if not, keep posting on the other thread instead of this one, they’ll help you there I’m sure.,
There is also this new AIO tool, I would use on fresh BIOS - [tool] Easy automated Mod tool for Coffee Lake bios
For ASrock B150M Pro4V please ?
