Thanks for your fast reply 
Yes sounds like the only solution left. However, I'm unsure as to which bios is the original one. Should I start with the 339w version from 2022 in the respitory? As I did try to flash one of the versions from 2023 (they are both uploaded the same time and date), both 400w limit but diffrent hash id. Seeing as one of those 400w bioses bricked my card maybe I should steer clear of the other one and go for the 339w version and then use the Asrock update utility?
