Don’t use AFU as it tends to dump chip contents without caring if some regions are locked, and thus inaccessible, leading to incomplete SPI images. Don’t use UBBT as it’s ancient and doesn’t work with anything modern.
The only proper dump is the one from the Raspberry, the other two are either incomplete or corrupt. Download the latest BIOS from ASUS and work on that. You have a desktop motherboard, there is no need to use your dump.
