Flashing Bios to Correct Card

[GreenDayUnicorn]

I am currently in the process of using ATIFlash to unbrick a XFX Radeon RX 570 GPU. Though I have a working MSI ARMOR OC 4GV RX570 being used as well. They are both plugged and powered. The bricked card also has no display coming through it, hence why I have another plugged in with it. I do not have any discrete or integrated graphics. Though I would like to fix the XFX, I really don't want any risk of accidentally screwing up my good card. I've already got the BIOS rom file downloaded. I just need a walkthrough to flash it. This is what is showing up on ATIFlash when I start it up:

The cards being used:
Main
Bricked

Motherboard: Link

I have my main card plugged into the PCIe X16 4.0 slot, and the Bricked in the PCIe X16 3.0 slot. If either of that helps.
