Amd 5700xt bricked dual bios

[vlt]

I recently bought a used 5700xt with with dual bios. I flashed a modded bios on that and bricked it. I thought no worries and switch to the other one and put the original back on the first one but it was already dead. So now I have a card with 2 bricked bios that wont post., I have another card that boots and added the bricked one but no post, same on both large pci slots, also triesd another motherboard. So if anyone has the the skill and tools to fix contact me I have the original bios
