BIOS for MSI RX 470 Armor 4G Hynix and Samsung memory

I have seriously f***ed up some of my graphics adapters.
Now I am looking for the original BIOS ROM for these cards:

MSI RX 470 Armor 4G with Hynix memory
MSI RX 470 Armor 4G with Samsung memory

Please help if you can and make a ROM dump with ATiflash.

Thanks all
