Question How do I re-flash the VBIOS of my Bricked RX 5700?

[Cybronator]

I was attempting to flash the vbios of my msi rx 5700 oc mech gt edition (because of the performance improvement) but due to a mishap, the vbios was erased completely and the card does not have a dual bios or a batch file recovery in place. I was frantically searching the web for a solution and while there are some seemingly tangible solutions, they are very confusing and at times quite vague. I do however have the equipment needed to get a vbios back on my card (i have a backup amd gpu and a working computer with multiple pcie slots (no integrated graphics) and power support, I also have a usb stick.) At the moment, my rx 5700 is not displaying anything but the fans are still spinning.

I am thinking of creating a batch file which I can use to flash the bios (blind) by just using keys to re flash the vbios but this is quite complicated and I need guidance on how to do that. I am also thinking of plugging my backup and rx 5700 cards into my motherboard and prepping the flash and then switching graphics card. However, I am worried that I may then flash my backup amd card with the vbios of the rx 5700 which would of course be very bad and would the bricked card come up in the bios? A third possibility is creating a dos usb stick but how am I supposed to flash from the usb stick (in the bios) if my gpu is not giving me video output in the first place?

I also have another (separate) computer with integrated graphics but with a locked bios. I could theoretically still flash the vbios from the desktop (on integrated graphics) but will the bios pick up the bricked card? (this computer is not at my current location so I have not tried this yet.)

I need some advice on what to do and how to reinstall a vbios/gpu bios on my rx 5700 so I would be very greateful if someone could run me through what to do, especially because if I make another mistake I won't get another oppertunity.

Thanks

You can try flashing it as a second card with atiflash.
Similar bios is not enough - all markers are different by color and taste, you need a BIOS from exact same hardware. Tye same model may have different GPU/board revisions, different memory chips with different timings etc... Exact same card BIOS.

If you can’t get the card flashed with atiflash, and can’t RMA it, you can try flashing it externaly.

Thanks for the reply,

I will attempt to flash it with the backup gpu alongside it. I guess that the main factor deciding success will be if i can get my bios to detect the gpu as a secondary vision device.

This seems like the most specific bios I can find so it should work. https://www.techpowerup.com/vgabios/213874/msi-rx5700-8192-190805

We will see if this works.
