Semi-Bricked AMD Radeon RX 570 4GB

So I recently got a new PC, and after I set it up my GPU was not working. I tried installing Radeon Drivers but it did not work. When I checked device manager, it said the GPU said error code 43, the device had an error so it could not be started (now I know that it was because of a bad but still usable vbios). So I tried flashing a custom vbios. It worked and said I need to restart. But when I restarted, my PC turned on but my displays were black. I did my research on what to do and I came across the fact that most gpu's have 2 bios's, 1 for recovery. so switched to the Recovery bios and everything worked. Even the error 43 code was gone (I realized that I could have saved this bios and then flash it on the primary bios, but now I can't do that). So now I have the problem of getting my Primary bios back up and running. I need to find a way to flash the bios that I saved from the second bios to the primary bios, which I can't really do because all I get it a black screen. And no I do not have integrated graphics so booting up using that won't work.

So why does the 2nd bios that worked no longer not work? also post pics of white stickers on the GPU and GPU-Z if you can

Also you can start with the "working" bios and flip it whilst inWindows to flash the "non-working" bios

Sorry my first post was really sloppy. I'm going to refer to the Primary bios, which stopped working, as bios 1 and the recovery bios, which still works, as bios 2. Bios 1 stopped working because I accidentally flashed a wrong vbios. Bios 2 is working properly. I can't use the PC right now, but I'll send one as soon as I can.

And what do you mean by starting with the working bios then flipping it?

Thank you so much!

start with recovery bios, in windows switch to bios 1 and flash a good working bios to it

So its that easy? I thought I would have to do a blind recovery or something. I will try it and let you know if it works. Thanks a lot.

lmao I'm sorry I didn't get a chance to try it, because I lied, it's not my computer, it's my friends computer. might take a week or a month. I'm also considering using freeDOS's autoexec.bat to fix it too. maybe windows 98 idk.
