6800xt Bricked

[RD1]

I was attempting to modify settings using Red Bios Editor on my 6800xt. Not sure what happened, but card no longer works. Device Manager recognizes the card is there but disables it. AMD autodetect tool recognizes the GPU and loads Adrenaline, but Adrenaline does not see GPU when Adrenaline is started-up. GPUZ- recognizes the card, but displays 0's where the various settings should be indicated. I've tried to reflash the bios. It goes through the flashing process successfully. However, when I open GPU-Z, it still does not indicate any bios changes have been made.

Pictures are shown below. I'm hoping someone has seen this before, there is a solution, and the GPU isn't bricked. But then again, I may have the proverbial paperweight.

Does More Power Tool work?
Load the bios file saved that's on the card.
Try deleting the SPPT and give it a restart.

Does it have dual BIOS? Try the other one if it has.
It's odd that even after reflashing you dont see a BIOS change. Maybe you are flashing same/wrong BIOS again?
Maybe try a stock BIOS from BIOS collection of TPU

I tried loading the bios file and then deleting the SPPT and restarting. MPT seems to work correctly. But when I restart, it takes me back to the same place. I'm going to try a different bios per other suggestion and see where that gets me.

My XFX has a switch next to the power connector. This should do the trick for you. At least to run the card and use it.

What happens when you enable the card in device manager?

In the device manager, I can deactivate and then reactivate the card. It will then show as being an active card. But once I try to use Adrenaline or restart the computer, it goes back to being disable in the device manager. I looked for a switch on my card. I'm running a Reference card, so no bios switch I can see.

No joy on the reflash attempt with another bios.

Red BIOS Editor doesn't support RDNA2 cards, so I'm confused how you managed to modify anything?

Plug the cable into the board and run the igp.
Uninstall the drivers for AMD gpu using DDU.

Use the iGPU to flash the original bios you pulled off the card. I certainly hope you saved an original copy!

If the flash is successful, power down, swap cable back to the card and try the driver installation again.

@RD1, the device id in the GPU-Z screenshot suggest you have a reference card.
If you have a reference card, you can use the orginal bios to reflash:

AMD RX 6800 XT VBIOS

16 GB GDDR6, 500 MHz GPU, 2000 MHz Memory

Well, I have followed all of the good advice here and reflashed the bios on the card using amdvbflash, in windows, command prompt, dos and also taking the card apart and using a ch341a programmer. I got the card to flash properly with every one of those tools. Seems there is something somewhere else in the card that got shorted out or damaged somehow, who knows? Anyhow, thanks for all of the advice and suggestions.

This just gets weirder. In my quest to fix my bricked gpu, I can now get the video will run through the gpu and allow me into the bios screen of the motherboard, but when I try to exit the bios screen and go to windows, the computer crashes.

Could be a corrupt driver. Did you remove the graphics card and run DDU?
