A flashed GPU

[NNzt]

Is there a way to undo a flash in a gpu?

To fix a GPU which has been bricked by a failed GPU BIOS flash, see this: http://www.overclock.net/t/593427/how-to-unbrick-your-bricked-graphics-card-fix-a-failed-bios-flash

You flash it back to the stock BIOS.

There are two issues:
1. IF the graphic card BIOS is messed up enough then you cannot re-flash the BIOS. This is like a non-dual bios motherboard, and is the reason for dual bios motherboard. If this is true then card is dead.
2. If the graphic card BIOS is working well enough to do a flash, but not well enough to run the display then you can use either the integrated graphics in your CPU or a second video card (not in SLI) to drive your monitor so you can see what you are doing when you re-flash the video card. This is reasonably common.

IF you have integrated graphics, then pull the old (bricked card), move the video cable to the MB's video out, boot to the BIOS, and set the bios to forced integrated video (this is a configuration used for example when the video card is for CUDA not display).

If you do not have integrated graphics then you need two video cards in the PC, and you will need to have the bios use the working one for video. You CANNOT hot plug PCIe in a PC, so do *not* get the pc running and then add the second card.

Once you have the bricked card installed with video working, do a normal driver load. Driver load forces a video bios update.
