Help trying to repair bricked card

[Lakersfan]

Hello,
Something went wrong after I flashed using atom-15 and now it only boots to a black screen. I can only get an image on my screen if I remove the graphics card and use the onboard DVI port. How I can flash my card back to the original bios.rom?

Card: AMD RADEON HD 7450

Thanks!

Check if your motherboard's bios allows setting the integrated gpu as the primary one, so you can boot with video and flash the card back with its original bios.

Here, I used a motherboard with 2 pcie slots and 2 video cards, the working one in the first slot, the bricked one in the second.

Thank you! Just to be certain, now that I am able to boot using the internal gpu with the card in place, do I need to use atiflash to re-program the card back using the bios.rom that was created when I first flashed it?

If so, is this the command I'd use: atiflash -p 0 bios.rom

Looks right. I would use the same utility to reflash the original bios as you used to read it. There are newer atiflash GUI versions that can be used in windows now. I'm using amdvbflash_win_3.31.zip. Seems to work exactly the same as the older, commandline-based versions.

Having a plan to recover a bricked card is always a good idea either way

Thanks. Using the same utility I used to flash it initially, I did that and I'm still unable to get an image with the re-flashed graphics card. I'll try again

Looking in device manager, the Radeon card shows PCI bus 1, device 0, function 0 under properties. So with this, should the command be atiflash -p 1 bios.rom

I don't know. I would try to read from that slot first, mb? And compare the file you get out to what you expect it to be? Even if it's bricked, you should be able to read from it.

Or try the updated GUI version, where it makes things more obvious and you can see what you are doing

Thank you, that was helpful and I'm back up and running. Now off to more reading before I screw anything else up. lol
