How To: Unbrick Your Bricked Graphics Card/Fix a Failed BIOS Flash - Page 12

I owe you a beer! It took me two days and a ton of navigating but I fixed both bricked 6950's! Thank god I had some old dusty first gen PCI-e card in storage. seriously though there are many people who owe you a thanks!

I've gotten all the way up to step 15. When I enter "atiflash -i" to find my adapter number, I get "Bad command or file name". What am I doing wrong?

I was using ATIWinflash instead of ATIFlash.

I get error OFL01, I've reseated my card a couple of times, still no good.

Try this switch;

 

atiflash -unlockrom 0

 

 

Edit:

 

Do you have bios.rom in that folder? It said file not found.

 

C:\Folder > bios.rom

 

Your file has no extension. Atiflash will not be able to read "bios". It has to be bios.rom or bios.bin.

Yeah, bios.ROM was in the same folder, I don't know why I'm getting "file not found".

Everything's working great now! Thanks so much for all the help you guys gave me, both Core2uu and Ken1649.

I went through the whole thread. I am having a similar issue as many here. I have an ATI 5850 card. Last week, ATI prompted me to updrade to CCC 12.2. The update sent my card into a tailspin where it would crash while running video and any game. I had had some issues with the GSOD rarely with some simple games, so I took this opportunity to just try and fix everything. I found a modified .rom from someone having similar troubles and decided to try flashing...whoops! Uninstalled drivers and flashed from DOS loading USB. Rebooted with lovely black screen and computer not booting up. So I switched to the IGP and booted up with atiflash in DOS off a USB, but I get the "Adapter not found" message on atiflash -i. I have now disassembled the card and was prepared to do the pin 1->8 bridge, but my chip labels are quite a bit different than what has been listed.

The 8 pin chips are as follows:
Backside
-up7701u8 agp072(which i believe handles the voltage stepping)
-a chip with a bright green sticker on it that says TV252 H5102 (took sticker off and chip is blank. It also has a U11 label above it)
Frontside
-another up7701u8 chip
-one on the tail end of the card near the power connector apr7165a vwa32

I am comparing my card to those that have been listed and am thinking that maybe some chips have been combined to make this an ultra-non-friendly-reference card. I am tempted to just buy a 7850 when they come out next week but thought I'd try to fix this up.

So my questions are: Any idea which one of those 8 pins to jump? And if I did said jump with IGP, would this trick still work, or do I need to go out and find me a straight PCI video card (only one PCIE slot).

Help is much appreciated.
