Hello there, sorry for just joining here and asking for a solution for my problems, but I recently bricked my Sapphire Reference Design RX 480 8G by flashing a faulty BIOS and it would be amazing if you guys had any ideas.
At first I couldn't even boot to windows but with help of a paperclip and the 1+8 method i managed to succesfully boot, with the "dead" GPU installed, from my iGPU. Then I tried a couple of things:
-ATIwinflash, shows me: Independent ATI GPU cant be found (something along those lines, I translated it)
-ATIflash via administrative command prompt: -i adapter not found. If i try -f -p 0 bios.rom it says: Adapter not found ERROR: 0FL01
-made a bootable USB and tried flashing via ATIflash in DOS, with the same result, Adapter not found ERROR: 0FL01
-I installed the GPU in the 2nd PCIe slot and repeated the steps above
Strangely the GPU gets recognized by GPU-Z to be a RX480, and also the UEFI system Browser shows a generic ATI card in the PCIe slot.
Unfortunately ATIflash doesn't find an adapter installed now matter what i tried.
I would really appreciate every suggestion you got for me!
EDIT:
I managed to see my RX 480 in ATIflash while i hab another dedicated GPU installed in the main PCIe slot, -ai tells me this:
Adapter 1 (BN=07, DN=00, FN=00, PCIID=00001002, SSID=000067DF)
Asic Family : Polaris10
Flash Type : R600 SPI (64 KB)
No VBIOS
-i command results in this:
adapter bn dn fn dID asic flash romsize test bios p/n
======= == == == ==== =============== ============== ======= ==== ==============
0 01 00 00 6938 Tonga M25P10/c 20000 pass 113-4E3081U-X58
1 07 00 00 67DF Polaris10 R600 SPI 10000 fail -
when I try forceflashing after this it always says:
Failed to read ROM
ERROR: 0FL01
Weirdly I can't seem to find it via BIOS version of ATIflash, only via the cmd prompt.
I attached the ROM file I used for flashing the RX 480, it's the bad.rom and the stock.rom file wich I'm hoping to get back on the card.
2. EDIT:
I managed to fix it by myself! In case it helps anyone for the future I tell you what I did:
1. Boot over another dedicated GPU with the bricked GPU installed in the system by using the "1+8 Pin Method". It is very important that you are later able to remove the short with the GPU's installed.
2. Boot into Windows safe mode and deinstall all remaining display drivers by using DDU.
You gonna need a 2. dedicated GPU since at least for me booting over the iGPU did result in "No Adapters found" Error in ATIflash.
3. Boot into Windows run a CMD prompt as Administrator and use the atiflash -i command to see if your GPUs get detected. In my case the RX480(bricked card) stated fail.
4. Now close the CMD prompt and remove the 1+8 short you have done with something like a paperclip.
5. Reopen a CMD prompt as Administrator and repeat the ATIflash -i Command, now in my case it wouldn't say fail anymore
6. Use the CMD prompt to Flash your GPU with a working BIOS
Thanks a lot anyways
