Hi. I stupidly flash this rom: [Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)](https://bitcointalk.org/index.php?topic=1670733.msg16829112#msg16829112) using atiflash and ended up with a partially bricked card. I tried to unbrick as per: [Reddit - The heart of the internet](https://www.reddit.com/r/Amd/comments/3nxhju/my_semidetailed_guide_to_unbricking_an_amd_gpu/) but kept getting the dreaded “failed to read rom 0fl01” when trying to flash back the factory rom (which I backed up using atiflash. The card is recognized by windows and I can mine no problem. However after rebooting drivers were re-installed automatically and now it seems that things are back to “normal” somehow?
The -ai below seems to show dual bios? Could this be the case? I tried search for info but could not find anything.
Based on the below does it appear that back to stock? I’m runningn claymore v3.1 with a few settings tweaked. Fairly happy with results. 1x Rx470 4gb, 1x Rx480 4gb, 2x rx 480 8gb.

Any chance your GPUs have a dual bios switch ?
You might want to flip it and see

I assume it a physical switch. I checked, doesn’t have one. Strange thing is I believe through the process of trying to flash back to stock something worked
