Bricked my PandaMiner (single) GPU

[chiwalfrm]

I have a PandaMiner B3 Plus with eight RX470 GPU's.

I was modifying the BIOS of a single GPU using Polaris Editor.  I even made a backup of the original BIOS for safety using the "atiflash -s 0 backupbios.bin" command.  But during the "atiflash -p 0 newbios.bin" command to program the BIOS, the PC hung.  Now that one PandaMiner GPU is no longer recognized in Windows.  "atiflash -i" shows "unknown SPI" and "fail" under the test column.  Trying to flash again says "Failed to read ROM.  ERROR 0FL01".  As the GPU does not have a BIOS switch or dual BIOS, I am currently stuck and was wondering if anyone has any advice on what to do?

I think you have issues with the eeprom(8 pin). And you can try to flash under DOS. Maybe it will help. But for DOS you need some old PC with Pci Express , PCI slots and old VGA PCI card . If you need manual how to do it , i can help you with this.

But you can use easy to solve this problem. If you have the same bricked card's (GPU crack or such problems like drMOS damaged) or maybe your friend have one of this. You need to pull out the BIOS eeprom from the card and put it in your Panda's GPU card . after this try to firmware.
