So I am wondering: could be the device id an issue? It is written as new 731F with succesfull flashing, but after if I read it again after a reboot with shortpin, I see again the previous one 7310. Here some screen about the linux error (2 x 5700xt - one working one bricked):
Stripping wire is thin enough that you cant break a leg of the chip. About SOIC8 clips, if you cant get a reliable read, consider soldering with stripping wire straight to the IO ports. The point is that after the flashing the behaviour is still the same, not seen even from win10 or Linux, the only way is to start with a shortpin. When you are flashing a bios as the other poster mentioned, you want to be sure you have the right file and you will be able to restore it. I am really wondering now about the deviceID, as it seems to be currently wrongly 7310, and the correct and new one 731F. So here I have tried to flash via UEFI Boot, with the BIOS I suppose to be the right one (unfortunately I am not sure as I got the card already bricked):Īs you can see the flashing is succesfull. Here an update, yesterday I was able to try the card with another working 5700xt as primary card with monitor connected: if I do not short the pin, the second and bricked card is not recognized at all, if I short the Pin I see that card with errors. I am in the very same situation, so maybe those info can help also Eertonhs. I have managed to POST by shorting the Bios pins 1 and 8 (Paper clip method), but the amdvbflash 3.04+ Win would not flash (error F0L01), so I used amdvbflash 2.93+ to force flash the previous bios into the card. That bricked the card and the computer would not be POST.
Then I have flashed the RX 5700 with the modified Gigabyte bios (see msi.rom) using amdvbflash 3.04+ Win (the same process I did with the Mech card). In order to do this you need to spend 20 dollars, (10 for the bios flasher, and 10 for the amazing solderless bios clip) read my story above to find the amazon links, or just look up (CH341A and get the one thats like all black) along with the (CTYRZCH SOIC8 SOP8 Flash Chip IC Test Clips Socket Adpter Programmer BIOS/24/25/93). As the Bios on the Mech card was performing a lot better than the one I had on the RX 5700, I followed the same procedure that I used to get the Gigabyte Bios working on the Mech card (replaced the Sub Vendor and Sub Id by the original bios values). The other card I have is a MSI RX 5700 that was flashed with the original MSI RX 5700 XT bios. This Bios is really efficient and increased speed and reduced power consumption on my Mech card by about 20W. I have 2 cards, one is a MSI Mech RX 5700 XT, which I have flashed successfully with a modified Gigabyte Bios (see attached Mech.rom).
