Help Flash MI50 to Radeon VII Pro

[Outhawk]

Hello together,
i got an MI50 16GB 0x66A1 and wanted to flash it to a Radeon VII Pro 16GB Bios 016.004.000.064.015319.
My first try was with the 3.31 Version, it detected the card but flashing didnt work
Second try with the 5.0 Version same problem... but now when i check the Informations amdvbflash shows me Radeoan VII Pro/ MI50 32GB and the 3.31 Version cant detect the card again.
I also tryed to reflash it to the original bios but dont work.
Any ideas or did i already killed the card?
At the first try i changed an entry in the asus bios that win 10 can detected the card but not sure anymore what exactly it been.^^

From what I understand about these cards, it's possible to flash a Radeon VII ROM onto them but they already don't want to POST when slotted into consumer mainboards and then no longer work in Windows. You may need a programmer to write the vBIOS.

Im 100% sure some smart guys already did that and when it been just for fun. With the China Cards it should be work easy just the orignial is a bit more difficult. Maybe i was just to stupid and did something wrong. Ah and at the bios i guess had to activate the 4g decoding correct?

Mmm, I never tried crossflashing when I had the Radeon VII because it didn't have dual BIOS support - thus avoiding the specific problem you ran into. You'll probably need to reflash the VBIOS with a hardware programmer if you cannot reverse it with amdvbflash anymore.

I know the Vega Frontier Edition will flash into WX 9100 and work pretty much flawlessly (of course half DP ports are available since it only has 3 full size instead of 6 mini, no genlock connector is present, HDMI and GPU tach lights don't work) - but no clue about VII into Pro VII or MI50, vice-versa.

I don't know if the "real" MI50's can be flashed or at least flashed easily. Something about having two(/three?) bios' and it running parity & integrity checks on power up & boot.

AFAIK only the Chinese MI50/Radeon VII can be flashed with Radeon VII/ Pro VII bios'.

@damric this i believe is your area

Unfortunately not. I had the MI25, and got help from @DR4G00N and a few others.

I agree with @Dr. Dro probably going to need an spi flasher.

Now that i think about it amdvbflash works on RDNA/GCN/VLIW, not CDNA.

MI50 is Vega though right?

@LabRat 891 dunno how busy you are but you might also be helpful.

MI50 is 'Vega II'. I've had success on MI25s using your Polaris flashing guide (IIRC, the older version was key)

Correct.

Vega (and other) cards like to go into some sort of safe mode after bad boots or crashing. I do not know the exact circumstances, but OP might have luck getting the card 'come back' after some hard power cycling while installed in the system.

I'd pedantically compare the PCBs, but The Pro VII vBIOS is what I'd have looked towards (in OP's position).
You seem to be correct though, going off reddit ( )

I was thinking about vega being an extension of gcn

Ok glad it was successful, I just got tired of repeating the commands over and over to people to flash correctly.

3.15-5.0*** people always forget to install the driver which so happens to remove write protection on the gpu so the firmware can be flashed...

Thank you all for answering! Polaris didnt work because the bios file isnt supported...so no way for a noob to flashing it right?

guess i did it correctly... driver circle-save bios-unlock-try to flash
