need some help to flash back a RX470

[krrkrr]

Hello everybody...

I've recently bought a used RX470 but it seems it was flashed for mining... I should have paid more attention when I bought it, but it was cheap and, most important part, it a version with NO fan, which is quite important for me. It only have one HDMI port and nothing else. It's fine by me as I'm gonna use it with a single 40' display. I had no information about the manufacturer and the seller quickly disappeared. I'd like to try flash it back to the original firmware, which I don't have, of course. That will be my first time flashing a graphic card -___-'

I got a PC and the display is using the iGPU, and I see the card in HWinfo... it says : AMD Radeon RX 470 (Polaris 10/Ellesmere Pro) [PC Partner/SAPPHIRE]. So, I guess it's a SAPPHIRE RX 470 ?

I know there's a deposity here with some firmware... I'd like some clues... where to begin and the mistakes to avoid (except the first one: buying a used card without checking details first... huhuhu)

thanks !


EDIT: I've downloaded furmark/GPU-Z/Shark and so, it definitly said it's a sapphire. There's a lot of informations here, with these softwares... I got no idea what to do with that...

Would you be and make some pictures GPU-z main screen

 

[Imperator]

hello
In order to narrow the search for the right BIOS for your card, we need the following pictures :
- one picture with labels from the card
- one picture from GPU-z - main screen
- one picture with GPU-z > advanced tab > and from drop down menu you choose memory info

 

[krrkrr]

gonna do that ASAP

Edit: here u are... but there's no "memory info" in the advanced tab, so I choose AMD Bios, instead as it seems there's info there...

 

[krrkrr]

and here are the memory timings

 

[Imperator]

Hello.
Based on your card ID, subID and memory code, i narrowed the search.
Here you have the right BIOS for your card :

Sapphire RX 470 VBIOS

4 GB GDDR5, 1206 MHz GPU, 1850 MHz Memory

ok.. is there something special to do ? I dl-ed amdvbflash ... I just launch it, select the rom and that's it ? do I do it with a display plugged in the RX470 or should I use the iGPU while doing it ?

EDIT: I installed amdvbflash ... but everytime I launch it with an argument (-h or -i for instance), a windows appears, some texts scroll and then the windows disappear in less than 0,5 s... and nothing else ?! I can't read any of the information here...

Here is a short guide how to made by @eidairaman1

Hello, as it's a RX470 I've followed the second part of the guide, with atiflash 2.93 ... but when I try to launch it, in command prompt, despite the case I'm running everything as administrator, I got a message saying I have to run it in Administrator Mode. Maybe it's because I'm on windows 11 ? Anyway, right now, seems I can't use atiflash 2.93....

I've tried to right click directly on amdvbflash.exe to launch it as admin, same pop up.

 

[Imperator]

Well.
It is possible that you receive that message due to the fact you are using win 11.
I never flashed a card under win 11
But, CMD with admin privileges should work the same under win 11 compared to win 10.
What about your account on the computer.
What level you have there ?
If you are a simple user you will need always the admin to approve your actions.

 

[krrkrr]

There's only account, on this PC... and it's an admin one, of course. would it be easier on Linux ? I can boot the PC on a live USB linux... in that case, which distribution is better ? I guess Debian is aways a good option ?

 

[Imperator]

well, can you take the card to a PC with win 10 ?
Would be easier this way

 

[krrkrr]

I guess I still can boot the PC on win 10 with a USB ssd... or install Win10 on a second drive... gonna see what's best.

@eidairaman1 I guess someone needs you once again

 

[Imperator]

@eidairaman1 I guess someone needs you once again

Hello.
I can manage the problem.
But we need to solve the problem with windows

 

[Solaris17]

Well.

No it works fine something is wrong with his install

 

[Imperator]

No it works fine something is wrong with his install

Hello.
No it is not.
I tested myself onto my win 11 computer and i receive the same error as he does.
So yeah, it is something regarding the win 11.

 

[Solaris17]

I do it and it works fine

 

[Imperator]

Take a look

I flashed more than 200 cards until now so i know what i am doing
I opened CMD with elevated privileges (admin) but i still got that error as he does

 

[Ruru]

Try other version of the flasher. I had the same error when I was playing around with RX 460.

 

[Imperator]

If i use this version (which is known to be the perfect match for Polaris) on win 10 , i can flash 1000 cards w/o any error.
As i said earlier, i flashed more than 200 cards (Polaris).
And i never encountered this error on computer used for flashing cards. (win 10 22H2 - x64 version )

 

[UHeinz13]

Have you ever tried to flash it from safe mode? And have you used admin rights to flash it?

 

[Imperator]

In safe mode you can't flash a card.

 

[krrkrr]

Try other version of the flasher. I had the same error when I was playing around with RX 460.

which one ? 3.31 ?
what would be the difference with using the "old" one that was advised ?

Anyway, I've installed a win10 on a second drive.. and then flashed the RX470... is there a way to test if the BIOS is not the "normal" one ?

 

[Imperator]

Hello.
You have to download and use version 2.93
