How to recover from a bad video BIOS flash

Hello! I bought a very cheap(15$) RX580 from a miner, and it turns out is an RX570, by looking at the die.
The card has no video output, so I figured out its a bad flash.
In this thread i posted all the pictures with my card: https://www.techpowerup.com/forums/...rovide-me-a-vbios-for-it.282479/#post-4526941


I found someone's unverified bios, but i cant flash it. Even in the DOS version of atiflash.

I get error 0FL01 , SSID mismatched . Old SSID : E366, New SSID: E353

I tried the unlockrom command, it works, it says ROM Unlocked but the flash will still fail. I figured out that maybe the one of the dual VBIOSes (its a sapphire card) is locked, so i switched to the other side and rebooted, but i still get the same issue.

Can anybody help? I just wanna game on it :P

follow these steps.

1. download and extract the folder "rxflash" onto your desktop.

2. rename the bios file you want to flash onto the card "rxflash.rom" and move it into the "rxflash" folder.

3. run "amdvbflash.exe" as admin. a black window will open up, do nothing with it, just leave it.

4. run "bios flash.bat". this will flash the bios

5. reboot and report back.

By the way,doesnt the fact that amdvbflasher identifies the card as a polaris10 help pinpoint the issue?

Im back. Here are other parameters used to recover found in GPU-Z.

Glad someone finally wrote a current flash guide. I didn't have patience to then.

Thanks @Regeneration

I've been flashing a couple of vbios-es for my mobile 2060 but for some reason my subsystem id, shown in gpu-z, does not change no-matter which vbios I flash. The flash goes through and when I run a test, I can see the gpu draws the correct amount of power for each vbios. Other than that, the subsystem id shown in gpu-z ends in 3F8D but when I flash the supposedly stock vbios, nvflash reads it's id as 3F8C and gives me a mismatch. I can still flash it despite the mismatch. Other than that I can't seem to find a vbios which ends in 8D... I'm wondering if this problem of not changing the id to the correct value will bring problems or if it's a symptom of a problem?
 
How do i tell which pins to short? The last time i tried it started sparking and smoking and now i have ptsd...

If It works correctly dont worry ..if you need an orig vbios and cant find one..download the orig BIOS for your laptop and then there are tutorials you can follow to extract your orig vbios from the Orig bio just google search it ..but again if you 2060 runs good dont worry bout it so long as you lost no functionality.
 
I have a asus rog g14 with a 1660ti max q. I use it connected to a 1440p ultrawide display and it just cant push out good frames for modern games. So now I'm thinking if I can flash the max q bios into a normal mobile bios. The dgpu does not output to laptop display, instead the it goes pass the igpu into the laptop display. So because of that if my flash fails would i be able to flash it back by using the laptop screen.

Your better off overclocking and undervolting your gpu to normal 1660ti clock and voltage speeds using Msi afterburner then you can switch it to 1660ti mode via Afterburner software dont flash your GPU and possibly lose hdmi output etc...or black screen worst scenario you cannot boot your laptop its not worth it..Also you have to see if your laptop has a mux switch in bios that allows you to bypass the igpu and put your laptop in discrete gpu mode for better performance. Any vbios flashing is super risky Msi Afterburner will give you the same results if used properly. Good Luck bro.

God Bless in Christ Jesus to all
 
This is not a help thread but a bios flash guide. If you need help, start your own thread or look through yhe ocean, there are tons relating to RX 500 series or fake GPUs.
 
is possible such evilness? ahha

I am using Rx 5700 xt and I modded the bios with memory timing myself and I could not get any image again. I couldn't get any images in Windows. The bios key definitely didn't work so I ordered a ch341a and with the bios which I think is correct I can read it but I can't delete it (neo programmer ap.) but it seems to be writing. However, although the bios file size is 512kb, there is a chip size of 1mb, so I think there are a few problems.

I tried to take an image with igpu and two graphics cards and I had the same problem every time. The image comes and the image is cut off without seeing the bios screen. Only hdmi, displayport never gives any image.

What should I do, I tried two bios?

[XFX Trible Disspantion 5700XT V1.1 ]

Also, on the ch341a software, puya 25q80h is not available in the chip list.

NeoProgrammer version 2.2.0.10 has P25Q80H listed. Did you place the clip properly?
 
Yes, I tried, I cannot delete for some reason, but the writing process is done properly. The PC starts up and displays the image, but after 5 seconds at most, it stops displaying the image. (hdmi only)
 
I have updated the guide today.

Now its easy and cheap to obtain USB 3.0 and type C adapters to HDMI and even DisplayPort.

You can find one on Amazon for a few bucks and with it you can flash graphics card back.

You will need a motherboard with USB 3 support.

Yeah I asked a user about the mobo specs recently for a possible recovery that way, just a usb 3 display adapter
