I have a mining card which is xfx rx470 4gb ,and is flash to rx580 version,
I found out the performance not stable so I get another sapphire bios which is same chip same memory type same clock .
I flash it in the windows using amevbflash using command below.
Amdvbflash -unlockrom 0
Amdvbflash -f -p 0 1.rom. (My new rom name)

BTW I am using amdvbflash 4.68

after awhile it show something said my card will update to another name. And some moment later, it show writing fail.
Ok... I would take that as the update bios is failed.
I reboot my pc and, boom, I can’t see my boot up screen,

I found out that some article said to take a MOBO with internal display and flash it , luckily I do have a working mobo which is msi g31tm-p31.
I choose the display graphics to use internal at boot.
However, the internal display will only work if my display card wasn’t power up.
If I plug in the pcie power into the card. The mobo will choose the display card.(remember? My card is bricked, nothing will show up)
i tried to power up the pc and immediately plug in the pcie power after something show on internal display screen.
And the result is,
No adapter found.

I use amdflash -i 1 or 0 also no adapter found.

what should I do now ?

Instead I got this pm25lq020.

This one should be the EEPROM (for BIOS)

Once you started the computer do not restart it.
And from windows just use the flashing file .
Right click on the ati/amdvbflashWin.exe and open it with administrator rights.

Find the BIOS (original version) for your card and memory chip vendor and flash it.

CH341A is cheap and easy to find.
i tried the programs, in the list do have a similar chip is PM25LV020, but no PM25LQ020 in the database.
