"vbios image not found" issue in amdvbflash GUI

[PortalZero]

I decided to modify the VBIOS to reduce the annoying fan noise of the WX4100 used for fluid motion. I extracted the bios with GPU-Z and backed up the original bios. And while modifying the VBIOS with PolarisBiosEditor (I was stupid when I heard the warning that it does not support it) and flashing the VBIOS with the amdvbflash GUI, the computer got frozen and all operations did not work, so I forced reboot.

Then WX4100 doesn't work with code 43 in device manager. So I tried to flash the original VBIOS backed up in safe mode, but it didn't flash with the message "vbios image not found". Flashing the two types of VBIOS of WX4100 posted on TechPowerUp did not change the situation. What should I do in this case?

Since you saved the original file, you do not have to worry.
Keep it in a safe place.
Then you should start the flashing procedure again.
