Lenovo E580 discrete GPU (RX550) error code 43

[georgios22]

The discrete card appears to be dead.
I've read somewhere to try and reflash the VBIOS
If I launch GPU-Z system crashes (BSOD)
Ubuntu also throws error "Unable to initialize device".
Is there any dedicated vbios chip to try and read the bios from with my CH341? Or is it inside the discrete GPU?.
Anything else I can try?

I believe VBIOS is in main BIOS?!

Maybe, i ask because the primary GPU is Intel and the RX550 is secondary. Anyway since i've updated the BIOS to the latest version, that means the GPU bios is reflashed then.
Bummer. Maybe I can try an older version
