It's my AMD device and flashed it to 570. But seems vbios is damaged by upgrading 570

This is my AMD and I flashed with 570 but it didnt work.
How can I find the compatible bios with 2048sp?
@Gigamaxx Yes, it's pulse "2048sp". Whats the solution then?
I thought I could possibly resolve issue by using fake ID coz the device ID is same
By following OpenCore GPU Spoof, I changed device ID as 0x6fdf but it still doesnt recognize GPU
Yes
One curious thing is my GPU is Sapphire Pulse Radeon RX580 but Big Sur says it's Polaris RX580.
And I followed your video but when I build kext, it says signature is invalid
