Hackintosh (i7-9700K+5700 XT) not booting up after switching from integrated graphics to GPU

[lawmaster]

I followed this guide (https://github.com/shiruken/hackintosh) and successfully installed Catalina on my PC.

However, after I get to the step when I switch the output from integrated graphics to GPU, the computer no longer boots and gets stuck at the "GIOScreenLockState 3" line and not going to black-screen. Nothing works unless I switch back to iGPU and boot using the EPI backup on my flash drive.

I've searched everywhere and the solution always seems to be to add the agdpmod=pikera boot argument, which I have done according to the guide. Is there anything else I can do?

My specs are:

• Intel Core i7-9700K
• Sapphire NITRO+ Radeon RX 5700XT 8G
• Gigabyte Z390 AORUS PRO WIFI

Any suggestions?
