Need help with Mac Pro 4,1

Hey fellas, I know this is a hackintosh page but I wasn't sure where to look for this kind of thing. I have a flashed mac pro 4,1 to 5,1 and I'm trying to install unsupported Catalina. The problem persists where I'm at the installation where it's 3/4 of the way done. Then the system restarts and goes into the install wizard again. If I unplug the usb. I get a blinking folder with a question mark showing no operating system. Any ideas? Thanks.
