MP 1,1-5,1 Help me with my Mac Pro 5,1 in Catalina Patcher

[Zheng_Qing]

I just bought a Mac Pro 5, 1 with macOS Mojave and hardware: Dual x5695, Nvidia Quadro 4000 mac edition, and 32g ram. I plan to upgrade it to Catalina to support my AMD RX 5700 card. So I used the Catalina Patcher.
I did exactly as the tutorial video shows:
(1) Create the bootable driver
(2) Get into recovery mode and flash the target hard disk to APFS.
(3) In recovery mode, selected "Reinstall Catalina" and wait it until it rebooted (finished part of the installation). Then it finish the second part of installation, it will rebooted again. (Note that in my case, there is no some command line messages during the process)
(4) Then into the "post-install patches" and applied the default patchers for mac pro 5,1.
(5) Reboot... then it stuck on this screen (a bar with a circle) forever.

Note that I didn't do anything about the "APFS BootROM Support" issue mentioned in by DosDude1. Since I thought that my machine is already Mojave before upgrading. So the APFS BootROM should no problem.
Can any one help me with this issue? I have tried several time and it always like this. Is there any mistakes in my process? Or is this situation cased by the hardware (such as old Nvidia GPU)? I really appreicate your help!!! Many thx!!!

I think you need to take a look at this thread: Obsolete, Use OpenCore instead | What you need to do to make Catalina work with MacPro5,1

I don't deal with the 5,1 anymore myself, but I know a lot of people here are still passionate about it.
