MP 1,1-5,1 Running into errors while upgrading to Mojave on 5,1

Hey there, I'm trying to upgrade from 10.13.6 to Mojave on my 2012 5,1. I have an RX 580 installed, my boot ROM is 9144.1.0.1.0, which I thought was upgraded to 144.0.0.0.0 in the process of upgrading to Mojave. I've upgraded the CPUs to dual x5690s, and I have OpenCore installed so I can boot. I've tried both natively installing Mojave using the App Store download, as well as creating a bootable USB installer; I've tried on both my startup disk and a fresh, separate SSD. I keep running into a fatal error during the installation. The screen glitches out and shows an error log. I've attached the installer log and a video of the attempted upgrade below. Does anyone have an idea of what's going wrong?

9144.1.0.1.0 is a spoofed string thru OpenCore.

You should not run Mojave thru OpenCore.

Also check the real firmware version either with a supported OS like High Sierra without OpenCore or with the Dumper (in my signature).

Ok, so should I uninstall OpenCore and then try upgrading to Mojave? In that case, how do I work around the lack of a boot screen with my graphics card? When I tried installing the 580 without OpenCore, I never got any output, not even in recovery mode. I had to reconnect my old 5770, install OpenCore, then plug in the new card to see anything. My end goal is to upgrade to Monterey, but I read that it’s easier to do that from Mojave rather than straight from HS.

So you either go the update path or upgrade / let upgrade it by reconstruction.

I’m just going to try a fresh install and then restore from Time Machine. Currently following the above guide. Uninstalled OpenCore, going to remove everything but a clean drive and the installer USB, boot, install to the clean drive from the USB, and that should do it, right?
 
This had everything I needed, thanks bro

MacPro5,1: What you have to do to upgrade to Mojave (10.13/10.14 BootROM upgrades instructions thread)

Please fully read this first post, you will probably find that you have one or more problems described into the various notes below. Mojave will only install if you have upgraded your BootROM to the current release and your Mac Pro have a Metal capable GPU*. If you are trying to install Mojave...
