Help! Can't boot after accidentally updating to 10.4.6! Hangs at a black screen.

So I'm an idiot and accidentally updated from 10.4.2 to 10.4.6 without updating Clover or kexts.
The install seemed fine but now when I try to boot it hangs at: busy timeout, (60s): 'AppleACPICPU' before going to a black screen. (pic attached) The monitor stays on and if I hit a key the screen briefly flashes white.

I found people here having the same issue:

As suggested, I updated Lilu, Whatevergreen, and AppleALC on my Mojave install USB EFI partition. When I try to boot off the USB it only takes me to the installer screen or hangs at the same black screen, I still can't boot my Mojave Install. I selected the USB drive in the boot priority menu.

Seems like I need to find a way to access my EFI and update Clover and the kexts? Is there a way to do this from Windows? Since I accidentally updated I don't have a recent Time Machine back up so I would rather get my old installation working. Thanks in advance for any help.
