[Help] Tried upgrading OC 0.6.3 to 0.6.4, but bios can no longer find OC. Reverting to old EFI does not help, but USB boots fine.

Most of the information is in the title.

I thought I was doing a fairly simple upgrade here: I simply replaced the relevant files and updated my config.plist as mentioned in the Dortania guide. After booting, my bios couldn't find OC so I decided to revert everything back to my old EFI, but my bios still couldn't find it. I can boot OC from USB fine and I have the exact same EFI in the USB as my MacOS drive, but still no dice. I tried clearing NVRAM, but that didn't help either.

Right now I'm just looking for a way to revert everything back to 0.6.3. I thought having the old EFI would be sufficient, but it isn't. Thanks in advance for any help.
