Yeah actually I figured out the problem was actually. It was that there was a really rare group of people that would error out while downgrading if they were on 9.2.This guy right here.
Fair warning, I DID error on my first downgrade and landed myself a nice brick, but that was on emuNAND, so it was fine.
I then followed the first edition of the guide and downgraded sysNAND directly, which I really don't recommend.
The second edition is much better.
Any luck with the second edition of the OTP guide?
