5.00+ CFW Will Not Boot

[HermXIV]

I do not have one of those motherboards. If I did, then how would I even be able to still use it? That comment does not make sense.

And I don't think you understand. I have tried that method to use a CFW higher than 5.00, but it causes my error when I do. No matter how I do it. That is what I am trying to solve. Why that happens.

Then what is your motherboard's version?
