Problems With Downgrading my New S5 To Kitkat

Hello All, just need a bit of help here. I'm in a bit of a bind, I really dislike Lollipop and I wanted to downgrade my new S5 To Kitkat. However I've hit some road blocks, I've tried all the firmware downloads for it, the Odin, Kias 3, Samsung drivers, All the good stuff. However when I set everything up I get the error message on my phone of SW rev check fail fused 2 > binary 1 Now I've come to these forums to get this answered but I have a few Ideas, weather it's the fact that the device already came pre-loaded with Lollipop and never had kitkat to begin with is the first and biggest concern. I'm looking for any and all types of solutions, um-installations, removals, roms, roots, anything to get back the be fantastic os that Kitkat was.

Thanks in Advance for any advice.
