Recovery is not seandroid enforcing SM-G900F

So I tried rooting for the first time today, and after trying it (and failing) it shows this message briefly with the "Samsung Galaxy S5" startup screen, then turns off again. Then, I noticed I had used a CF Auto Root for 4.4.2, when I was running 5.0. I downloaded one for 5.0 and ran it with Odin. After that I get the same screen, but it stays on that screen forever. It says "Recovery booting... Recovery is not seandroid enforcing. Set warranty bit: recovery" In the top left corner.
Anyone know a fix for this? Not being able to use your phone is kind of sad ;)
