Help Root Failed on Samsung Galaxy S5 Active SM-G870W

[Connor]

Hi guys. The title basically says it all. Since there is no Towelroot for the SM-G870W, I have to use ODIN. I follow the steps to the word and I have even tried changing PC ports and switching computers. No matter what when I click start it works for about 5 seconds until it says "Failed" in a red box. Thankfully my phone doesn't get bricked, but I still want to root my phone. Also, I'm positive I use the correct CF-AutoRoot for my phone's model. Thanks in advance!

This is the error I get:
