[Q] XT1053 Need help with Root topic

I have the dev edition of the moto x 2013. I've unlocked the bootloader successfully. I flashed the Recovery img with this command

Code:

---

mfastboot flash recovery openrecovery-twrp-2.8.3.0-ghost.img

---

and flashed the SuperSU.zip (UPDATE-SuperSU-v2.40) through the Recovery successfully. But when I checked to see if it was rooted with Root Checker Basic, it said the Device wasn't.
I'm sure that I've done all the steps right in this guide Guide on "Rooting Unlocked Bootloader". Please Help
PS: I'm new to all this rooting and stuff. Sorry if there is a post out there that covers this. I couldn't find any posts that say this guide didn't work.
