Question [Q] i337m 4.4.2 rooting with ubuntu

I recently purchased a Galaxy S4 i337m (Canadian) and have been desperately digging around for a method of rooting that does not involve CWM or custom firmware or anything, I just want to gain root access.

I stumbled across this site: which offers a general root any android tutorial. With my basic understanding of linux/unix commands, it seems promising.

I was just wondering if someone with more experience could have a look and tell me if this method would work with the i337m.

Before you start telling me to just use Odin, I'm running Ubuntu
