need help rooting my GS4 SGHi337m

Hi mrphloid, we have a few tutorials to help get you started. Here's a guide we wrote a little while ago to help you root your S4. I would suggest you read up on root first to make sure you know what it entails and what you can do with it once you have it. Here's a short introduction to the major terms used in rooting and custom ROMs. Here's some more info about wiping your phone after gaining root access and here's a little more information to help you decide what kind of ROM you want to install on your S4. Here's a basic intro to the major custom ROMs around, and a nice database of custom ROM features created by a member over at XDA Developers. That should give you some bed-time reading to get started with and help you decide what you want to do once you have root access and the many joys of the custom ROM scene. let us know if you have any questions.
