For those of you who want to root your Galaxy S4, here’s another root method using TWRP recovery.
This root method works for Android 4.3, 4.4.2/4.4.3/4.4.4 KitKat, and 5.0.1 Lollipop!
Why another method?
Well, at the time of this video, some models do not have CWM recovery available. But TWRP recovery is just as good as CWM recovery and installation is nearly identical but using different menus.
