Are recent samsung updates preventing rooting? I have an S4 that I plan on rooting but I couldn't find a guide on how to do it and some post saying that it was risky.
I know it's an old post, but did you root in the end. I found many tutorials for your device. As For the risks, well, there are many risks when tampering with a phone, but rooting is fairly risk free. It's what you do to it afterwards that can cause bricking etc. I have a rooted htc1 x +, but before I made the decision to root I spent weeks and weeks learning about root and how to root, moreover, whether I really needed to.
I found this, it might help you decide...http://lifehacker.com/rooted-vs-unrooted-android-your-best-arguments-1599101019
