I have 1 Galaxy S4 that is activated, rooted and working great. Another one, for a friend, is not activated, and I am interested in rooting this phone for my friend. The phone was previously activated and has Internet access. Please let me know how to do this. Any assistance would be greatly appreciated as so much is limited without rooting the phone. Thanks! Also, I'm a total n00b, so please use language like you're talking to a 4-year-old.
