Hey, guys, this is my first time rooting one of my phones. My buddy has rooted like 5 of his, so, I asked him how to..he said to skip doing all the complicated stuff and just use the z4root app. So, I downloaded it, turned my phone off, back on, opened the app, and clicked perm root. Well, I've tried four times now..it sits on the screen with a spinning loading circle and says "running exploit in order to obtain root access..." on the bottom. It usually does this for 5+ minutes..and then it just freezes. I don't know what I'm doing wrong...seeing as this is a one button click app..haha. Could someone please help!? All my software is up to date.

Thanks, man! Really appreciate it!
