I have a DroidX this is my first root attempt. I am using z4root to "permanently root" the X. I am a little concerned because it has been trying to root for about 40 minutes now. Can I kill the app without damaging my phone? (I don't have anything backed up I ran across http://androidforums.com/evo-4g-all-things-root/194918-rooting-dummies-extras.html after starting the root. I wish I had seen it before. I would have done the pre-root steps).
