Hi and welcome! I used to have the Droid X. I used to be an expert at rooting it. That was over a year ago and the Droid X has both moved on without me in rooting info and also has aged to nearly being obsolete.
So.. my advice is to be very carefully, but Moto has encrypted it to where if you're not careful, you can render your phone useless.. permanently. Be careful. Ask the folks in the droid x section for advice. Read the info there. Good luck!
