Robert had an HTC Incredible, which someone rooted for him and installed Cyanogen 10. Leo says that's a great way to keep an old phone alive. Now Robert wants to do the same thing with his DroidX, but the person that did the other one isn't there to help him.
Leo says to go to Google Play Store and get Clockwork Mod's ROM Manager. Then he can see what ROMs he can install. If he wants to learn how to root it, he should head over to XDA Developers Forums and he can learn how for just about any Android phone out there.
