So I have had a rooted, overclocked droid x for almost a month now and I'm interested in flashing a rom. I have looked at all the necessary literature for doing so and I just have two questions. Once I flash a rom, is activation needed for the phone? Additionally, when I want to return to stock rooted, do I just clear data/factory set in bootstrap and restore an earlier nandroid? Or do I have to do the maderstok or SBF method?
