Root/Unroot Android Phone with z4Root App (Free)
Rooting you Android phone has never been easier! The z4Root app by RyanZA instantly roots your device in a simple one step procedure. z4Root also un-roots your device making it impossible to know if it ever was rooted, and thus saving warranty. The following devices are currently compatible:
Galaxy S, Backflip, Droid 2, Galaxy Tab, Galaxy 15700, Galaxy 3 15800, Droid X, Samsung Acclaim, Xperia 10, Xperia Mini, Huawei 8120, Hero, Optimus T, Garmin Asus A50, Motorola Defy and others.
Download and install the app to your phone and open it. Tap on ‘Root’, your device will restart automatically and will be rooted. You can un-root anytime by just opening the app again and tapping un-root. You can also re-root if it did not work properly.
Note that the un-root option is only available in the latest version of z4Root. Other versions might not have the re-root and un-root option. You can get the latest version of the official z4Root on Applanet for free (search for z4Root), since it was pulled down for some reason off the Market.
I shall keep posting articles on awesome apps that require a rooted Android device so you can put the above actions into use. Keep tuned!
