Ladies and Gents! I have finally found a successful root method! While it's designed for other XT models through Republic Wireless, it works flawlessly for our model as well! Replace the '@' in the following links with periods, and they will lead you to EVERYTHING you need! Good luck!
FIrst and foremost, install JDK and ADB following the instructions on this link!
Next, follow the steps for rooting on THIS page!
You now have a successfully rooted Defy XT!
