I was able to add the DJI app to mine and fly right out of the box. I have successfully rooted mine using the instructions on the link above. I now have the Play Store, but still cannot add the Utility Pro app. There is an app on the Moverio store that will lock the screen rotation into landscape mode for the DJI app. If you're having trouble rooting, check your software version. There is a developer version and a retail version. I believe you need to be on the developer version to root. (D1.0.5).
