Well I have seen many complaints from people who have tried to root, only to have the root fail as the command prompt window says that it cannot push the required files to complete the root onto the phone (often times including the words busy box and a list of nonexistent directories - see photo) If this happens to you, follow these steps, and the root should succeed. 1. Once you receive the errors, your phone should reboot, if it does not, Reboot it. 2. Open the SignedBackupTest APK again. 3. When you see the words HELLO WORLD hold your power button for three seconds, and select POWER OFF AND RESTART. 4. When your phone reboots, connect it via USB to your computer, be sure that the phone is in Charge Only mode. 5. Double click root.bat to open it again. 6. The root should succeed this time. If it does not, repeat steps 1-5 until it is successful. This also happened to me, and i have seen at least 5 other people who have suffered from this result as well. Once you get a successful root, you may encounter an "Insufficient Storage Space" error in the Google Play Store, if you do, I have a thread available to learn how to fix that as well. Thanks for reading, hope this helps some people.
