To root an Android device, download and install Kingo Android Root onto a Windows computer, enable USB debugging on the phone, and run the Android Root program on the PC with the device connected. After clicking "Root," the utility roots the phone in approximately two minutes.
Rooting with the Android-friendly Kingo Android Root program is a one-click process. The program is free and will usually work with Android devices not even listed as supported devices. After installing the program on a PC, enable USB debugging mode on Android 4.0 or 4.1 phones by going into "Settings," then "Developer Options" and then checking a box called "USB Debugging." On Android 4.3 and later editions, go into "Settings," then "About Phone" and tap "Build Number" seven times before doing the previously mentioned steps.
After running Android Root on the PC, connect the Android device to the computer using a USB cable. When the "Allow USB Debugging?" notification pops up, click "Always Allow From This Computer," and then hit OK. Finally, click "Root" in the program and wait for the utility to root the device. When it's completed, the device automatically restarts. To reverse the rooting process, simply run the Kingo Android Root program again with the phone connected, and hit "Remove Root."
