Having access to the Android root file system so we can tweak it to its fullest extent is what we refer to simply as having root access. Once your device has root access, you can install all the apps that are available from the Google Play Store and not just some of them. The reason being is because many of the apps require root access to work. Those apps are often some of the most valuable applications once could use. You might want to increase the device’s performance by overclocking, increase the battery life, remove the stock apps that you consider to be nothing more than bloatware on your device, or you might even wan ta free WiFi hotspot. All of these apps rely on having the root access to operate.

Getting root access is often easier said than done, however, with many devices getting regular patches in software updates and rooting tools just being difficult to use. Samsung devices are always some of my favorite devices since they have Chainfire making rooting guides using the Odin tool — a method that’s not exactly straight forward, but easy enough and fun to do once you get the hang of how it’s done.

One rooting method that’s always easier above all others is using a dedicated universal one-click rooting tool. These tools are the easiest since they only take one click and you’re done. The latest one-click rooting tool that’s universal is the KingRoot tool. As long as your device is one of the ones on the list given below, you can root it with the KingRoot app running Android 3.0 Honeycomb.

Rooting your Android device using the KingRoot app

  1. Download the KingRoot app from the XDA Developers page here. You will see the link in the first post on the page.
  2. Download the APK file directly to the desktop of a computer.
  3. Connect the Android device you want to install the app on to the computer with the USB cable.
  4. Transfer the KingRoot app APK over to the devices internal storage SD card. Make sure it’s on the root of the SD card, which means on the topmost folder.
  5. Now unplug the device from the computer.
  6. Learn how to install any APK file on your Android device if you don’t know already. You can do that with a File Manager.
  7. Now launch the app once you have it installed on your Android device.
  8. Tap the Root button you will find on the inside of the app.
  9. Wait until the rooting tool pings back the answer from its own cloud servers on how to exactly root your device.
  10. Now watch the progress bar appear on the display and show you how long left.
  11. Once it is done, you will see a success message on the device’s display.
  12. Exit the KingRoot app and download the root checker app from the Google Play Store.

Once you exit the app, you will see two other apps there: King Master and King user. The King User app is the equivalent of the SuperSU app and if you open it up you can unroot your device. That’s how you get rid of the King User and return your device back to stock if you want to send it away for free repairs under a warranty.
