If you have owned the Samsung Galaxy S3 for at least a few months now, you will have probably been introduced to a thing called the Google Play Store. The Google Play Store is home to well over a million apps, and most of those apps can run on your device. The way apps are designed has them compatible with the Android operating system so it does not matter what particular device you may own, they will always work. There is one exception to that, however.
Out of all the apps on the Google Play Store up for grabs, there are at least a few thousand that are incredibly useful but unable to run on your smartphone with the way it comes out of the box—even though it is running Android. The reason being is because it does have root access. Having root access on Android is referring to having control of the root user account—the account that has the most permissions possible and the equivalent to the administrators account in Windows. These are called root apps, and all you need to do is follow a guide like the one below to end up with a rooted device and one that has root access. The root apps will then run as soon as you install them and then open them to run them.
- You need to have the Samsung Galaxy S3 smartphone that comes with the SHV-E210S model number to use this guide. If you have one of the other model numbered versions of the Samsung Galaxy S3 smartphone, it will get bricked by using this guide.
- You need to have a computer that is running on any of the Windows operating system versions or else the Odin flashing tool cannot run, and since the CF-Auto-Root tool is only an Odin flashable file, the rooting file cannot get flashed.
BEFORE WE BEGIN
- Chainfire had the KTU84P.E210SKSUKNI3 firmware build number running on the Samsung Galaxy S3 SHV-E210S smartphone when he developed the version of the CF-Auto-Root tool that is linked to in this guide. He does not suggest you need to be running the same just because he leaks out that information. He is giving the information of the firmware just in case it becomes relevant ever in the future.
- Unlock the Developer Options menu  on the Samsung Galaxy S3 smartphone so you can open it up and then turn on the USB Debugging Mode  from its settings.
- Install the Samsung USB Drivers  on the computer before you get going with the guide so that the Odin flashing tool is capable of picking up your device when you connect it to the computer with the USB cable.

In conclusion, that is how to root Samsung Galaxy S3 SHV-E210S smartphones running on the Android 4.4.4 KitKat software updates by using the CF-Auto-Root tool. The one-click rooting tool has just managed to install and enable the SuperSU app on the smartphone, and you will see it after the smartphone reboots. That SuperSU app is already activated correctly, so you do not need to do anything to it before installing your root apps. Jut go and find the ones you wanted to install and run them. The SuperSU then gives you a message on the phone’s display asking for you to confirm that you do want to grant it root access and then it starts working.
