Rooting the Android operating system that is running on the Samsung Galaxy S4 smartphone LTE is the only way to get your phone to accept the applications that require root access to run. What you are doing is changing the way your operating system thinks so you can tinker with the operating system for the first time. One of the ways we can tinker is by installing apps you could not before. The apps can be powerful like the Device Control app that can change the frequency of your GPU and CPU, or fun like the Xposed framework which can modify the way your operating system is designed. Most of the appeal with rooting comes in creating software that is a better match for your needs instead of accepting the same Android software that has rolled out to everyone and might not completely satisfy anyone. With the rooted Android operating system, we can tailor features, looks, and performance to something that better suits our needs.
- The following guide is made for the Samsung Galaxy S4 smartphone that comes with the SHV E330L model number (LTE variant) when it is running on the Android 4.4.2 KitKat software updates. You will need to have that same SHV E330L model number version of the S4 smartphone or else your handset is likely to get bricked when you flash the file found in this guide.
- You must have a computer that is running the Windows operating system to use the Odin flashing application that is part of this tutorial. The Odin application will not get the chance to run if you are attempting to follow this guide from a MacOS or Linux distribution.
BEFORE WE BEGIN
- Anyone who doesn’t have the Developer Options menu unlocked on the Samsung Galaxy S4 smartphone will need to do it now or else you cannot turn on the USB Debugging Mode. You can unlock the Dev Options by tapping on the Menu > Settings > About Device > Build Number. Tap the build number at least seven times and it will soon say that you are using the device as a developer now which is Android’s way of telling you that the Developer Options menu is officially unlocked and ready to use
- Enable the USB Debugging Mode from within the Developer Options menu by tapping n the Menu > Settings > Developer Options > USB Debugging Mode.
- Download and install the Samsung USB Drivers on the computer  that is running Windows before you get started with the guide so the Odin flashing application can detect your smartphone.
