Rooting the Samsung Galaxy S4 smartphone wasn’t all that common to do at first because many owners didn’t want to risk potentially bricking the device. However, once you realize how safe something like Chainfire’s CF-Auto-Root tool to use is, you should have no trouble taking the leap of faith. Some things can prove difficult; getting the Samsung USB Drivers working, finding a compatible version of Odin and not forgetting to put the Galaxy S4 smartphone into the download mode are three things, but once you get the hang of it, it’s easy to see why it is such a popular thing to do. Rooting the Android operating system is not difficult, and it is not as dangerous as it may seem. What Chainfire does is effectively install and enable SuperSU on your Samsung Galaxy S4 smartphone so it can give you a way in which you can install apps that need access to the root file system to run while still managing to keep your device safe. Keeping the Samsung smartphones and tablets safe is precisely the reason as to why the Android developers choose to lock it with restrictions so that nothing can have access to the root file system. It was the only solution they had to keep you safe. SuperSU is the most logical solution to that problem to date, but it requires you being alert which is why Android will never sell a device and recommend it that way off the shelf.

The SuperSU application works by blocking everything, to begin with, but it also has the power to let anything through. SuperSU gives you a message on the screen after you install an app that asks for root access to run, and it is then up to you to choose to allow it or deny it based on your knowledge. All experienced Android users should have no trouble denying access to the root file system when prompted by a potential threat that you do not recognize. Further, they should have the obvious hand-eye coordination to allow everything root access that they installed and already know and trust. As such, there are two keys to using a rooted Android operating system successfully: knowing what a threat is and knowing what to trust.

REQUIREMENTS

• The following guide is made for the Samsung Galaxy S4 smartphone that has the SHV E330K model number (LTE-A variant) and not any other. Flashing the CF-Auto-Root tool that is available in this guide on any other device will result in that device being bricked down more often than not.
• You must have a computer that is running any version of the Windows operating system to use the Odin flashing application associated with this guide. The Odin app which is made by Samsung developers will not flash from a MacOS or Linux distribution.

BEFORE WE BEGIN

• You might need to unlock the Developer Options menu on the Samsung Galaxy S4 smartphone before you can find the menu available from the Settings. You can get that job done on your Galaxy S4 by tapping on the Menu > Settings > About Device > Build Number at least seven times. You will get a message when you have touched enough times that lets you know that you are using the phone as a developer which means the Developer Options menu is now officially available from your settings.
• Head to the Developer Options menu now on the Samsung Galaxy S4 smartphone by tapping on the Menu > Settings > Developer Options > USB Debugging Mode. Once you have tapped over the empty box so that it is no longer empty, you can navigate out of the Developer Options menu and find the settings will remain the same.
• Download and install the Samsung USB Drivers on the computer so the Samsung Galaxy S4 smartphone can connect to the computer and then be detected by the Odin flashing application.
