The Samsung Galaxy S4 will go down as one of the most well-known smartphones in the South Korean phone companies history and the LTE variant comes with some sweet speed.

What better way to put that to good use than following the guide below to unlock the internal hardware and free it from the restrictions that were holding it back? If you have recently found the official XXUHOB7 over the air software update arriving and want to know how you can root that, all you need to do is following the easy guide below.

What Is Rooting the Android Operating System?

When you buy a new smartphone, you might not know it, but the Android operating system is in a “locked” state. For the most part, it will not make much difference to you: most apps are still available to use, and there are benefits to this locked state such as better security. When you root the Android operating system, you are gaining full administrative rights over the OS.

Why Would You Want to Root Android?

Gaining full administrative rights over the operating system has some perks to some people. For example, out of the millions of applications available on Google Play, some of them will not be able to run on your device unless it has root access. Until you have a specific need for wanting Android rooted, you probably want to leave Android as it comes out of the box. But if you need to unlock an app, then that is when you want to look into rooting methods. Using more apps is only one example of why you may want root access, here is the full list of benefits:

  • Unlock more applications. Some of the apps available for Android cannot run unless you have root access. This is because the app’s features cannot run without the root permissions because the features require the full system access before they can be useful.
  • Better battery life. Smartphones are great, but they have one caveat, which is each time you recharge the battery, it loses some of its overall lifespan. That means smartphones, in general, do not make great investments, and if your weekly paycheck is low, you will want to limit the number of smartphones you go through. One of the ways you can do that is by removing bloatware and creating a better battery life.
  • Bolster performance. If you are the budget-conscious shopper, you may want to increase the device’s performance. This can be done by removing the bloatware as well. The more processes you have running, the more memory that is used. By removing some of the apps, it can help lighten the load on your hardware.
  • Customize Android with themes. With root access, you can download and install any theme that’s at your disposal. That includes any customized theme you can find.

What Are the Risks of Rooting?

If you are buying a smartphone that is not running iOS, then it is probably the Android operating system that you want running as the ideal software to pair with your shiny new hardware. It is, in fact, the Android OS that offers you the chance to customize the OS considerably more than iOS: custom themes, run any app you know about, the works. For many users, the “openness” of an operating system is important, because it offers them more freedom which means running into fewer problems with their investments. But there is a reason iOS likes a far more locked approach: the ability to customize is not for everyone, and if you do not know what you are doing it can lead to a lot of problems which can define your time with the OS rather than freedom.

With power (full admin permissions) comes greater responsibility. Here are some of the main risk factors when it comes to rooting:

  • Malware becomes a larger threat. You might read the occasional news article about how new malware is wreaking havoc in parts of the world on Android. But the Android operating system with root access becomes considerably more vulnerable to exploits because applications are no longer prisoned off in their own sandbox environments. This means if you accidentally download malware, it can do more damage because it can spread throughout the operating system and even jump into other applications and potentially view sensitive data.
  • You can accidentally brick the smartphone. There is always a chance that you end up bricking the smartphone before you had the opportunity to use it with root access. That is because if you are going to brick it, it is going to happen during the rooting process.
  • You may void the warranty. Most manufacturers do not allow you to root the Android operating system and still get to bring it in for repairs under warranty. Whether they are legally meant to do that or not is another question, but it is now common knowledge that most do not want to help you if they find out you have unlocked the OS with root access.


  • One of the major issues people have with rooting is that Google patches the current exploit and flashing older files can brick their device. Avoid that by only following the guide below running XXUHOB7. That’s easy to check by going to Settings > About Device > looking at the build number.
  • The Samsung Galaxy S4 comes with a few different model.This OTA only rolled out for the LTE I9505 variant. Make sure that’s the one in your hands.


  • You ought to download and install the Samsung USB Drivers. Follow the link and scroll down to where it says Samsung. They’ll download to the computer. Now restart the computer for the drivers to start working and continue with the guide.
  • Understand that rooting with the guide below does indeed void any remaining warranty you had with Samsung. You can follow a guide to unroot the same device and return the flash counter back to zero and send it away under warranty again.
  • Check that you have enabled the USB Debugging Mode first by navigating to Settings Developer Options > USB Debugging.


1. Download the SuperSU from this link.

2. Connect the S4 to the computer with its USB cable.

3. Transfer the SuperSU zip file to the internal SD card storage without unzipping.

4. Unplug the phone from the computer.

5. Completely power down and reboot into recovery mode. (Volume Up + Power + Home at the same time.)

6. Navigate to the “flash zip from SD card” option inside recovery.

7. Use the Volume keys to move around and search for the SuperSU file. Confirm the upload.

8. Wait until it finishes installing before heading back to the main recovery windows and selecting the “reboot system now” option.

That’s it. . . . You are now rooted. You might want to go to the Google Play Store and install Busybox.

Now that you have root access to the Samsung Galaxy S4 LTE I9505 smartphone you can start installing whatever root applications you want. Most of them are available from the Google Play Store while a few extras have been kicked out of Google Play and have links available at XDA-Developers instead, or just never wanted to be on Google Play and have links coming from websites that the developers have set up for them.

We always suggest installing as many root applications as you can from the Google Play Store because downloading files comes at an added risk whenever you download them outside of Google Play. Google maintains the Play Store and has many employees protecting it from stuff like malware and always removed any app that is suspected to be malware whereas the other sources around the web aren’t being looked after by Google and sometimes aren’t being looked after by anybody.
