There will always be a myriad of reasons why people with the Samsung Galaxy S5 smartphone would want to root the device. One of those reasons that is often overlooked is the GL Tools application. Root apps are the main reason to root a device and not install a custom ROM as many people think. The GL Tools app is one of those root apps that is useful, especially to anyone who loves gaming. Our smartphone hardware is getting better by the year, but gaming requires some heavy duty hardware packaged inside such a small shell that it is often unrealistic to think that we can play some of the best games out there without them having to be produced in size, or without the display on our smartphones suffering. The GL Tools app is the solution to that problem by giving users graphics that are rendering on your display at a slower bit rate compared with when people do not have the GL Tools application installed.

Here is the whole shebang on everything you need to root the Samsung Galaxy S5 smartphone running on the Android 5.1.1 Lollipop software updates for the T-Mobile subscribers.

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.

OEMs and phone carrier networks can bring out new software updates for a smartphone like the Samsung Galaxy S5. Sometimes when those updates are some of the larger updates that bring new versions of Android, they can bring new bootloaders with them. Chainfire needs to update the recovery images, so the CF-Auto-Root tool works if a new bootloader has arrived. A typical symptom of this problem is if you flash the CF-Auto-Root tool and your device does not flash or boot up properly. You can fix that problem by submitting the new recovery image file to the official CF-Auto-Root thread made by Chainfire — the developer of the rooting tool — over at the XDA-Developers forum. Chainfire will see your post and apply the changes to the rooting file. Those changes will be automatically replaced in our posts so you can continue using our files.
