Anyone with the Samsung Galaxy S5 smartphone already has a device that comes with a more than capable battery. Conversely, there are many people buying flagships smartphones that do not know how to get the most out of a battery or use a battery efficiently. There is one application out there that you can still called Greenify and it is a household name in the family of root apps one should install. However, not many people really have a true understanding of how the Greenify application really works. Since we are rooting guide experts here at Tech Chomps, we would like to tell you how Greenify works and perhaps even entice you into installing it as one of your root applications to try after you finish the guide learning how to root the Samsung Galaxy S5. We don’t recommend apps because we get paid by the app or anything like that. We do it to try to help enhance your experience with a rooted device.

The Greenify application will analyse your mobile device and let you know which apps are running in the background. Once the analyser has finished running, it allows you to manually choose which apps you would like to put into a state of hibernation, which apps should not be running in the background, which apps should be unable to get access to system resources and which apps you do not want accessing your bandwidth.

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.

  2. You can use this guide running on any firmware build ID number. Chainfire just gives build number for you to look at as an indicator but it does not mean you need to be running that same build number of firmware. Any firmware on Android 5.1.1 Lollipop should get rooted using this guide.

Rooting the Samsung Galaxy S5 SM-G900W8 running on Android 5.1.1 Lollipop

  1. Enable the USB Debugging Mode on the Samsung Galaxy S5 smartphone so it can use the flashing tool on the computer.

  7. Wait for at least five or so seconds for the drivers to start working and then look for a yellow or blue ID: COM port box coming from the top left side of the Odin application on the computer. No light means you need to update the drivers by closing everything down and trying again by installing the universal Windows ADB driver first.
  8. Click the AP button and then browse the desktop location for the rooting file that you had extracted earlier ending in the tar.md5 extension.
  9. Click the Start button and wait until Odin flashes the rooting exploit on your device.
