Rooting the Korean Samsung Galaxy S5 smartphone is ideal for anyone who wants to start installing additional apps from the Google Play Store that require root access to the internal system to run. There are oodles of these apps, and none of them will work without root access. You can also find many apps available from outside the Google Play Store too! J. Rummy’s website where you can download the ROM Toolbox is one example of an app that needs root access to the internal system to run and is available on the Play Store. You will need to be careful when checking for apps outside of Google Play, though because a device with root access is always a device that hackers would love to be using.

Anyhow, users of the Korean Samsung Galaxy S5 smartphone with the SM-G900K model number can now install the Android 6.0.1 Marshmallow updates and then root it by using the CF-Auto-Root file by Chainfire given in the guide below. Those of you who do not have a rooted smartphone can install the over the air update frequently and then root the Galaxy S5 by using the guide below. Others will need to install the new firmware manually. We Redmond you install the firmware for your model number and region from the Sam Mobile website because it’s the most trusted source. The problem with install firmware for free is they make the downloads happen to slow down on purpose to try to entice you into paying for a quicker download speed. Anyone with a job should consider doing it, especially if you plan on rooting a lot in the future and updating many times. Those wishing to stay on the free download will need to set aside the better part of a day and let that firmware download which can be a pain if your computer sleeps automatically. Make sure you adjust your sleep settings if you are going to the slow download.

The CF-Auto-Root file that is in the guide is based on the MMB29M.G900KKTU1CPC2 firmware. The build ID is given to you to use as an indicator only. It does not mean that you need to be flashing that firmware on your devices. The rooting tool in this guide should work for any firmware version that is based on Android 6.0.1 Marshmallow. The only thing you need to do is make sure you are using the SM-G900K model number. Any other S5 model number will get bricked if you flash the file in this guide.

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.

Files You Need

  • Download the Samsung USB Drivers file for your Windows computer running a version of Windows operating system from here.
  • The Samsung Galaxy S5 can get software updates that update it to a new version of Android — that’s what’s happened here with the Android 6.0.1 Marshmallow. Sometimes the new updates can bring new bootloaders with them. A new bootloader will often cause a smartphone like the S5 not to boot or not flash until Chainfire updates the file. All changes that Chainfire makes to his files will be reflected here because we are linking directly to Chainfire’s repository. You can leave a message a the official CF-Auto-Root thread at the XDA-Developers website and post the new recovery.img if you notice a file that needs updating because of the new bootloaders.

The smartphone will reboot by itself now, and you can open the Google Play Store and then download the root checker app. The root checker app comes in a free version and will verify that your device is rooted in just a few steps.

What is more, there will be occasions where people follow the guide, and it doesn’t work. There are several reasons for that fact. The main reasons are always the drivers. Assuming you have your device detected by the Odin flashing tool, the next problem is the device not getting into recovery mode. It’s hard to tell if your device got into recovery mode at the end of the guide because it happened so quickly. However, if you suspect that might be your problem, you can solve it by booting into the recovery mode partition using the hardware key combination for that recovery mode as soon as the flashing completes. The last problem people will find the version of the Odin flashing tool not wanting to work for their devices. You can solve that problem by installing another version of the Odin flashing application and trying again.
