Rooting the Korean Samsung Galaxy S5 smartphone running on the Android 6.0.1 Marshmallow update can now be carried out by using an updated version of the CF-Auto-Root tool by the developer, Chainfire. Chainfire is the guy behind the CF-Auto-Root tool since the very beginning of when it all started. The CF-Auto-Root tool has its own repository and it’s up to us to distribute those files or you guys to understand what you can do with them. The new file that is available for the Samsung Galaxy S5 smartphone from Korea has been specifically made for the Android 6.0.1 Marshmallow updates, so this will work for all your firmware versions as long as they are based on Android 6.0.1 Marshmallow.

The Samsung Galaxy S5 from Korea has its rooting method based on the MMB29M.G900SKSU1CPB9 firmware which rolled out to some regions around the world as part of an Android 6.0.1 Marshmallow software update. The firmware doesn’t need to have arrived for your region because you do not need to be running the firmware. The developer of the CF-Auto-Root method, Chainfire, says that some of the Samsung devices will not boot older images. You only need to use this firmware build number as an indicator for is you need to update yours to something newer.

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.

  7. Wait around five to ten seconds for the blue or yellow ID: COM port color coming from the Odin user interface letting you know that the device is now connected to your flashing tool.
  8. Click the AP button from the Odin user interface and browse the desktop for the Galaxy S5’s rooting file that is sending in the tar.md5 extension.
  9. Click on the Start button and then wait for the S5 smartphone to get rooted.
  10. Look at the display of the S5 smartphone and wait until you can see it saying that it is flashing the SuperSU application, clearing the cache partition and then reflashing the stock recovery.

In conclusion, that is how to root the Korean Samsung Galaxy S5 smartphone running the Android 6.0.1 Marshmallow updates using the newer version of the CF-Auto-Root tool by Chainfire.

Anyone who does not find the guide works for them can check the Samsung Galaxy S5 smartphone got into recovery mode during the end of the flashing. Chainfire states that no recovery mode at the end of the guide means your device will not be rooted. You can fix that by booting into the recovery mode manually after the flashing completes. Moreover, you can try installing one of the other versions of the Odin flashing tool from our downloads page and check if that helps.
