Any Samsung Galaxy S6 smartphone owner who has taken the time to check out some lists of the best root apps will likely already know about the Greenify app. Many people who went to the effort of installing Greenify may have deleted it within a few minutes because the apps user interface doesn’t make life easy. However, we can tell you that once you do get the hang of how Greenify works, it can be truly one of the best root apps going around. The way Greenify works is by hibernating any apps in the background and prevent them from waking up your phone. While a phone waking up doesn’t exactly have us thinking about our poor phones sleep deprivation, it is important to note that a waking app can cause battery drain — one thing we Samsung Galaxy S6 smartphone owners can certainly do without on our devices.

The build number that the CF-Auto-Root tool for the Samsung Galaxy S6 smartphone running Android 6.0.1 Android versions is based on is MMB29K.G9200ZHU2DPC6 firmware. That build number will be running on some of your Samsung Galaxy S6 smartphones, and it will not be running on the phones from many of you. It doesn’t matter if you have the same firmware running on your device or not. All you need to do is make sure you have the SM-G9200 model number, and it is running Android 6.0.1 Marshmallow. The specific build number that Chainfire gives (MMB29K.G9200ZHU2DPC6) is there for you to use as a guideline only. Chainfire states that some Samsung smartphone like the S6 may refuse to boot old images.

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 new CF-Auto-Root file for the Duos version of the S6 smartphone running Android 6.0.1 from here.
  • Download the Samsung USB Drivers for the Samsung Galaxy S6 Duos on the computer from here.

The CF-Auto-Root tool can sometimes need to be updated by Chainfire if a new software update rolls out and updates the Android operating system to newer versions of Android. When that happens, Chainfire relies on you guys to submit the new recovery image files to the official CF-Auto-Root thread made over at the XDA-Developers website. If the files are not updated after a new bootloader is present, it can cause a device not to boot after flashing the rooting package. Moreover, it can cause a device not to flash.

You must have a Windows computer to follow this tutorial or else the Odin flashing application will not work.

You can only follow this guide if you have the Samsung Galaxy S6 smartphone with the SM-G9200 model number. You can find out the model number of your Samsung Galaxy S6 smartphone by tapping on the Settings app > About Device > Model Number. Do not follow this guide unless you have the same model or else you will probably brick the device by flashing the file available in this tutorial.

Rooting the Samsung Galaxy S6 Duos SM-G9200 running the Android 6.0.1 Marshmallow Android version

  1. Enable the USB Debugging Mode on the Samsung Galaxy S6 Duos smartphone so you can connect it to the computer with the USB cable later during the guide.
  2. Extract the rooting package to the desktop of the computer so you can see the rooting exploit and the flashing application.
  3. Install the Samsung USB Drivers on your computer so your device can connect to the computer and be detected by the Odin flashing application.
  4. Boot the Samsung Galaxy S6 Duos in download mode and connect it to the computer with the USB cable.
  5. Wait until you can see the blue or yellow ID: COM port light up from the Odin user interface before you proceed.
  6. Do not make any changes to the default settings coming from your Odin user interface.
  7. Click the AP button and then browse the desktop for the rooting package that will root your S6 Duos smartphone.
  8. Select the Start button and the rooting will now take place.
  9. Look over at the display of your Samsung Galaxy S6 Duos smartphone and then wait until it says that it is installing the SuperSU application, cleaning the cache and then reflashing the stock recovery.
  10. Now quickly look up at the display of your computer and check that you can see a pass message inside a green box that lights up once the rooting is complete.

In conclusion, that is how to root the Samsung Galaxy S6 Duos smartphone running on the Android 6.0.1 Marshmallow operating system. The rooting only takes a few seconds to go from start to finish, so anyone who has not seen the pass box should look for some troubleshooting help within a few minutes. We have some of that in the paragraphs below, but for now, you everyone who did get the rooting to work should see the smartphone automatically reboot and then the SuperSU application will be available from the app drawer. You can enter the Google Play Store via the app on your device and install the root checker app to check that your device is rooted before you attempt to install many of the root requiring applications like the Greenify app we mentioned in the introduction.

Anyone in need of some troubleshooting tips for the Galaxy S6 Duos should make sure that the device got into the recovery mode after the flashing. The developer of the CF-Auto-Root app, Chainfire, publicly states that every device must get into the recovery mode or else the rooting will not have worked. You can press the hardware button combination for the recovery mode and get your S6 Duos handset into recovery after the flashing completes and that should solve your problem. Moreover, anyone else who still need assistance can try installing one of the older versions of the Odin flashing application. The Odin version that comes bundled in your rooting file is the Odin 3.10; however, it comes in several older versions that are also safe to use and could work for you if the Odin 3.10 does not work.
