Chainfire has created yet another one-click rooting tool version of the CF-Auto-Root and made it available for the Samsung Galaxy Note 4 S-LTE SM-N916L smartphones running on Android 6.0.1 Marshmallow software updates. Since Android 5.1 Lollipop, the CF-Auto-Root tools have been what is called a systemless root where they no longer need to pass through the system partition.

Most people already know of the system partition as the place where manufacturers and phone carrier networks tuck away their apps so people cannot remove them. That was the area that CF-Auto-Rot used to need to access before it could work. Nowadays things are much cleaner, and the rooting tool does not need to go anywhere near there.

The CF-Auto-Root tool is flashed with the Odin flashing tool which is the same flashing tool that many Samsung device owners use to flash a stock ROM. Chainfire’s goal was to give people an easy way to root and also a way people can root without having to install a custom recovery. While most people enjoy installing a custom recovery and then flashing the SuperSU to get root access, not everyone wants to take away the stock recovery—even Chainfire sometimes. The CF-Auto-Root tool is a solution for that.

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.

Details We Should Know

  • There might be some more software updates that roll out over the air for the Samsung Galaxy Note 4 S-LTE SM-N916L smartphone when it is running on the Android 6.0.1 Marshmallow software updates. These updates should not stop the CF-Auto-Root tool from working because usually, only the new version of Android updates are the ones that can create problems with new bootloaders being available. That said, if you do find your Samsung Galaxy Note 4 smartphone is not booting after the rooting file flashing then you need to let Chainfire know about it by leaving a message with the new recovery image found in the firmware creating the problems to the CF-Auto-Root tool thread made over at the XDA-Developers website.
  • Chainfire had the MMB29K.N916LKLU2DPD6 firmware build number running on Samsung Galaxy Note 4 S-LTE SM-N916L when he developed the CF-Auto-Root tool that is available in this guide. You do not need to be running on the same firmware build number that he was when you follow this guide. You can run on any firmware. All you need is to be running on the Android 6.0.1 Marshmallow software updates and to have the correct model number versions of the Samsung Galaxy Note 4 smartphone (SM-N916L).

Files We Need

  • Download the CF-Auto-Root tool for the Samsung Galaxy Note 4 S-LTE SM-N916L running on Android 6.0.1 Marshmallow update.

  5. Run the Samsung USB Drivers on the computer so the smartphone can be picked up by the flashing tool.
  6. Boot the Samsung Galaxy Note 4 S-LTE SM-N916L smartphone into the download mode and then connect it to the computer with the USB cable.
  7. Check Odin shows a color coming from the ID: COM and install the Samsung USB Drivers again if it doesn’t.

In conclusion, that is how to root the Samsung Galaxy Note 4 S-LTE SM-N916L phones running on the Android 6.0.1 Marshmallow software updates. The guide makes use of the CF-Auto-Root tool by Chainfire, and the smartphone now has the SuperSU app available from the app drawer. Even though this method is called the systemless root method, it still works the same way. SuperSU is already operating and doesn’t require you to do anything to get it working. Just open the Google Play Store application on the phone and then start installing the apps that require root access before they can run.You can check out some of the best root apps for Android if you need some ideas before hitting up the Google Play Store. You need to go into the Play Store knowing the names of the apps that you want to search for because there is no dedicated area showing you the root apps.
