We all know that applications are the cornerstone of our mobile operating systems regardless of what it is. Android is only popular because it has a great App Store; iOS is only popular because of the App Store and Windows have historically struggled in the mobile consumer technology field because they didn’t develop the Windows App Store nearly quick enough.

Out of the millions of apps that are available out there for you to install on Android online, there is a percentage of them that do not run unless they sense that you have something called root access. Having root access on Android is the shorter way of saying that you have access to the root user account which always exists in Android but is taken away, so we do not get access to it by default. The root user account to Linux is what the administrator’s account is to a Windows operating system. Both make you the person who has full control and the final say over what is installed and what is deleted. You could easily argue that there is not much difference between Windows and Android and we are hard done by for not getting root access by default. Regardless, that is the way Android decided to release it to us, so we do not have much choice but to deal with it and do a little bit of work to get root access instead.

The amount of work that is required in becoming the root user varies depending on the way that you choose or need to go about it. Sometimes you get a choice between a few unique methods and other times you need to do whatever is available and roll with just the one option.

With Samsung devices, there are usually two choices a person can make for getting the root access on the device. One of them is getting a custom recovery installed, and the other is using a one-click rooting tool such as the CF-Auto-Root tool. The CF-Auto-Root tool is great if you just want to be installing the root applications because it does not change anything to your device at all apart from installing and enabling the SuperSU which then grants the root access to the apps.


  • Chainfire was running on the MMB29K.J710KKKU1APG3 firmware build number when the version of the CF-Auto-Root tool that is found in this guide was developed. It does not matter if you are running on that same firmware build number or not because he is not a suggesting that you do need to be running on the same firmware build number as him. All it means it that you can use it as an indicator if the time ever comes that it is relevant information for you down the road.
  • There is an official CF-Auto-Root tool thread made at the XDA-Developers website that people can post comments on if they ever want to learn something or even request for Chainfire to make a new rooting method for a device in the Samsung range that does not yet have one—like some of this year’s versions of the Galaxy J and A series handsets. The same CF-Auto-Root tool thread is also where people post comments alerting Chainfire to the fact that some of the current rooting tools need updating. You know one needs updating if you flash the right file and it causes the device not to boot up afterward. These are often when a new bootloader has arrived with a new Android version. Before he can update the files, so they begin to work again, people need to leave a message that contains the new recovery images from the firmware because he uses those to update the rooting files.
  • You need to have a computer that is running on the Windows operating system to use this guide. Any other operating system is not able to run the Odin flashing tool because it has been developed to run on Windows operating systems only. What’s more, it is not recommended that you try running Odin from a virtual machine as an attempt of a clever workaround from another operating system as that is not usually enough to make it work and it can also create problems.
  • You need to have the Samsung Galaxy J7 smartphone that comes with the SM J710K model number to use this guide. The CF-Auto-Root tool files are only ever made for one model number each. Moreover, flashing the wrong version on the wrong model often results in that handset the being bricked until you flash the right stock ROM back on the device.

In conclusion, that is how to root Samsung Galaxy J7 SM J710K smartphone running on the Android 6.0.1 Marshmallow software updates by flashing the CF-Auto-Root tool by Chainfire. Whenever you get a version of the CF-Auto-Root tool that is based on the Android 6.0.1 Marshmallow software updates, it is always the systemless version that does not go through the system partition. Everything else remains the same, and you get to see the SuperSU application from the app drawer. That SuperSU is installed and enabled already so you do not have to do anything if you want to start installing root apps apart from installing the apps themselves. Most of those root apps are available from the Google Play Store and the ones that aren’t can always be found by doing a standard Google search instead.
