Root is referring to the name of the account that most Linux kernels have as a part of the operating system. The desktop versions of Linux commonly known as distributions give the root user account to the first person who sets up the computer much the same way the first person to set up a Windows operating system gets control of the admin account.
The Android operating system doesn’t do things like the Linux desktop versions of the Linux kernel does things. Nobody gets to use the root user account when they set up a mobile device for the first time if it is running Android. In fact, no matter what you try to do there is no way of getting on control of the root user account unless you get help from an outside source.
These are called rooting tools that third-party developers create that help people like you get root access on a device. Sometimes the root tools are one-click rooting tools and other times you can flash programs like SUperSu from custom recovery images to get the root access instead. It just depends on what is available and what your preference is when you go to root it.
The people who want to be installing custom ROMs and custom kernels typically try unlocking the bootloader, installing a custom recovery and then getting the root access by flashing the SuperSU if that kind of rooting method is available. Everyone else who just wants to install root applications and has no reason to change the stock recovery for a custom recovery can try using one-click rooting tools instead.
The most popular one-click rooting tool for Samsung smartphones and tablets is the CF-Auto-Root tool. An Odin flashable rooting tool, CF-Auto-Root installs and enabled the SuperSU just like what happens when people flash SuperSU manually fro ma custom recovery. The difference is that it doesn’t require any work from your end and it doesn’t leave your device with a custom recovery image installed.
Regardless of your choice in rooting method, you can always install the same amount of root applications. The only difference is that you cannot always install custom ROMs. That means any of the root apps that you already know you want to install are going to be available to you no matter what.
Details We Should Know
- Chainfire was working with the MMB29K.J700FXXU2BPH3 firmware build number running on the Samsung Galaxy J7 SM-J700F smartphone when he developed the versions of the CF-Auto-root tool file that is available for use in this guide. By him telling you that it is not suggesting that you need to be running on the same firmware build number when you try rooting using the same file. He is just giving the firmware information in case it becomes relevant information to know in the future like when you want to use it as an indicator.
- You should let Chainfire know if your device is not booting up after flashing the rooting file because those are the times when the rooting files need updating. Before he can do anything about it, he needs the recovery image files found in the firmware that is running on your device. He uses that file to update the rooting file so that it starts working again. That is one of the common issues that arises when a new bootloader is present in a new firmware. Send your messages into the official CF-Auto-root tool thread on the XDA-Developers website and make sure it includes the recovery image file from the firmware that is running on the smartphone.
- You need to have the Samsung Galaxy J7 smartphone that comes with the SM-J700F model number to use this guide. Any of the other model numbers that might be available for the Samsung Galaxy J7 smartphone will be bricked if you flash the version of the rooting file that is found in this guide because they get developed for model numbers, and each model number typically needs an individual file.
- You need to have a computer that operates on a version of the Windows operating system to use this guide. Any of the other operating systems cannot run the Odin flashing tool, and since the rooting file is only flashable within Odin, you know that there is no other way that it can work.

In conclusion, that is how to root the Samsung Galaxy J7 SM-J700F smartphones using the CF-Auto-Root tool when they are running on the Android 6.0.1 Marshmallow software updates. The version of the CF-Auto-Root tool is likely going to need to be updated again when the Android 7.1 Nougat rolls out to the smartphone, but for now, you have the systemless root version of the tool that allows you to unroot the device just by taking a hard reset from within the Recovery Mode. Furthermore, you can fully unroot by using the button available under the same name from inside the SUperSu app or even by flashing the right stock ROM for it. You can find most of the stock ROMs from the Sam Mobile website as it is still the most reliable source for Android ROMs today. The SUperSu app is available from the app drawer hidden amongst your regular apps now when the smartphone reboots. You do not need to do anything from inside it before the root apps can run on the smartphone, however. Just install the root apps and then SuperSu prompts you with a message asking you to confirm that you do want to grant the rooting rights to it over the operating system. It only ever asks the one time and then it will not ask again until you install another new app that has not had the rooting permissions confirmed yet.
