You might have heard about this thing called the root user on Android and decided that you wanted in. If that time is now and you own the Samsung Galaxy J7 smartphone with the SM-J700F model number when it is running on the Android 6.0.1 Marshmallow update, then you are in luck. Chainfire has you sorted out with a version of the SuperSU app that can be successfully installed and enabled just by flashing it from a custom recovery image.
Here is what you need to root Samsung Galaxy J7 SM-J700F running on Android 6.0.1 Marshmallow software updates by flashing Chainfire’s SuperSU app:
- You need to have a custom recovery installed on the Samsung Galaxy J7 SM-J700F smartphone  before you can follow this guide.
BEFORE WE BEGIN
- You can take an NANDroid Backup from inside the custom recovery partition when you boot into the Recovery Mode during the guide to make a backup of the data. Apps like Titanium Backup are still out of your reach until you complete the guide below, but the NANDroid Backup is just as good, and since you have the custom recovery installed already you might as well make use of it. Anyone who isn’t fond of taking the NANDroid Backup can try installing the Helium app from Google Play and backing up most of the data that way.

Just head to the Play Store—or any of the sources online where your root apps exist—and download them. Once you open the root app, you get a message from SuperSU asking whether you would like to grant the app root access which in turn allows it to work.
