If you own a Samsung device, then chances are you are in luck of obtaining an easy root method. Whether it be using a one-click rooting tool like Chainfire’s CF-Auto-Root or flashing a SuperSU package from a custom recovery image, Chainfire has got you covered nine times out of ten.
If you are into becoming the root user on Android, then you would know who Chainfire is already, and you would know that he is superb at what he does. Rooting is not the only thing he does in life, however, and sometimes he does not create CF-Auto-Root tool versions as quickly as he probably could. The Samsung Galaxy J7 smartphone with the SM-J700F model number is one of those devices. You need not worry, though, because there is a custom recovery image (TWRP) available and with it, you can become the root user by flashing the right version of SuperSU.
Here is everything you need to install TWRP Recovery on Samsung Galaxy J7 SM-J700F smartphone so you can flash ROMs or even become the root user:
- The following guide is only made for the Samsung Galaxy J7 smartphone that comes with the SM-J700F model number. You can find out the model number of your Galaxy J7 smartphone by tapping on the Settings app > About Device and then looking under the subheading of Model Number. Attempting to flash the version of TWRP that is available in this guide on any other device probably bricks that device.
- You need to have a computer that is running on a version of the Windows operating system to use this guide since the Odin flashing tool only runs on Windows, and that is the tool we are using to flash the custom recovery image.
BEFORE WE BEGIN
- Make sure you unlock the Developer options  menu on the Samsung Galaxy J7 smartphone and then enable the USB debugging  from within the Developer options menu. Only then are you able to make changes to the Android software which is what is going to be happening when you follow this guide and swap recovery partitions.
- Install the Samsung USB Drivers on the PC  before getting started with the guide so that your Samsung Galaxy J7 smartphone can be detected by the Odin flashing tool and allow for the flashing of the custom recovery.
