These are the guidelines to root Samsung Galaxy A7 SM-A710 using your custom recovery and the SuperSU app. That same SuperSU app is made by Chainfire and is going to be granting your Samsung Galaxy A7 smartphone the rooting permissions you need when installing those awesome root-requiring apps.

REQUIREMENTS

• You must have a custom recovery installed on the Samsung Galaxy A7 smartphone before you can follow this guide. You can learn how to install TWRP Recovery on the SM-A710M, SM-A710Y, SM-A710FD, SM-A710F.

BEFORE WE BEGIN

• Download the Samsung USB Drivers for the Samsung Galaxy A7 smartphone and install them on the Windows computer before getting stuck into the guide after the jump. It’s the USB Drivers that are going to help your Windows operating system and the Odin flashing tool pick up your device.
• Rooting the Samsung Galaxy A7 smartphone does void the warranty. Any Samsung device that comes with Knox will be tripped during this guide. You can install unroot and flash a stock recovery on the device, but it will not be under warranty.
