In this guide we will see how to get root permissions on the Galaxy A3 through the SuperSU application. If you are ready, let's see how to root the Samsung Galaxy A3 (2017) running Android 6.0 Marshmallow through this quick and easy guide.


The Samsung Galaxy A3 (2017) is the smallest variant of a very interesting series. To better configure the device and have more functions available, the best option is to root.



Once you have rooted permissions on the Galaxy A3 2017, you will have access to hundreds of applications that need root access to work completely and are available directly on the Play Store.

These applications increase functionality and in some cases even performance. The procedure for rooting is quite easy. It is necessary, however, to have TWRP custom recovery installed before starting with this guide.


If you have not yet installed the custom recovery on your Galaxy A3, I recommend you read our previous post: How to install TWRP on the Galaxy A3. Once the custom recovery is installed, SuperSU installation will be very easy.

Be careful regarding the warranty of your smartphone. Guidesmartphone is not responsible for any damage done to your smartphone by using this guide.

Before starting with the tutorial, I recommend that you back up your Galaxy A3 2017 in case something goes wrong. If you don't know how to do it, here you can find how to backup to your Galaxy A3.


From this page download and install the drivers for your device. On this other page you learn how to activate USB debugging and here instead how to enable OEM. I recommend that you unlock the bootloader.



Download: SuperSU Root (SuperSU-v2.79-201612051815.zip) for the Samsung Galaxy A3 (2017) on your computer or directly in the memory of your phone.

Download and transfer the SuperSU file to the internal memory of the device, now boot the device through the TWRP custom recovery, holding the Volume Up + Power buttons together.


Once in the menu go to install and select the file you just downloaded, then click on install and flash the SuperSU file that you transferred in the previous step.


Once SuperSU is installed you are done. Restart the device. Your Samsung Galaxy A3 2017 has received root permissions.

Now you can install all those applications that were previously unusable because the device was not rooted.
