Rooting the Samsung Galaxy A3 smartphone is the only way for you to gain full control over the operating system. Google and Android take away the root user account from you so that apps cannot move around but that also stops your ability to get around too.

There are heaps of apps out there from the Google Play Store and other sources online that need you to have root access to the Android operating system before they can run.

One of those root apps that you might be interested in checking out is the Titanium backup app. Constantly a personal favorite of my own, the Titanium Backup app gives you a chance to backup every app that is running on the device as it stands today and when you sought through the list, you will likely come across some that you never even know that your device had. Moreover, Titanium Backup is also perfect for removing any app that is on the device. Because of the root access power that Titanium backup app, that means you can uninstall anything from the system partition and that means removing the bloatware or system apps.


  • Chainfire had the MMB29K.A310N0KOU1BPFA firmware build number running on his Samsung Galaxy A3 SM-A310N0 smartphone when he created the working method that is available in this guide. He doesn’t show that information because you need to be running it too. He just gives that information so you can use it later as an indicator of you need it. You can follow this guide and use the file in this guide if you have the right model number, and it is running on the Android 6.0.1 Marshmallow software updates.
  • There are times when the CF-Auto-Root tools can stop working temporarily. These times are usually when a new bootloader is present. The new bootloader usually only come in new versions of Android which means that you shouldn’t have those problems in our guides that are only written for one Android version (Android 6.0.1 Marshmallow). Still, if you think a file is not working as it should, you can let Chainfire know about it by leaving a message on the CF-Auto-Root tool thread made at the DA-Developers website. You need to leave the recovery image file from the new firmware that is running on your device in the message so he can use it to update the rooting file so that it starts working again.
