If you want to do things that alter the Android software or operating system or require you to have full read permissions, then you need to install root apps.

The Google Play Store plays host to two varieties of applications. One of them is the kind of apps that everyone can install, and the other are called root applications. The root apps are the apps that are restricted to the people who have root access on the device—and that is what people do when they follow a guide like this one below.

A root app requires rooting permissions before it can run. It doesn’t matter what rooting tools you use to get the job done. As long as you end up with the mobile device rooted then it can run all of the same root apps.

There are thousands of reasons why people choose to have a device with root access and chances are your reason is different to the following individuals who use the same guide after you use it. However, there are also many common reasons and root apps that people have in common that they always love to install.

If you are choosing to root the Android operating system for practical purposes, then you might want to look for an app that can backup all of your apps easily since that was something that was impossible to do without root access. The Titanium Backup app is perfect for that. If you are a gamer and want to know how to enhance your gaming, then you should check out something like the Chainfire 3D app or the GLTools app instead. No matter what you are interested in doing with your rooted Android, there are plenty if apps out there to help you enjoy Android more than you were before.


  • Chainfire had the MMB29K.A800FXXU1BPF5 firmware build number on his Samsung Galaxy A8 SM-A800F smartphone running when he developed the version of the rooting tool that is available in this guide. It doesn’t mean that is the same version that you need to be running. The fact of the matter is that there might be many different firmware versions that are part of the Android 6.0.1 update. As long as you are running the Android 6.0.1 Marshmallow software updates, then it shouldn’t matter when firmware build number as running.
  • Some software updates bring new bootloaders with them, and the new bootloaders are what can cause the CF-Auto-Root tool to stop working until Chainfire updates the files, so they start working again. If your device does not boot after the flashing or the flashing just doesn’t work you can let Chainfire know about it by leaving a message with the recovery image file from the problematic firmware to the CF-Auto-Root tool thread that is made over at the XDA-Developers web forum.
