The root access on Android is referring to the root user account that is always blocked off by default. Anyone who knows Linux distributions and has set up one of them for the first time will already know all about the root user account because that account is assigned to the first person to set up the computer. Another way people refer to the root user account on Linux is the superuser.

The root user account is essential for Linux operating systems on computers because that is the account that has all of the root privileges over the operating system. The root privileges are referring to the chance to access all files and run all commands. The root user account has the power to modify the system in any way the person in control of the root privileges should desire as well as the ability to grant or revoke other accounts ability to modify, read and execute files and directories that are available on the operating system.

Nobody knows exactly why the Android developers have chosen not to let people set up the Android account as the root user, but it is widely believed to be because of malware disguised as apps. The Google Play Store is a trustworthy place in general, but there are always occasional apps that make it onto the Play Store and can be there for weeks until they are identified and removed. If a root user installs malware from the Play Store, then that malware can move out of its prison that it would’ve otherwise been trapped in if the person using the device was not in control of the root user account. In fairness, the same problem is there on Linux; the root user account should never install malware on a computer for the same reason. However, Android seem to think that either the chances are higher to install malware from the mobile version since most things you can do revolve around installing apps first or because they own the Google Play Store and don’t want to develop a bad name.


  • Chainfire had the MMB29M.P555SKSU1BPF1 firmware build number on the Samsung Galaxy Tab A SM-P555S when the rooting file available in this guide was a developed.

In conclusion, that is how to root the Samsung Galaxy Tab A SM-P555S tablet running on the Android 6.0.1 Marshmallow software updates by flashing the CF-Auto-Root tool by Chainfire. The one-click rooting tool that Chainfire calls CF-Auto-Root has just finished installing the SuperSU on the tablet, and it is enabled and ready to start granting the root permissions to nay of the apps that request it. You can start installing the root apps that you wanted to try right away.

The SuperSU keeps your device completely safe all of the time until it hands the responsibility over to you when an app you have downloaded request the rooting permissions. Instead of the SuperSU automatically allowing everything root access it prompts you with a message letting you know what applications is asking to get the root access and then you need to be consciously aware of the root apps that you are granting the rooting permissions to because the SuperSU does do not try to detect the malware and give you a warning of what not to let through. While that sounds daunting to some, the reality is that everybody who knows apps already knows if they are downloading a trusted app or not just by looking at it, so there is no reason not be installing malware. However, the good news is that if you do install malware by accident the SuperSU blocks it automatically and then you just need to deny granting it root access when the pop up message comes up on the device’s display and then delete the app you wish that you hadn’t of installed on the device.
