If you are familiar with a desktop operating system such as Ubuntu, then you would know what the root user account is all about. From some Linux operating systems, the root user account is given to you by default when you set up the computer. It’s the same thing as the admin account, and there is nowhere you cannot roam in the file system when using the account.

The Android operating system has the same root user account only Android does not give it to you by default. They block it off by default and have chosen to go down the route of not letting you have it. Just because Android chose to take it away from you doesn’t mean that it doesn’t exist in the Linux kernel and it doesn’t mean there is any way to gain control of it either.

You can get in control of the root user account on the Samsung Galaxy A9 SM-A9000 smartphone by using Chainfire’s one-click rooting method. Instead of logging in as the root user like you do from most Linux distributions, the CF-Auto-Root tool enabled SuperSU on the smartphone. The SuperSU then chooses to grant the root permission to the apps that you want to have root after you install them. The rest of the time the SuperSU blocks the root access from the other apps you install or from apps that don’t demand it before they will run. You can also manage what apps you have chosen into grant root access after the fact of originally granting them the rooting permissions, so no choice you make needs to be a permanent one.

REQUIREMENTS

• You need to have the Samsung Galaxy A9 smartphone that comes with the SM-A9000 model number to use this guide. Any of the other model numbered variants of the Samsung Galaxy A9 smartphone get bricked if you flash the version of the CF-Auto-Root rooting file found in this guide because the particular rooting tool found in this guide is always made for one model number each.
• You do need to run the Odin flashing tool that flashes the rooting tool to your device on a Windows operating system. The Samsung developers did not make the Odin flashing tool to work on any of the other computer operating systems. Further, attempting to run Odin from a virtual machine is not a great idea either; it has been known not to work and even causes problems.

BEFORE WE BEGIN

• You need to have the Samsung USB Drivers installed on the computer so install them if the computer does not have them installed already. You do not need to install them twice and if you installed them anytime over the lats few years out should be fine to keep the same file without the need of updating it.
• You need to unlock the Developer Options menu on the Samsung Galaxy A9 SM-A9000 smartphone and then enable the USB Debugging Mode so the Android software running on the smartphone can get the necessary changes made to it so that it gets rooted.
