All the Android users are talking about Android rooting and most of Android users try to root their Android devices. Because Android rooting allows users to customize their Android smartphones in the way they want. None of the users wants to stay behind the software restrictions that come from device manufacturers and network carriers when there are lots of interesting things are waiting out of restrictions. Assuming you are aware of root permission , I am going to talk about Su command which plays an essential role in Android rooting.

In technical terms, executing Su command is Android rooting and Literally, it can be explained as getting permission to access the system files of an Android device. Technically, Android-based on a modified version of Linux kernel and the "Su" command is used in Linux to change the user who already logged in to the system without forcing him to logout first. The Su command can be used to change ownership of any session's user. But, mostly the command is used to change the ordinary users' ownership to root user. In Linux or other Unix-like operating systems, "Root" is the user name or account that has access to all the files and command by default. It is called root user, superuser or root account occasionally. When it comes to Android which is based on Linux, uses the same Linux file structure which begins from the single root directory. After accessing the root directory or getting root access, you can access all the files and commands in your Android system. This is the basic Android rooting mechanism.

There are two universal ways to execute the Su binary on an Android smartphone. The first method is executing Su binary on your Android device using Android exploits and transfer the root ownership from your device manufacturer to yourself. One-click root app developers, follow this mechanism to develop one-click rooting tools and you can use a compatible one-click rooting tool on your device to have root access. The second method is executing a modified firmware file along with  Su binary via custom recovery mode. Both methods install Superuser.Apk file on your device to prompt you when an app requests root permission to work.

Final Word

So, you may now understand that there is no Android rooting without proper Su binary installation. Actually, you do need complete knowledge about the mechanism underlying the rooting since your rooting solution does all the thing for you.But, it is advisable to have idea what is going on when you root your Android device.
