Android rooting has become one of the most popular Android-related technical tasks by now. Although Android is officially an Open- Souce platform, it behaves really tough on our Android smartphones as it has been designed to behave so by the device manufacturers. That is why Android smartphone users prefer Android rooting. If you have an idea to root your Android device and you are a fresher to the subject, reading this would be really beneficial to you as this is going to describe all the important things related to Android rooting.


Android

Android was launched in 2008 and it has been about 10 years after the initial release. As of now, it is the most popular mobile operating system in the world. The majority of the available smartphones are powered by Android. Google, the developers of Android, launched Android as an open-source platform which means the source code of the Android system is available to study and modify under the license from the copyright holder. Also, modified versions of the platform can be distributed as a newer version of the official builds.


Android Rooting

In simple words, Android rooting is the mechanism that is used to access the system files of the Android system. Technically, Android is based on a modified version of the Linux kernel and uses a single root for whole the system. It means no separate file structure of each partition and every partition in Android consumes the common file structure. In case you need to change the system files, you need to access root / system files in the system partition under Root which is indicated by (/). But, you can not access them as your device manufacturers have denied your access to root files. All the important files and command related to the Andriod framework and UI customizations have been placed there. As third-party access might be harmful to them, your device manufacturer has denied the access by imposing virtual barrier you and those files. On the other hand, UI customization is one of major fact which determine the attraction of the customer to each model. Third-party customizations on it may reduce the attraction to stock UI.


How To Root Android

There are two technical methods to root an Android smartphone. Although the methods are different, the final result is the same. As mentioned above, Android is based on a modified Linux kernel and Linux uses a command named Su (Substitute user) to change the administrative privilege on the Linux system. This command is called as superuser command or switch user command. Generally, your device manufacturer is the administrator of your device and you can only reach some extent of the Android file structure. When you root your Android device, the specific rooting utility executes the Su command on your Android device. It changes your ordinary ownership to the root user which means grant you administrative privilages to access all the files and command in your Android device.

Rooting Methods

One-Click Rooting Tools - One-click rooting tools are based on Android vulnerabilities. It means One-click rooting tools have been designed to use security holes in the Android kernel and access to system files to execute the Su binary files. Superuser.APK and Su binary file plays a special role in Android rooting as your device cannot gain root access without the Su binary. When an app asks for permission to access the system files and run as a system file, the Su binary is called and asks for permission. Then, the Su binary checks the SuperSU.APK to determine if the root access has already been granted or not. If not, it prompts you to get your permission to grant root access for the respective app. The prompt window is the interface of the Su binary and it may differ from each rooting tool. Also, a common root management tool such as SuperSU can be used to manage root access.


Recovery Method - Some of the rooting utilities have been designed including both Su binary file and root access management application. MagiskSu and SuperSU are the best examples. Android users can gain root access by flashing the Zip file of each rooting solution in custom recovery mode and manage it using the correspondent root access management tool. In this method, the stock firmware is updated applying the necessary changes on the stock firmware to run an app as a root app. Technically, the stock recovery mode on your device does not accept any unofficial updates and that is why you need to flash Custom recovery to install those updates includes in rooting solutions such as MagiskSu and SuperSU
