root Android


You must be already searching for a successful rooting solution if you have become unsatisfied with stock Android features. Frankly, Android itself can provide lots of features than on smartphones and tablets. Therefore, most of Android users try to have the full potential of Android through the Android rooting. As far as I know, it is hard to find someone who is not aware of Android rooting as of now. However, let's beginning the topic from the Android root

Android Root


The key purpose of Android rooting is allowing end users to acess the system files of an Android device. As you know, In Windows you can acess your programme files and change them when you want. But Android smartphones do not allow Android users to acess their system files that much easy. You need to get the permission from your device manufacturer and it is not granted by default. The Android system files contain the whole Android framework and system apps that are responsible for the proper functioning of the device. 

Android File System Structure 


In Windows, you can find each root directory for each partition and specific root directory contains specific files and folders for the specific partition. But, the Android file system is based on the Linux file system and it only contains a single root directory in which all Physical disks and partitions contain. You cannot find a drive letter for Android root directory as it is symbolized by a forward slash (/). So, as you are trying to acess the system partition under Android root directory, it is called as getting root access. Officially, you are not allowed to acess system partitions and directories in Android as Windows does.


What You Can Do After Getting Root Access


Basically system partition contains kernel and the ramdisk along with system apps, Android framework and Android UI. After getting root acess you can change them using apps and files to have different appearance and functionality on your device. Actually, you cannot change anything as simple as tapping on your device home screen. Each change needs a specific procedure. Let's consider installing a custom recovery on your device using a custom recovery manager app

Recovery is one of the available Android partitions. The purpose of the recovery partition is to provide options that help users to repair the device when software issues occur, install official OS updates manually and delete users data and files. Technically, stock recovery has only a few capabilities. That is why custom recovery comes to the front. A custom recovery can offer advanced options than stock recovery options. As custom recovery app come from third-parties and its need to acess the root directory. Then, it can install the custom recovery image where the stock recovery image has been located to be installed. So, you need root your device first to install the recovery manager app


How To Root Android



Technically, there are three way to flash your Android smartphone. All the rooting techniques do the thing although the process is different. You can get to know what are they in a simple manner after reading  the next chapter


  • Android Exploit Method - Exploit method contains three steps as Exploiting Android vulnerability > Installing Su binary file in Android system partition  >  Installing Superuser management app. Technically, all the one-click rooting tools use Android Exploit Method and the above three steps are the life cycle of a one-click rooting tool

  • Flashing Su Binary In Custom Recovery - This method is frequently used among Advanced Android users and you need to install the relavant custom recovery on your Android device using fastboot and ADB commands through the computer first. Then, you need to flash the Su binary file on your device after booting it to custom recovery mode. Generally, the Su binary file is not available solely. It comes with a root acess management app. Magisk, SuperSU are the best examples

  • Flashing Su Binary In Stock Recovery - This method only can be applied for Smasung Galaxy users. Samsung offers Samsung Odin flashing utility software for Samsung Galaxy flashing purposes along with the capability of flashing the root binary. As other root binary flashing methods such as Magisk, Odin root does not require a custom recovery. You can directly flash the Odin flashable root package in stock recovery on your device through the Samsung Odin application.

Note: Android exploit method does not require you to unlock the bootloader of your device as it does not flash any modified partitions on your device place the Su binary file. But, the next two methods need your Android device with the unlocked bootloader to flash Su binary file. Because  both methods flashes modify partitions or patch the existing partition in order to install the Su binary



Final Word

This is the summarized mechanism of the whole Android rooting process. I hope now you have a better idea about rooting than previous after reading this piece of article.
