Root is the nervous system of the phone; it allows access to and modification of almost all the files on your Android device. These are probably things phone manufacturers do not want you to modify or touch because they could affect phone stability or be exploited by hackers. Root is the only superuser in the system, with all system permissions, such as starting or stopping a process, deleting or adding users, enabling or disabling hardware, etc. In short, root allows you to use your phone as you wish; you can directly delete any bothersome system programs without having to endure them.
Why obtain root access?
The main reason to use root access is that many things on our phones are restricted. By obtaining root access, we can do things we are otherwise restricted from doing. For example, Google prevents us from seeing many free or paid apps in the market, but with root access, we can enter the Market and view them.Many friends can only view but cannot download, and they cannot bind Gmail. We can modify the host to fix this for them; for some customized phones with unwanted pre-installed software, we can use RE Manager to handle it. But all of this requires Android 4.0 root permissions (since root permissions grant ultimate control over the system, it's convenient to delete or modify system components. For users, only by obtaining root permissions can we freely 'repackage' our beloved device and experience the advantages of new software versions). After obtaining root, we can back up the system, use more advanced programs, modify system programs via RE Manager, and install programs on the SD card. \ Standard One-Click Root Tutorial \ Although the rooting method differs for each model, the general steps are quite similar. So what should we pay attention to when rooting? First, for users of Chinese phones, once rooted, the phone is no longer covered by warranty. However, the editor believes that as long as it is not hardware damage, everything else can be fixed by yourself. \ Generally, the rooting steps involve turning off the phone, restarting it into a specific mode, and then performing operations on a computer, which does not take too long. \ After rooting, you will find an additional application in the app list, such as Superuser or LBE, indicating that the phone has been successfully rooted. At this point, you have the highest permissions on your phone. To better manage the phone, you can download some phone management software, like RE Manager, and then delete unnecessary system apps, improving the phone's running speed to a new level.
\ Summary: I strongly recommend that friends who want to flash or root their phones search for instructions on their phone's official website, as this has a higher success rate and is safer!
