How to Completely Remove Root, SuperUser and Related Files

Getting your Android device rooted with KingoRoot (or any other root tools) surely has its benefits, and yet with risks and consequences as well. One of them is failing to update through OTA. Rooting, in fact, is a process of tampering your Android system, which will lead to OTA update failure. Because when you try to update your system via OTA, it will first check your system and make sure it hasn't been altered at all.

After rooting, what has been added to your Android System?

KingoRoot, along with any other one-click root tools, are all exploit-based. It means that your device is being rooted by them exploit certain system vulnerabilities. After having accessed to your system partition, certain su binary files and superuser app will be placed in it. Normally, they will be placed in:

• /system/bin : su binary
• /system/xbin: tmpsu, daemonsu (may not be necessary)
• /system/sbin: su binary (may not be necessary)
• /system/app: superuser.apk or the apk of any other management tool

It is not necessarily in all of these directories. It depends on the tool you have used to root your device. So basically, if you want to update your device via OTA, you may need to completely remove the residual files (including all su binary files and superuser apk). Or you just want to have a clean slate.

There are two ways to completely remove root-related files and all.
