How to Replace Kinguser/Kingo Superuser with SuperSU via File Manager


For those who are using Kingroot kinguser or Kingoroot superuser in giving root permission on their rooted Android device, today, we will be sharing how you can manually swap or replace it with SuperSU (by Chainfire) using a file manager. But first, we think it is necessary to let you know why you may consider applying steps we are about to share below.

Rooting is one of the necessary procedure for gaining full access and breaking down the barriers to restricted areas on our Android device, giving us the ability to tweak systems files and programs. While not-so-far ago there were "many' rooting apps that lets Android users to easily root their device in one click, the list has grown thin with each introduction of new Android version, leaving us with very few choices, the most popular ones being Kingoroot and Kingroot.

These two apps tends to root many devices and the firms (Chinese) behind these apps are working hard not to be trample upon like others in the past, but then, there was something negative about these two apps, and that is "they have their own separate superuser" in giving root permission. To ordinary (non geeky) users this may not be an issue, but it is to many folks out there especially for those who care about their privacy. It is just unpractical to let some Chinese folks guard the door to ones personal information considering the news that has been flying around for some time now.

"Kingoroot Superuser" and "Kinguser" as superusers of these apps are called, are explicitly different from the common SuperSU developed by Chainfire that many are familiar with. To root a device, Kingoroot and Kingroot needs to establish data connection as all the rooting are carried out in the cloud and are untraceable. The good news is most Android phones can be root by these apps, the bad news is the superuser installed by these two apps are ad-enabled, meaning, once the phone is rooted ads will begin to show on the user phone screen whenever data is on. We found that of Kingoroot to be very aggressive and RAM consuming, and the worst part is the ads cannot be disabled unlesss the phone is unroot. Apart from ads, Kingoroot Superuser also has its own lock screen that battles with system lock screen most of the tine, which can be very frustrating because it cannot be disable as well.

We've once shared an app that can auto swap kingroot kinguser with SuperSU but it works on limited Android device. How about manually replacing kinguser and kingoroot superuser with SuperSU using Android file manager like ES File Explorer? We choose ES File Explorer because it has root explorer built-in. Follow the steps below.

First confirm if the device is rooted by Kingoroot or Kingroot before you proceed.

    This does nothing. No wonder. How should replacing a bckup apk change an installed app, anyway?

  2. Hi, thanks for your comment. Actually, we are not replacing a backup app. We are replacing a system app on a system level by leveraging the root access of the former (unwanted) superuser app.

    Without root this is impossible, but giving that the device already has a full root access, we simply exploit that access to plant a new superuser app that does the same job as the former, while eliminating the former (which is kinguser) in the process.

    We suggest you give it a try.

  3. It says Copy Task Failed. What should i do?

  4. It says copy task failed. What should i do?

  5. Follow the procedures thoroughly.

    Make sure you enable "Root Explorer" and Mount R/W by ticking the "RW" box for both "Path" and "/system", respectively.

    You'll be unable to copy/paste the SuperSU file if you do not do so.

  6. it says su binary occupied, what its that mean?

  7. @Andre Immediately after you successfully swap the SuperSU apk, restart your phone. You can also switch the phone off, remove the battery and insert it back, then turn it on. After doing this, relaunch the SuperSU from your app drawer.

  8. After the process can I safely uninstall kingroot?
