How to Unroot Basically Any Android Device with SuperSU
SuperSU is easily the most popular and robust root management app available on Android. If you’re running a rooted device, there’s a very high chance that you’re using SuperSU to manage which apps get superuser access. It’s also the smartest and easiest way to quickly unroot your Android device, because the entire process is done within the app directly on the phone.
To fully unroot the device, the first thing you’ll want to do is jump into the SuperSU app, which is found in the app drawer.
Once opened, swipe over or tap the Settings tab and scroll towards the bottom till you see the “Cleanup” section. Tap the “Full unroot” option.
This will present a dialog box with what to expect from the unroot process and ask if you’d like to continue. If you’re on a device with the traditional rooting method—generally Lollipop or older—then this is the first and only step for you. Hitting continue will unroot the device, and you’ll need to reboot to finish the process.
If you’re on a device that was rooted with the systemless root method in Marshmallow, tapping the “Continue” option will open another dialog that asks if you’d like to restore the stock boot image, noting that this is required for OTA (over-the-air) updates. If you’re hoping to download the latest Android update when it drops, or if you’re getting rid of the device, then I would suggest tapping “Yes” here. If those options don’t apply to your situation, it’s probably fine to just leave the modified boot image by hitting “No.”
The following screen may ask if you’d like to restore the stock recovery image. If you’re running a custom recovery (which is likely) and you want to pull an OTA update, this option is necessary—tap “Yes” to continue. If you plan on re-rooting in the future or want to continue using your custom recovery (say, for nandroid backups), then hit “No” here. There’s a chance that this option may not show up, in which case you’ll have to manually flash the stock recovery. There are instructions on how to do this in the manual section below.
After that, SuperSU will remove itself and clean up the installation. The entire process will only take a few seconds, and then the device will reboot. Once it’s finished, it should be completely unrooted and, depending on which options were selected during the unroot process, back in a completely stock form.
