Hello, yesterday I bought a second-hand Samsung Galaxy S6 phone, Android 5.1 OS, but I found it seems to be be already rooted before. How can I be sure? When I download apps that require root they don't work. I wan to change privileges on this rooted phone Or how can I re-root? Thanks!

If it is already rooted, you might just need to re-install SuperUser or SuperSU. It depends on if the kernel has been replaced. If the kernel isn't rooted, you can use Odin to install a rooted kernel.

Root Checker Basic is a free app from the Play Store or app market that will tell you whether or not the phone has root access. Another simple way to find out is to download and install a "terminal" client on the phone. If the phone was not rooted, then here is a great guide on how to root s6. It's one of the best rooting app for newbies.

Thanks, I've used Root Checker to check if my phone was rooted, it seems that my phone was not rooted, so, how can I root my phone?

This will only work if the app can request SU/sudo permissions. If there is no SuperUser/SuperSU installed, it has no way to ask. Rooting is actually a two-part process.

 

The first part is a kernel modification. The kernel is the core of the phone. It has the final say when it comes to permissions. The first part of the rooting process will change a bit of the code in the kernel (and void your warranty) by telling it to allow the user to have administrative level access. This will allow the user to modify the operating system of the phone, which is part two.

 

The second part is the installation of the SU binary. The SU binary is what delegates access to apps from the kernel. It is essentially a gatekeeper.

 

I have had a Note 4 survive an OTA update but lose root. I thought I would have to patch the kernel again, as all my root apps said I no longer had root. Root Checker even stated I had no root. I noticed I no longer had SuperSU either. I reinstalled that from the Play Store, and voila, my apps all started working again.

 

Suunlly, I highly suggest installing SuperUser/SuperSU first to determine if the kernel is patched or not. If it is, you'll be rooted. If it is not, you'll have to patch it AND install SuperUser/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.

You can root android phone on computer as you like

 

This is true, provided an exploit exists. If there are no exploits, there are now ways to obtain root.
