Root Samsung Galaxy S6 SM-G920F international model variants with some simple steps using CF-Auto Root. The Samsung Galaxy S6 SM-G920F is running in Android 5.0.2 Lollipop firmware, but this root method has been tested and a proven for long years on most Samsung Android smartphones and tablet before the Galaxy S6 exist. To root your Galaxy S6 SM-G920F, you may only use the “CF-Auto Root”. This root method has been continuously developed by ‘Chainfire’ and it was already tested beforehand by many Galaxy S6 users even it was just freshly launched.

Once you have gained root on your Samsung Galaxy S6, you can then achieve the Superuser access which simply means that it grants you with a full privilege to control your device. One of these access is to install any 3rd-party apps that require root access before you can actually install it into your Galaxy S6. Without root access, you cannot technically run those apps within your phone.

Moreover, to root is to modify the phone. You can also install custom recoveries and custom firmware from trusted aftermarket developers once you have gained root on your Galaxy S6 SM-G920F.

Important Reminders:

It is basically fun to have a rooted Galaxy S6 because you have the full access to modify it, but there are some several downside of a rooted phone. So those who have just heard about rooting, then here are some few facts why you should learn first before you take the plunge.

1.) Voids the warranty of your Galaxy S6.

Yes, it technically voids the warranty of your Galaxy S6. Some dealers might not render a rooted phone. So if somehow there is something wrong with it and you have to send it back to your dealer for the fix then you might cover all the cost of the paperweight if they found out that it was rooted.

2.) Tripped KNOX

KNOX basically an apps which also includes a security counter that is hidden in the system data. A tripped KNOX will no longer work and this is not irreversible. This is a new security policy from the manufacturer and the dealer and was pre-installed on all Galaxy S6 and S6 Edge devices, either its unlocked to a carrier branded models.

You can see this stuff when you reboot your Galaxy S6 into download mode. You can access it when the phone is turned off, then by pressing Volume Down, Home, Power button at the same time. And then the Volume up.

A normal Galaxy S6, I mean untouched, unrooted and unmodified simply shows like this:

But a rooted and modified Galaxy S6 SM-G920F will say such as this:

It will technically show you the system has been modified and already set into "custom" from the default "official". Then KNOX Warranty void counter has been tripped by showing the number "1 (0x0500)".

3) You will no longer receive a Software Update

Samsung frequently rolls out software updates which often arrives once a month or two. New updates particularly bring several improvements, bug-fixes, and other system enhancements. Now, a rooted Galaxy S6 cannot get new software update anymore. During the software update processes, there's a consistency check happens. It will basically check the phone from what software version it has, was it is official or customize and was it is rooted or not.

So once it finds out the phone was rooted or running on an unofficial firmware; the update will tell the user that there is something with the phone's system OS. So oftentimes some users who don't know about it, they can get a message that says something like “The operating system on your device has been modified in an unauthorized way. Try downloading software updates using Smart Switch on your computer or visit a customer service center.” or similar message to that.
