An Important Reminders:  Pros and Cons on a Rooted T-Mobile Galaxy S6 SM-G920T


Pros:


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 requires 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, once the phone is rooted you can then modify its system from which you can  install a custom recovery of your choice, a custom firmware base on Android Open Source Project (AOSP) or just a rooted stock firmware from your trusted after-market developers.

Cons:


These are the known facts why you should refrain from rooting.  It  is already known to others but I just want to and must acknowledged these important reminders to those who have no any idea why I do not want  them to engage into rooting in the first place.

Rooting will 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 fix then you might cover all the cost of the paperweight if they found out that it was rooted.

Rooting will 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:
CURRENT BINARY: Official
SYSTEM STATUS: Official
KNOX WARRANTY VOID: 0 (0x0000)

But a rooted and modified Galaxy S6 SM-G920T will say such as this:
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
KNOX WARRANTY VOID: 1 (0x0500)

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)”. 

Rooting will break some of the pre-installed  Apps

Some folks who've had  a rooted  Galaxy S6 G920T  have found some unusual issues regarding of some important  apps.  Without any detailed reports of what exactly causes the problem the root breaks some particular applications and the device will not work properly.

Check out this list as I will just add or remove if and when we found new issues and or if it is already got fix.
  1. Google Play Movies streaming is not working.
  2. Prevents the device from going into deep sleep. (Read the how to fix it below)

A rooted phone will no longer get a Software Update support

Samsung frequently rolls out software updates which often arrives once a month or two.  A new updates  particularly brings 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, what is official or custom, was it 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 doesn’t knew about it, they can get a message that says something like “The device has been modified. No software update is available.”  or similar message to that.

So now you have learned the ups and downs on a rooted Galaxy S6. So it is now up to you to decide if you want to root or maybe not.  If you want to achieve root just  continue reading on the guide below but if you are aware the downside of  having a rooted phone then you still have the chance to refrain from rooting and keep your device untouched.
