Becoming the root user on the Samsung Galaxy S5 smartphone is going to allow you to install any of the apps that you want. It is another way of saying master control of the operating system. There are a few ways people root the Android operating system which gives them the access to the root file system that they desire. Often is depends on what you are looking to do with that root access that determines the direction that people go in and other times it just depends on what it available out there for people to use.

The Samsung Galaxy S5 smartphone series is a popular one and as such, there are a few options for people. Those who are wanting to install custom ROMs to go along with the root access prefer installing a custom recovery like TWRP and then flashing a version of the SuperSU from that recovery. Other people do not like a custom recovery and would prefer having the stock recovery running at all times. For all those people there is the CF-Auto-Root tool by Chainfire.


  • You must install a custom recovery on the T-Mobile Samsung Galaxy S5 SM-G900T phone before you can have it rooted using the guide below. The custom recovery partition is what we need to enable the SuperSU application successfully so that it works.
  • Note that rooting the Samsung Galaxy S5 smartphone voids the warranty and void it forever because it comes with Samsung’s Knox security. The Knox security means that when you trip Knox the warranty does not work even when you unroot the smartphone later down the track.

How to Root Samsung Galaxy S5 SM-G900T T-Mobile on Android 6.0 Lollipop Using CF-Auto-Root

  1. Connect the T-Mobile Samsung Galaxy S5 smartphone to the computer with the USB cable.
  2. Copy the SuperSU 2.71 .zip file over to the internal storage SD card folder and then unplug from the computer when it is done.
  3. Turn off the Samsung Galaxy S6 smartphone.
  4. Boot the Samsung Galaxy S5 phone into the recovery mode using the same hardware combination as the stock recovery and it boots into the custom recovery that you installed earlier.
  5. Choose to take the NANDroid Backup if you have not backed up yet just in case you want to restore the data later and apply a hard reset to get out of trouble.
  6. Tap on the Install button from the main recovery menu and then follow the guidelines for uploading the SuperSU file that is on the SD card and then installing it.
  7. Choose the option to reboot the system once the SuperSU installation is complete and the smartphone reboots back into the normal mode where you can see the SuperSU app is available from the app drawer.

In conclusion, that is everything you need to root the Samsung Galaxy S5 SM-G900T smartphone when it is running on the Android 6.0 Marshmallow software updates. The SuperSU for Marshmallow is what Chainfire calls the systemless root version because it no longer requires any modification of the system partition. The SuperSU application that you can see in the app drawer does not need any adjusting now. All you need to do is open up the Google Play Store application and start installing the root apps like the Titanium Backup app. The SuperSU app can be opened, and you can check out the options available inside if you want to check it out, however.

There are many reasons why people choose to root the Samsung Galaxy S5 smartphone after they have installed a custom recovery. Those who are doing it because they think they need to get root access before installing a custom ROM can save themselves the time because it is not a requirement. You can install a custom ROM after you have a custom recovery installed, and some of the ROMs even come pre-rooted. Just about everything to do with rooting the Android operating system comes from applications both on the Google Play Store and other sources online. Root access is about getting access to the root user account so you can install and uninstall whatever you want on the Android operating system that is already running on the smartphone. That means you have better backing up apps that can backup everything that is on the device because an application like the Titanium Backup app can read everything on the device.

CF-Auto-Root on XDA-Developers. Chainfire, the developer of the CF-Auto-Root tool available in this guide, has created a CF-Auto-Root tool thread on the XDA-Develoeprs website. You can use the CF-Auto-Root thread on the XDA-Developers site for requesting new root methods for devices that are not currently available.

Encryption. Note that flashing a CF-Auto-Root file (regardless of the device) wipes the data if the device storage is encrypted. For everyone else, there should be no data loss when rooting with the CF-Auto-Root tool.

Samsung’s Knox security. Some smartphones and tablets in the Samsung range come with Samsung’s Knox security. The CF-Auto-Root tool trips Knox which prevents you from unrooting and using the warranty again.

Flash Counters. Any device with a target flash counter is triggered when using the CF-Auto-Root tool. Chainfire’s Triangle Away supports many devices for this problem.
