Becoming the root user is appealing because it lets people choose what they want to have installed on the device in question. It allows them to be the ones to decide what system apps are removed, so there is only the minimum amount resources being used which then becomes beneficial to the user like yourselves. The root user can also choose to install any number of the root applications that are in existence today. There are thousands of these root apps that will not run unless you have granted the required root permissions over the operating system first and that is precisely what we are doing when we follow a guide like the one below that teaches you how to root Samsung Galaxy Tab Pro 12.2 SM-T900 tablets with the CF-Auto-Root one-click rooting tool.
The following guide is made to root Samsung Galaxy Tab Pro 12.2 SM-T900 when they are running on the Android 5.1.1 Lollipop software updates by flashing Chainfire’s one-click rooting tool known around the world as CF-Auto-Root.
- You need to have the Samsung Galaxy Tab Pro 12.2 tablet that has the SM-T900 model number to use the version of the CF-Auto-Root that is made available in this guide. Any other model number will get bricked, and you will need to flash the stock ROM from Sam Mobile to get it working again.
- You need to have the Windows operating system booting up on the computer that you plan on using in this guide that is running the flashing tool app. The Odin flashing tool only works on Windows.
BEFORE WE BEGIN
- There are two versions of the Samsung Galaxy Tab Pro 12.2 SM-T900 tablet. The CF-Auto-Root tool available in this guide is developed for the exynos5 version of the SM-T900 model number only. Make sure you have the right model, or it will brick the device, and you will need to flash the stock ROM from the Sam Mobile website to get it working again.
- Chainfire had the LMY47X.T900XXUBPA1 firmware build number running on the Samsung Galaxy Tab Pro 12.2 SM-T900 tablet when he created the version of the CF-Auto-Root tool that is available in this guide. You don’t have to be running on the same firmware version as him. You just need to make sure that you have the right SM-T900 model number and that it is running on Android 5.1.1 Lollipop and the guide should work for you.
- Unlock the Developer Options menu on the Samsung Galaxy Tab Pro 12.2 SM-T900 tablet so you can then enter it and turn on the USB Debugging Mode. That USB Debugging Mode is what then allows you to have changes made to the Android operating system. Without it, the rooting file cannot get flashed correctly, and the rooting fails.
- Install the Samsung USB Drivers on the computer before you get started with the guide below. That way when you do connect the Samsung tablet to the computer with the USB cable it can be picked up and connected correctly to the Odin flashing tool which then allows for the rooting to happen.

You can see the SuperSU available from the app drawer as soon as your tablet reboots, and you need to leave it on the device if you are to remain rooted.
