Not as many people know what Linux is in comparison to Microsoft’s Windows, so it only makes sense that people aren’t as familiar with the term ‘root user.’ The root user is to Linux what the administrator is to Windows which is the person who is using the account with all the permissions.

These permissions are usually with regards to what people can install and uninstall. Manufacturers like Samsung often like to hide their stock apps behind the wall of the system partition—a place that non-rooted users cannot access and therefore cannot remove the apps. Smartphone carrier networks also love to do the same thing.

The apps that are hidden behind the system partition are called the system apps, and we can remove them by becoming the root user and then installing the Titanium Backup app. Titanium Backup is one of most people’s favorite root apps to install because it is way better at backing up the data on your phone and tablets than something like the Helium app. Additionally, Titanium Backup also can uninstall things, including every system app. The way Titanium Backup works is by being able to read every apps data, and that is why you can backup everything so easily. The developers have also noticed they had an extra ability here to allow people to remove apps from the system partition too, so they allowed it. Now all you need to do is make sure you remove all apps that can be removed without bricking the device, and you can enjoy the Android operating system with better battery life and even hardware performance.

What Is Rooting the Android Operating System?

When you buy a new smartphone, you might not know it, but the Android operating system is in a “locked” state. For the most part, it will not make much difference to you: most apps are still available to use, and there are benefits to this locked state such as better security. When you root the Android operating system, you are gaining full administrative rights over the OS.

Why Would You Want to Root Android?

Gaining full administrative rights over the operating system has some perks to some people. For example, out of the millions of applications available on Google Play, some of them will not be able to run on your device unless it has root access. Until you have a specific need for wanting Android rooted, you probably want to leave Android as it comes out of the box. But if you need to unlock an app, then that is when you want to look into rooting methods. Using more apps is only one example of why you may want root access, here is the full list of benefits:

  • Unlock more applications. Some of the apps available for Android cannot run unless you have root access. This is because the app’s features cannot run without the root permissions because the features require the full system access before they can be useful.
  • Better battery life. Smartphones are great, but they have one caveat, which is each time you recharge the battery, it loses some of its overall lifespan. That means smartphones, in general, do not make great investments, and if your weekly paycheck is low, you will want to limit the number of smartphones you go through. One of the ways you can do that is by removing bloatware and creating a better battery life.
  • Bolster performance. If you are the budget-conscious shopper, you may want to increase the device’s performance. This can be done by removing the bloatware as well. The more processes you have running, the more memory that is used. By removing some of the apps, it can help lighten the load on your hardware.
  • Customize Android with themes. With root access, you can download and install any theme that’s at your disposal. That includes any customized theme you can find.

What Are the Risks of Rooting?

If you are buying a smartphone that is not running iOS, then it is probably the Android operating system that you want running as the ideal software to pair with your shiny new hardware. It is, in fact, the Android OS that offers you the chance to customize the OS considerably more than iOS: custom themes, run any app you know about, the works. For many users, the “openness” of an operating system is important, because it offers them more freedom which means running into fewer problems with their investments. But there is a reason iOS likes a far more locked approach: the ability to customize is not for everyone, and if you do not know what you are doing it can lead to a lot of problems which can define your time with the OS rather than freedom.

With power (full admin permissions) comes greater responsibility. Here are some of the main risk factors when it comes to rooting:

  • Malware becomes a larger threat. You might read the occasional news article about how new malware is wreaking havoc in parts of the world on Android. But the Android operating system with root access becomes considerably more vulnerable to exploits because applications are no longer prisoned off in their own sandbox environments. This means if you accidentally download malware, it can do more damage because it can spread throughout the operating system and even jump into other applications and potentially view sensitive data.
  • You can accidentally brick the smartphone. There is always a chance that you end up bricking the smartphone before you had the opportunity to use it with root access. That is because if you are going to brick it, it is going to happen during the rooting process.
  • You may void the warranty. Most manufacturers do not allow you to root the Android operating system and still get to bring it in for repairs under warranty. Whether they are legally meant to do that or not is another question, but it is now common knowledge that most do not want to help you if they find out you have unlocked the OS with root access.

Details We Should Know

  • Chainfire created the CF-Auto-Root file in this guide based on the LRX22G.P900UBU0BOI1 firmware build number. You do not have to be running that same firmware. You can run on any firmware that is on Android 5.0.2 Lollipop. All you need is the Samsung Galaxy Note Pro 12.2 that comes with the SM-P900 model number.
  • If you are finding the Samsung Galaxy Note Pro 12.2 SM-P900 does not boot after flashing the CF-Auto-Root tool, leave a message letting Chainfire know about the issue along with the new recovery image from the new firmware on the CF-Auto-Root thread at the XDA-Developers website. Sometimes new Android versions bring new bootloaders which temporarily stops CF-AUto-Root from working until he updates the files.

Files We Need

  • Download the CF-Auto-Root tool for the Samsung Galaxy Note Pro 12.2 SM-P900 running on Android 5.0.2 Lollipop software updates.
  • Download the Samsung USB Drivers for the Windows computer.

In conclusion, that is how to root Samsung Galaxy Note Pro 12.2 tablet with the SM-P900 model number when it is running on the Android 5.0.2 Lollipop software updates. The guide makes use of Chainfire’s SuperSU by getting it installed with an automatic one-click rooting tool that Chainfire names CF-Auto-Root. The result is SuperSU is now sitting in the app drawer as soon as it reboots and it is ready to grant the rooting permissions to any app that requests it with your approval.

That means you can officially open the Google Play Store app or your web browser and start installing the root apps. Anyone who needs some suggestions on what root apps to install can check out our list of the best root apps for the Android operating system.
