Android is a great operating system for way too many reasons to name in the introduction of a rooting guide, but one of those reasons worth a quick mention is its uncanny ability to run apps in the background. Being able to run the apps in the background has its distinct grounds for being a feature most enjoy, but it also comes with the downside of using up more battery than it otherwise would have if it didn’t allow applications to run in the background.

Root apps are what you can install after you root your device. These root apps can help you install more features and also uninstall certain things like system apps. There are already great solutions out there for helping with battery issues such as the Greenify app that root users can install. Another great app that people can install after they root Android is the Servicely app to help make the most of the battery life by helping maintain the services running in the background.

These types of apps like Greenify and Servicely are not the easiest to run and won’t do much if you just install the app and keep it sitting there in your app drawer. But if you are willing to set aside a realistic thirty minutes to help understand how the app works and put in the manual work required to help it assist you then these two apps are great and can make your battery lasts much longer.

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 of Note

  • The Android 7.0 software update with build number KOT49H.T530ZSU1AND4 was running on Chainfire’s  Samsung Galaxy Tab 4 10.1 SM-T530 tablet when he created the rooting method available in this guide. However, that does not mean you need to be running the same software update. Chainfire states that it should work on any firmware build number for the Android 7.0 Nougat software update.
  • If you flash the CF-Auto-Root tool using Odin on the Samsung Galaxy Tab 4 10.1 SM-T530 tablet and it causes the device not to boot up, don’t stress. The smartphone is not bricked permanently; it just needs firmware flashed on it manually using the Odin flashing tool. You need to let Chainfire know about the problem by leaving a message on the CF-Auto-Root tool thread so he can update the file, so it starts working again.
  • You need to have the Samsung Galaxy Tab 4 10.1 tablet that comes with the SM-T530 model number to use this guide. Flashing the wrong CF-Auto-Root file for your model number does not work, and you need to flash the firmware with Odin to get the device working again.
  • All versions of the CF-Auto-Root tool need to be flashed with Odin. The Odin flashing tool needs to be used on the Windows operating system.

Files Required

  • Download the CF-Auto-Root tool for the Samsung Galaxy Tab 4 10.1 SM-T530 running on the Android 7.0 Nougat software updates.

  12. When complete, the Odin user interface shows a pass message in a new green box.

The CF-Auto-Root tool has just finished installing the SuperSU application on your Samsung Galaxy Tab 4 10.1 tablets. The SuperSU is the same kind of SuperSU that other people install by flashing it from a custom recovery image. The most common type of custom recovery image to do that today is the TWRP Recovery. The difference is that you don’t have to do any work to find out what version of the SuperSU app you needed to install; the developer of the rooting tool has done that for you. And yes, that can be tricky at times because there is a different version of the SuperSU app for each version of Android. The SuperSU app is what is going to be granting an denying root access to apps that request it. By default, it stops everything from having root access, and you get a message on the devices display asking if you want to grant it root access. When you give root access to a root app, then it can then run on your device. However, if you allow root access to malware or an untrustworthy app, you’ll need to reverse that as soon as possible. Enter the SuperSU app and deny the app root access from the settings whenever you make a mistake or realize there is an app on your device that you do not trust. The SuperSU settings from within the app always allow you to change your mind with regards to the root access for individual apps.
