You will find it hard to find anything to do with the Android operating system that is more appealing than becoming the root user. While power trippers in the real world are frowned upon and it is known to be a weakness to have the need to have constant power, few people do not believe having the maximum amount of power over the software that runs on their smartphones is not a good thing. That is what rooting the Android operating system does. As soon as you are the root user it is down to you what is installed and uninstalled, and there is nothing you cannot make the decision for to do with installing apps.

Most people are not aware just what apps can do. No longer are apps just for playing games and having fun. Now you can find apps out there available from the Google Play Store and other websites online that allow you to make changes to the Android user interface, it features, how long the battery lasts, what stock apps will remain and a bunch of other useful features including the ability to take full backups without having to go anywhere near a computer and Android Debug Bridge. The last point in itself is a good one because there is no other way to take a full backup on Android without setting up Android Debug Bridge on a computer and most people will be all too aware of that fact since backing up is such a regular thing to do.

Here is everything you need to become the root user on the Samsung Galaxy Tab 3 SM-T312, so the choices are yours to be made with regards to what is installed and uninstalled on your device, so you no longer have to do things like support the system apps taking up too much memory:

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 was running the JDQ39.T312JVUAMK4 firmware build number on the Samsung Galaxy Tab 3 SM-T312 when he managed to come up with the root tool that is available in this guide. That rooting tool I am referring to is, of course, another version of the CF-Auto-Root tool. You do not have to be running on the same firmware build number that he was running when you follow this guide to get root access on the tablet. All you need to do is make sure you are running versions of the Android 4.4.2 KitKat software updates and that you have the Samsung Galaxy Tab 3 tablet that comes with the SM-T312 model number.
  • You can let Chainfire know if the rooting file is not working by leaving the new recovery image found in the firmware you are running on the CF-Auto-Root tool thread made at the XDA-Developers website for him to see. The one problem that prevents the CF-Auto-Root tool from working is a new bootloader. A new bootloader can sometimes come in new versions of Android and when they do it can cause a device not to boot after flashing the rooting file. That is when you know that the file needs updating. That problem should not happen in our guides because we based them on one Android version only and thus eliminating the chance of updates bringing new bootloaders.

Files We Need

  • Download the CF-Auto-Root tool for the Samsung Galaxy Tab 3 SM-T312 tablet running on the Android 4.4.2 KitKat software updates.
  • Download the Samsung USB Drivers for the Windows computer.

  4. Extract the rooting file to the Downloads folder where the rooting file ended up by default after you downloaded it at the beginning of the guide.
  5. Run the Samsung USB Drivers on the computer so that when you do connect the Samsung Galaxy Tab 3 tablet to the computer with the USB cable the flashing tool can detect the device.
  6. Open the Downloads folder and click on the Odin flashing tool executable file so that your flashing tool user interface opens on the computer.
  7. Boot the Samsung Galaxy Tab 3 SM-T312 tablet into the download mode and then connect it to the computer with the USB cable that is used for charging the battery.
  8. Check that Odin shows a blue or yellow color coming from the ID: COM port (usually blue with Odin 3.10) and that the message shows the added message. (These two things mean you have the Samsung USB Drivers working correctly).
  9. Click on the AP button from the Odin user interface and the click through to the Downloads folder where you extracted the rooting file earlier and select the rooting MD5 file to upload to the Odin.
  10. Do not make any changes to the default settings that are available from the Odin flashing tool user interface.
  11. Click on the Start button and the rooting of the Samsung Galaxy Tab 3 SM-T312 begins.
  12. Check what is shown on the display by the CF-Auto-Root tool which is programmed to run you through everything that is happening on the Samsung device.
  13. Wait until the Samsung Galaxy Tab 3 shows a message on the display that says it is going to reboot in ten seconds.
  14. Look back up at the computer and Odin and wait until it shows a pass message inside a new green box from the Odin user interface.

In conclusion, that is how to root the Samsung Galaxy Tab 3 SM-T312 tablet running on the Android 4.4.2 Kitkat software updates by flashing another version of Chainfire’s CF-Auto-Root tool that has been specially made to work on this device. The CF-Auto-Root tool has just installed a modified cache and a modified recovery which then installed the SuperSU app (also made by Chainfire). Since it was installed from the modified cache and recovery, it is now enabled on the Samsung Galaxy Tab 3 tablet and granting you the rooting permissions that it needs to run.

Since rooting the Android operating system running on the Samsung Galaxy Tab 3 tablet is all about what you can install and uninstall, you need to know the names of the apps that you want to install. Even if it is uninstalling that you are hoping to do, you still need to install apps that then help you uninstall things like the system apps. The Titanium Backup app is one of the apps that can not only help people backup the data on a device but also remove the system apps that are eating away at the memory and causing the device to be bloated. Anyone who needs some help learning the root app names can check out our guide on what we believe are some of the best root applications you can install on the Android operating system. Remember the names that you want to install land then search them from Google or the Google Play Store to find out where they are available for download.
