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:

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.

  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.

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.
