Use Odin to root Android 4.4.2 for Samsung Galaxy Tab 4 8.0 T331

The 3G model of Galaxy Tab 4 8.0 tablet can now be rooted using the Odin tool and Chainfire’s Auto Root file. Use this guide if you want to learn how to successfully achieve root and not lose any files in the process.

Rooting your device is easy as you simply have to flash a single file using a small tool like Odin. If you root your tablet you will offer it support for new custom Recoveries, custom ROMs or kernels as well as support for installing new better apps that are only working with root-based devices.

If you want to successfully achieve root for your device then we strongly recommend you to take a look at the preparation info below:

  • use this guide only with the 3G variant of Samsung Galaxy Tab 4 8.0 device.
    – your tablet should have the model number set to SM – T331.
    – do not try to root any other tablet nor smartphone in case its model number doesn’t match the one listed in this article.
  • install the Samsung USB Drivers on your computer.
    – without these drivers present Odin cannot detect the tablet and you can’t complete root.
  • disable any antivirus application or security program that you might have running on your PC.
    – also, make sure to disable the Samsung KIES if it is installed on your PC.
    – all these apps will block ODIN from installing any new root files on your Galaxy Tab 4 8.0.
  • enable the USB Debugging option from the Developer Options section.
    – if the Developer Options menu is not listed, then you will have to un-hide it using the info here -> that’s a guide for Galaxy S5, but it will work with any Samsung device.
  • make sure that your tablet’s battery charge level is over 50%, so that the device won’t switch off in the middle of the rooting process.
  • this post is for advanced users who want to tinker with their device, so you shouldn’t blame us in case you brick the Galaxy Tab 4 8.0 nor in case you lose any important files in the process.
  • read the entire guide and do not skip any steps.

Since you’ve read all of the above now you can continue with the rest of this tutorial and start learning how to achieve root for your device.

Note that this guide will work with any Android 4.4.2 KitKat build you might have installed on your device.
