Samsung has released the official Android 5.1.1 Lollipop OTA Update for all Galaxy tab 4 8.0 LTE users, but not all of them are getting the new firmware at the same time.

The tutorial below can be used as an alternative upgrading method, as you will have to use Odin3 v3.10.6 app for Samsung devices in order to flash a brand new official update. Android 5.1.1 Lollipop brings bug fixes and stability improvements for your Galaxy Tab 4 8.0 LTE tablets.

Before you can start the installation process you should read the following guidelines:

  • use this guide only with the Samsung Galaxy Tab 4 8.0 LTE tablets.
    - your tablet's model number should be SM - T335.
    - do not try to update any other devices with the files that you will find in this post.
    - the model number of your tablet can be checked under Settings> About Device menu.
  • download and install the Samsung USB Drivers on your computer.
    - after you've installed the usb drivers you will surely be able to successfully connect your tablet to your PC.
    - for the updating process you will use Odin3 v3.10.6 application, which is why you need to have the official Samsung usb drivers installed on your PC.
  • disconnect Samsung KIES and any antivirus apps from running while Odin3 v3.10.6 app is opened.
    - these applications are going to try and block Odin from flashing any firmware files on your tablet.
  • your tablet should have the USB Debugging option enable in Developer Options menu.
    - if you can't find Developer Options, then you should go to Settings> About Device and tap 7 times on the Build Number section.
    - now Developer Options is going to appear under Settings menu, open it and find USB Debugging in order to enable it.
    - the USB debugging will help your tablet detect the PC and allow it to flash the update files.
  • if your tablet is rooted, then the updating process will revoke its root access.
    - any custom Recovery that you might have installed on your device will be replaced by a stock Recovery.
    - if you haven't rooted nor installed a custom Recovery on your device, then this piece of information doesn't concern your device.
  • in case you are installing the new firmware update file over a custom ROM, then an extra 'factory reset' step will have to be applied after the Android 5.1.1 update is complete.
    - the 'factory reset' steps are listed at the end of this article.
    - 'factory reset' means that you will lose the system memory partition, while no files are removed from the internal storage.
    - the system partition is where the previous ROM has stored all of its files.
  • if your tablet is 100% stock Android, then you won't lose any files during update and you can continue straight to the installation process below.
  • note that this guide is for advanced users, we cannot be held responsible in case you lose any data in the process, nor in case you end up bricking your device.
  • check the battery charge level of your device, make sure that it is over 40%, it will prevent your device from powering down during installation.
  • read the whole guide and do not skip any steps.

Since you've read all of the above you can now continue to the next part of this post.

If everything went according to plan and you've updated your tablet, then you can close this post. The extra help below should also be checked by those that have installed the new update over a custom ROM.


In case Odin says that the update has failed, or it has gotten stuck at some random screen, then you should try to repeat the whole guide more than once. Make sure that you won't skip any steps and that your tablet meets all the requirements in case you retry installation.


If Odin has shown the 'PASS' alert, but your tablet is stuck at the boot animation screen or it has entered in a boot loop, then you will be forced to try the 'factory reset' instructions below.

The 'factory reset' steps need to be applied by those that have installed the update over a custom ROM, too. Here's how to do it:

  • power off the tablet.
  • boot it in Recovery Mode.
    - Volume Down, Home and Power buttons pressed at the same time until the Recovery Mode menu appears.
  • select 'wipe data/ factory reset' option.
  • confirm.
  • reboot the tablet in normal mode and that would be all.
