[How To] Update Galaxy S3 LTE to Android 4.4 KitKat

Users of Galaxy S3 LTE can now enjoy the taste of KitKat Google presented with Android 4.4. It’s the unofficial CyanogenMod 11 ROM that brings the KitKat update on Galaxy S3 LTE.

As regards official KitKat update for the Galaxy S3 LTE from Samsung, well, chances are more than not that it will never happen, as S3 is already past the update chart.

CM11 presents a brilliant option for Galaxy S3 LTE users to try the KitKat update, and even though it’s in not complete, and remains in development, it’s still good for try — to taste the KitKat.

Let’s see how to install the custom Android 4.4 KitKat update using CM11 on your Galaxy S3 LTE.


Warranty may be void of your device if you follow the procedures given on this page.

You only are responsible for your device. We won’t be liable if any damage occurs to your device and/or its components.


To make sure your device is eligible with this, you must first confirm its model no. in ‘About device’ option under Settings. Another way to confirm model no. is by looking for it on the packaging box of your device. It must be GT-I9305!

Do not use the procedures discussed here on any other Galaxy S3 (including the S3 devices, T-Mobile, Sprint and international ones) or any other device of Samsung or any other company. You have been warned!


You must do this pre-installation stuff before attempting to install the ROM on your Samsung Galaxy S3 GT-I9305 in order to avoid any complications later, and have a smooth and successful process.


Back up important data and stuff before you start playing around here as there are chances you might lose your apps and app-data (app settings, game progress, etc.), and in rare case, files on the internal memory, too.

For help on Backup and Restore, check out our exclusive page on that linked right below.



If your android device powers off due to lack of battery while the process is underway, it could damage the device.

So, make sure your device is adequately charged — at least 50% battery of the device.


If you haven’t used a custom recovery, either CWM or TWRP, before, to install a .zip file of a ROM on anything else, then we suggest you first watch a video of that, given right below, to get familiar with the process.

Just fyi, the video below shows installing a .zip file (of recovery) on Galaxy S3, but it doesn’t matter as the process remains exactly same. So, once you are finished with video, jump to downloads and step-by-step guide below.

    • Press and hold  Volume Up + Home + Power buttons together and release them as soon as you see the Galaxy S3 logo.

  3. Perform a Factory Reset (This will delete all apps and their settings and game progress). For this:
    • Select Wipe data/Factory reset, then select Yes on the next screen to confirm factory reset (screenshot)
  4. Install the ROM file first (CM11-1.1-11-12-13-UNOFFICIAL-jfltevzw.zip). For this:
    • Select Install zip » Choose zip from sdcard (or external sdcard, you know where your files are) » browse to the location where you saved the file and select the CM11-1.1-11-12-13-UNOFFICIAL-jfltevzw.zip » select Yes on next screen to confirm installation of the file.
      How to Flash File in CWM Recovery
  5. Now similarly flash the pa_gapps-full-4.4-20131114-signed.zip, as you did in step 4.
    └ Make sure to first flash the ROM file and then the Gapps file.
  6. Now, do a factory reset as you did in step 3.
  7. Reboot your device. For this, go back to the main menu of recovery and select reboot system now.

  1. Didn’t work with cwm. It kept saying the .zip file was incomplete. I installed twrp instead and it installed without a hitch.
