Flash Official L720VPUFNAE Android 4.4.2 OTA Update for Sprint Galaxy S4

Sprint and Samsung have launched the official Android 4.4.2 KitKat firmware update files for the Galaxy S4 device. Use this tutorial and learn how to manually update your device without bricking its firmware.

If you’re still waiting on the official OTA Update to Android 4.4.2 notification to arrive on your Sprint Galaxy S4 device, then you might want to learn that you can manually update your device using the firmware tar.md5 and ODIN to install it. Before starting the update you will need to read the preparation guide below:

  • use the guide only with the Sprint variant of Samsung Galaxy S4.
    – don’t try to update any other Samsung Galaxy S4 models with the files that I’ve listed in the tutorial.
  • download and install the Samsung USB Drivers on your computer before starting the updating process.
    – this installation will make sure that your phone will be recognized by ODIN, the app you’ll use to flash the new official ROM.
  • disable all antivirus apps and the Samsung KIES software, so that no Windows app will block the Android 4.4.2 official update.
  • go to Developer Options and enable USB Debugging.
    – in case Developer Options menu doesn’t appear in Settings, then you should open the About Device section > go to Build Number and press seven times on the build number text — it will enable Developer Options.
    – go back in Settings, find Developer Options, open it and then enable USB Debugging.
  • note that in case your Sprint Galaxy S4 currently runs a custom ROM, then the phone will be wiped.
    – the same goes for any custom Recovery that you might have installed on your phone, as the stock Recovery from Samsung will be flashed over the custom one.
    – remove its external sdcard if there is any connected and then continue with the tutorial.
    – if the device is 100%, stock then you will not lose any files in the process.
  • if you want you can backup data from installed apps, SMS text messages and other data with Helium tool for Android.
  • you can sync Contacts info with your Gmail, too – this will save all your phone numbers and People details with your default Gmail account.
  • make sure that your phone’s battery charge level is over 50%, so that the Sprint Galaxy S4 will not switch off in the middle of the updating process.
  • this is a post that should be followed by advanced users, you can’t blame us in case you lose any data in the process.
  • if you’re unsure about updating your phone, then you can go to its Settings menu, More and then About Device. Open the Software Updates section and click the ‘Check for Updates’ button.
    – if there is a new update build available you should click Download and Install it, as you won’t need this guide any more.
    – if there is no update available, then you can use our guide.
  • read the entire post and make sure not to skip any steps.

These were all the guidelines that you had to go over before continuing to the next part of this post. If you have other questions use the comments field below.

Install official Android 4.4.2 KitKat ROM for Sprint Galaxy S4:

  1. Download the L720VPUFNAE Android 4.4.2 firmware from here.
    – that’s a download link from our friends at SamMobile, which is why you need to create an account first for you to be able to download the updating zip file.
    – create an account and then click the Download button.
  2. Extract the L720VPUFNAE_L720SPTFNAE_SPR.zip content and save it to your computer desktop.
    – you will get the “L720VPUFNAE .tar.md5” file.
    – don’t extract any further than that.
  3. Download Odin3 v3.09 zip from here.
    – extract the zip contents and save them all in a single desktop folder.
  4. Power off your Sprint Galaxy S4 now completely.
  5. Boot the device in Android Download Mode.
    – if you can’t boot Sprint Galaxy S4 Download mode, then read here.
  6. Launch Odin executable on your PC.
  7. Connect your Sprint Galaxy S4 to your computer using the USB Data Cable.
    – wait for ODIN to detect the phone and then continue with the tutorial.
    – if the phone isn’t detected by Odin 3.09, then you will need to re-install Samsung USB Drivers (here), and repeat the entire tutorial from start.
  8. When everything is set you should click the AP button in ODIN screen. Browse your computer for the L720VPUFNAE .tar.md5 file and load it in ODIN.
    – make sure that the Re-Partition option is not enabled and don’t change any other default settings.
    – when ready get to the next step.
  9. Press START when you’re ready for Odin3 v3.09 to start the update process of your Sprint Galaxy S4 to Android 4.4.2 KitKat official ROM.
    > don’t press any buttons until the process is complete.
  10. When the installation is complete you will see the confirmation message from ODIN app and the Sprint Galaxy S4 device rebooting.
    – you can disconnect the device from your computer when its boot animation logo appears.


These were all the steps that you had to take in order to complete the updating process of your smartphone to Android 4.4.2 KitKat.

NOTE: if ODIN freezes for ten minutes or more, then you should close the app, then remove the phone’s battery, re-insert it after several seconds have passed by and then repeat the entire tutorial starting with step 1. Ask for more help in comments in case you can’t do it.

NOTE 2: if ODIN says that the installation has been successful, but the phone is unable to boot in normal mode you will be forced to apply a Factory Reset for your device. This will wipe the system partition and force the Sprint Galaxy S4 to boot the new Android 4.4.2 KitKat firmware update.

Here’s how to apply Factory Reset for your device:

  • power off the phone completely by removing its battery.
  • re-insert the battery after five seconds have passed by.
    – make sure that the device is not connected to your PC.
  • boot the phone in Recovery Mode.
  • select ‘wipe data/ factory reset’ and then confirm process.
  • reboot the Galaxy S4 Sprint in normal mode after Factory Reset is complete.
  • wait for the Android 4.4.2 homescreen to appear and use your Google Account to take control over its new firmware.

I hope that you did manage to complete installation.
