The Samsung Galaxy S4 LTE model number I9505 has received the Android 4.3 official OTA Update recently. Now, we've got a guide that allows you to apply root for it. Use this tutorial to apply root and learn how to complete all actions without bricking your device.

Note that the new OTA Update by Samsung adds the latest KNOX Flags security and this guide will void the warranty. KNOX Flags are tripped by this root which will change KNOX 0x0 value to 0x1. Rooting is easy and you should be able to complete the entire tutorial without bricking the Galaxy S4 LTE.

First you need to take a look at the preparation guide below and learn how to correctly configure your device for the rooting process. Check the guidelines:

  • Use this post only for the Samsung Galaxy S4 model number I9505. This is the LTE International model.
  • Don't attempt to flash this root on a different Galaxy S4 variant, as you will brick it. Also, don't flash the files you find here on any other Android smartphone / tablet.
  • CF Auto Root is the tool we're going to use to apply root for your device. The version you find here has to be used on XXUEMJ5 Android 4.3 firmware.
  • KNOX Flags are tripped by this root and you will lose warranty.
  • Make sure that you have the Samsung USB Drivers installed on your PC. If you don't then you can download them from here.
  • Disable Samsung KIES software from running on your PC.
  • Disable all antivirus applications too. These apps will interfere with the rooting process and Odin, the tool we'll use to flash CF Auto Root for XXUEMJ5 firmware.
  • Enable USB Debugging from Developer Options menu.
  • After you root the device there is a risk for the Android 4.3 XXUEMJ5 rooted to get stuck and being unable to boot in normal mode. That's when you will be forced to apply a factory reset and the device will boot the new rooted firmware.
    - usually such things don't happen, but in case it happens with your device, then you should take a look at the end of this post, as you will learn how to wipe data and force the phone to boot in normal mode.
    - factory reset deletes the system partition and you can backup data from installed apps using the Helium app from Play Store - link here.
  • Sync Contacts info with your Gmail account. It will preserve all your saved phone numbers to your Google Account cloud storage. All phone numbers will be restored to your phone after you enter the same Google account info.
  • Use this tutorial only if you're an advanced user who wants to tinker with his phone. Don't attempt to flash any files in case you don't know what you're doing or you don't want to void the phone's warranty.
  • Do not blame us in case you brick the phone or lose important data in the process.
  • Make sure that the phone's battery has enough power left in it. If the charge levels are under 50%, then we strongly recommend you to charge your device, so that it won't switch off while you're in the middle of the rooting process.
  • If you have any other questions, then you should use the field at the end of this post.

Now that you know all of the above, continue to the next part of this post and learn how to root your device.

How to root Android 4.3 XXUEMJ5 stock Jelly Beam ROM for Samsung Galaxy S4 I9505 LTE:

  1. Download the CF Auto Root for your phone from here.
  2. After the download is complete, unpack the zip and save the files on your computer's desktop screen.
    - you will get a file with the tar.md5 extension, so you shouldn't extract any further than that.
  3. Download Odin3 v3.07 from here.
    - extract its contents, then place them all in a desktop ODIN folder.
  4. Power off your device now.
  5. Boot the phone in Download Mode.
    - it can be done if you press at the same time Volume Down, Home and Power buttons.
    - release the buttons only when the Warning! screen appears, then press Volume Up to confirm that you wish to boot in Android Download Mode.
  6. Launch Odin executable on your computer.
  7. Now, connect the Galaxy S4 LTE to your PC using the USB cable.
    - if ODIN doesn't detect the phone, then you should try to plug the device in a different USB port or re-install the Samsung USB Drivers.
    - if Odin recognizes the device, then you can continue to the next step.
  8. First, click the PDA button and load the '.tar.md5' file, the one extracted in step 2.
    - make sure that Re-Partition option is disabled.
    - don't edit any other Odin default settings and continue to the next step when you're ready for the rooting process.
  9. Press START for ODIN to start the root process of your Galaxy S4 I9505 LTE.
    - the root takes several minutes to complete, don't press any buttons until this is complete.
  10. After the root is complete you will see the PASS messages shown by ODIN, while your Galaxy S4 will reboot in normal mode.

These were the steps you had to take in order to apply root for your device.

If you can't complete the root, then you should continue to read this post, as you might find a solution to your problem.

In case the ODIN app force closes, it freezes or it shows any kind of error such as FAIL, then the root is not completed and it would be best for you to remove the phone from PC. Close ODIN, remove the phone's battery, then re-insert it after five seconds have passed and then repeat the entire tutorial once again. Eventually you should be able to apply root.

Ask for more help in comments in case you cannot complete root.

If ODIN says that the root was complete, but the phone is unable to boot in normal mode and it gets stuck at the Samsung boot animation, then you should apply a factory reset. This process will remove all contents from your device's system partition, but it will boot the Galaxy S4 in normal mode.

Here's how to apply factory reset on Galaxy S4 LTE using stock Recovery Mode:

  • power off the device completely.
  • boot stock Recovery Mode.
    - if you don't know how to do it, then use the info listed in this post here.
  • select 'wipe data/ factory reset'. Confirm.
  • when done, return to the main Recovery screen and reboot the phone.
  • wait several minutes for the boot process to complete.
  • enter your Google Account details when the rooted Android 4.3 XXUEMJ5 home screen appears.

I hope that you've managed to root your device with this tutorial. Remember that this guide triggers KNOX Flags voiding the phone's warranty.
