  • use this post only with the Samsung Galaxy S4 LTE model number I9505.
    - do not try to root any other Galaxy S4 device, as you will end up bricking its firmware.
  • don't attempt to root any other Android devices with the files that you will find in this post.
  • download and install the Samsung USB Drivers for your Galaxy S4 LTE from here.
    - install the drivers on your Windows computer.
  • disable any antivirus app from running on your PC.
  • disable the Samsung KIES software too.
    - KIES will block ODIN and the root process. > Odin is the app we will use to flash the root file.
  • enable the USB Debugging option from the Developer Options menu.
    - if Developer Options is hidden, then you need to go to Settings, More > About Device and then tap 7 times on the Build Number section.
    - Developer Options will appear in Settings now and you can enable USB Debugging.
  • make sure that your phone's battery charge level is over 50%, so that the device won't switch off in the middle of the rooting process.
  • this guide is for advanced Android users, do not blame us in case you lose any important data or brick the device.
