Root Galaxy S4 LTE I9505 on Android 4.3 XXUEMJ5 Official Firmware [GUIDE]
Root Galaxy S4 LTE I9505 on Android 4.3 XXUEMJ5 Official Firmware via CF-Auto-Root

Samsung recently rolled out its latest Android 4.3 (Jelly Bean) official update for Galaxy S4 (LTE) GT-I9505 users in Europe. The new firmware can now be easily rooted via CF-Auto-Root tool by XDA developer, Chainfire.

Users who are rooting their device using this tool should note that Samsung's KNOX security system will get activated once the Galaxy S4 is rooted, and it cannot be reset or erased. In other words, this could void the warranty on the device, as the flash counter on the device will change from 0 to 1 after rooting.

IBTimes UK will not be held liable for any device damage during or after firmware installation. Users are advised to proceed at their own risk.

Pre-Requisites

  • This guide and the given rooting tool are meant for Galaxy S4 LTE I9505 model only. Do not attempt this procedure on any other device, as it may inadvertently damage or brick the device. Verify the device model number by navigating to Settings > About Phone.
  • Backup your important data and settings on the phone to prevent data loss during root installation.
  • Ensure the correct USB drivers are installed for the phone on computer (download Galaxy S4 LTE I9505 USB drivers).
  • Make sure that the phone has at least 80% battery charge before you begin.
  • Disable Samsung KIES as well as any security software installed on the computer.

Downloads Required

NOTE: Backup important files on the phone's SD card, so if you perform a data wipe or factory reset on your device via recovery (which also formats the SD card), the data may be restored after rooting the device.
