Samsung has recently rolled out its newest stability update via Android 4.3 XXUEMKE Jelly Bean firmware for Galaxy S4 (LTE) I9505.

The new stability update also features bug-fixes for the most common issues reported till date with official Android 4.3 firmware.

Those who have already updated their device to Android 4.3 XXUEMKE official firmware can now root the same via Odin flash tool using CF-Auto-Root by following this guide.

CF-Auto-Root tool is ideal for beginners who are rooting for the first time and it works well with stock firmware.

How CF-Auto-Root Works

It first flashes the modified (custom) recovery and cache partition for installing just the SuperSU (super user) access and then erases the cache partition for re-flashing the stock recovery.

NOTE: Rooting is essential to gain full system access to the device for installing third-party root apps, popular custom ROMs and latest system tweaks for enhanced performance. Rooting any device will increase its flash counter (from 0 to 1) and void its hardware warranty.

You can however restore the device warranty by configuring Triangle Away app (download from Google Play Store) to reset the counter (from 1 to 0) or by reinstalling the latest official firmware.

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


    • The CF-Auto-Root package and instructions provided in this guide are meant for Galaxy S4 (LTE) I9505 model only. Do not attempt using this procedure on any other model, as you may inadvertently brick or damage the device.
    • Ensure the device is factory unlocked (carrier SIM unlocked) with CWM or TWRP recovery installed on it.
    • Verify that the phone's bootloader is also unlocked.
    • Back up important data and settings on the phone via one of the custom recovery tools such as CWM or TWRP to prevent data loss during firmware installation.
    • Ensure the device has at least 80% battery charge to prevent unexpected device shutdown (due to battery drain) during firmware installation.
    • Enable USB Debugging mode by navigating to Settings > Developer Options.
