How to Root Galaxy S4
If you need to Root your Samsung Galaxy S4 I9500 which is running the official Android 4.4.2 KitKat XXUFNG1 OS, you will need ChainFire rooting toolkit, a computer and the ODIN flash tool.
Prerequisites to ensure the right function and usage of the app:
1. This rooting procedure should be used only for a Samsung Galaxy S4 I9500 with firmware version XXUFNG1 ONLY.
2. Create a manual backup of all data files (the most trusted data backup app) and personal settings stored on Galaxy S4 before rooting the device.
3. Battery level must be at least 50 per cent to avoid power interruption during the installation.
4. Enable USB debugging mode on the Galaxy S4 smartphone.
5. Download and install the necessary USB drivers for the handset on the computer.
6. Download ChainFire's Auto-Root tool for Android 4.4.2 KitKat to the computer.
7. Download the ODIN flash tool to the computer.
Remember that the app may malfunction or access smartphone data that may be personal, or fail to work. Any Rooting you do is at your own risk. You should however read and follow all instructions carefully to avoid damaging the device. Root access also trips the Samsung Knox and voids any active warranty, so you should consider doing at your own risk.
Process for Gaining Root Access:
1. Extract the ODIN flash tool executable file and ChainFire's Auto-Root to an easy access location on the computer.

3. Launch the ODIN flash tool executable file on the computer.
4. Connect the smartphone using a USB cable and check if the ID:COM on the ODIN flash tool turns yellow. If not, install the necessary USB drivers as mentioned above.
5. On the ODIN flash tool, click on PDA then select the file "CF-Auto-Root-ja3g-ja3gxx-gti9500.zip."
6. Check the AUTO REBOOT and F.RESET TIME on the ODIN flash tool.
7. Hit the START button to begin installation process.
8. During the rooting process, the smartphone will reboot automatically into Recovery Mode to install the necessary files and the ID:COM should turn green.
9. Once the installation process has been completed, it should reboot automatically which may take up to five minutes before reaching the home screen.
10. After the device has reached the home screen, it can now be disconnected from the computer.
11. Check the root access status of the device by downloading the Root Checker app at the Google Play Store.
