IBTimes UK reminds its readers that it will not be held liable for any damage to the device. Before installing the official firmware, users are advised to verify that their devices meet following requirements.

2) Enable USB Debugging Mode on phone to connect it with computer and use Android SDK with it. [Press Menu>> Settings>> Applications. From there navigate and click on Development option and then check the USB Debugging Mode.]
3) As the tutorial is likely to wipe all data of the phone, create a backup. If the device is having any custom recoveries such as CWM/TWRP already installed then backup data using the recovery.
4) The Galaxy S4 should have charge above 80% battery charge.
5) The device should be factory unlocked and not locked to a particular carrier.
6) The phone will lose custom ROM with the installation of official firmware. Additionally, the custom recovery such as ClockworkMod/TWRP will be replaced by stock recovery.
7) The device will no longer belong to a rooted version with the installation of official firmware.
8) XXUEMJ7 Android 4.3 Jelly Bean firmware works only on Samsung Galaxy S4 LTE GT-I9505. As flashing this on any other variant might brick the device, verify the model number of Galaxy S4 by navigating to Settings>> About device>> Model number.

Note: If the Added message does not come then try another USB port, try the one located at the back side of the computer. If Odin still fails to recognise the device then re-install USB driver.

How to fix bootloop issue
After flashing the firmware, if the Galaxy S4 come across any issues such as boot animation or bootloop (after step-11) then place the device into recovery mode by pressing and holding Home, Power and Volume Up buttons together. In recovery mode, perform data wiping task by selecting Wipe data/factory reset. Then select Wipe Cache Partition and once the action is completed, reboot the phone by selecting reboot system now. In recovery mode, use Volume keys to scroll between options and Power button to select the desired option. It should be noted that performing wiping task will erase the phone's internal memory data.
