Steps to Update Galaxy S4 LTE I9505 with Android 4.3 XXUEML9 Jelly Bean Firmware

Step 1: Extract Firmware zip file via WinRAR/7-Zip or WinZip to obtain a .tar.md5 file and some other optional files.

Step 3: Power off the Galaxy S4 LTE and boot the device into Download Mode. To do so, press and hold Volume Down and Home buttons together until a construction Android robot icon with a warning triangle appears on screen. Then keep tapping Power button to progress into Download Mode.
Step 5: Launch Odin on computer as an Administrator.
Step 6: Connect Galaxy S4 to computer via USB cable while it is still in Download Mode. When Odin detects the device and a pop-up message implying successful connection appears on screen, the ID: COM box will turn yellow with the COM port number.

Step 10: After the firmware is installed, a PASS message with green background appears in the left-most box at the top of Odin. The phone will then reboot to the Home screen. It is now safe to disconnect the USB cable and remove the phone from computer.
