Pre-requisites

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 installed then backup data using the recovery.      

4) If the Android device powers off due to lack of battery while the installation process, it could damage the device. Therefore, the Galaxy S3 should have 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) XXUEMKC Android 4.3 Jelly Bean firmware works only on the Samsung Galaxy S3 LTE GT-I9305. As flashing this on any other variant might brick the device, verify the model number of Galaxy S3 by navigating to Settings>> About phone>> Model number

How to install I9305XXUEMKC Android 4.3 Jelly Bean on Galaxy S3 LTE

When the phone is connected successfully an Added message will appear under Odin. Also, the ID: COM box in Odin will turn blue with the COM port number, indicating successful connection

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.
