One more thing, once your Galaxy S5 I9500 is on Android 5.0.1 Lollipop there is a huge possibility that you cannot revert back to Android 4.4.2 KitKat due to the secured and patched bootloader these days. So keep that in mind.
Tips: Flashed the AP image only in Odin, without the bootloader, CSC and MODEM, so you can safely revert back to Android 4.4.2 later on if you wish. In Odin’s AP button just load this file: “AP_I9500ZCUJOA3_CL3900764_QB3709712_REV00_user_low _ship.tar”.
Without overriding the 4.4.2 bootloader during the installation, you can still flashed-back any Android 4.4.2 stock firmware on-top of the I9500ZCUJOA3 Android 5.0.1 leaked version. Enjoy!
