Odin flashing Procedures:

1) Extract or unzip the downloaded firmware, Odin flasher program can’t read it until you’ll get the correct file path which is in (.tar) file format. You can use ‘7zip’ or ‘winrar’ to do that task,  I used winrar.

2) Run Odin Downloader v3.07 flasher program.
3) Do Not check the Re-Partition checkbox. Mark check these checkboxes Auto Reboot and F-Reset Time and nothing else.
4) Reboot the phone in download mode: To reboot the Galaxy S4 into download mode , you need to turn the power off. After it completely shut down, just press and hold the Volume Down key, Home button and the Power ON/OFF button simultaneously.
