Once you already reboot the phone in download mode, simply connect the phone to your PC. In Odin window – the ID:COM box will turn to blue color and indicates the COM port number and a message says “Added” on a log cat box will prompt you that the device is already detected or recognized by Odin. Your COM port number might be different from mine. If you do not see a COM port number then there’s something missing or wrong. You may read again from the top of this post.

The stock firmware is packed in a single .tar.md5 file only. Simply click on the AP button, then browse to the folder where the file you have previously extracted and then select and load it.

Once if all set and ready to fire-up, hit the “START” button in Odin to begin flashing the stock ROM. Do not ever interrupt the phone while already in flashing progress, like disconnecting the cable or turning off the device. Just wait until it completely finishes.
Wait until you see the PASS!! message.
When the Stock Firmware installation successfully completes, you will then see a word “PASS” in Odin. This indicates that the flashing already finishes, and on the log box it says “All threads completed (succeed 1 / failed 0)”. The phone will just then automatically reboot, then it’s about time to remove it from PC or laptop USB connection.
