Step 2: Connect your device to PC.

You device should automatically be recognized by Odin. At the lower-left of Odin interface, it should show a message that says "Added!" and in the meantime you should see a light-blue box at the ID:COM section stating "COM:3" (the number depend on which USB port you have plugged the device cable and is irrelevant).

Step 3: Click "PDA" or "AP" to add tar.md5 file that you have extracted and then click "Start".

   WARNING: 

DO NOT REMOVE OR OPERATE ON YOUR DEVICE UNTIL THE OPERATION IS FINISHED OR FAILED IS SHOWED ON ODIN.

A Firmware may contain 4files instead of 1file:

• BL stands for bootloader
• AP represents the system partition (possibly stands for Android partition); under previous Odin versions, this was called "PDA"
• CP represents your modem/phone
• CSC stands for Consumer Software Customization, this specifies the features your Android device gets according to its geographical location and carrier.

When the flashing process is done and if everything goes well, you should see a big green box saying "RESET" or "PASSED" (depending on the version of used Odin). By now, the device reboot and it is safe to remove/unplug your device.

  Flash Process Succeeded.
