Step 4 - Launch ODIN on computer and connect your phone to it while the phone is still in Download Mode.

Step 10 – Finally, when the home screen boots up, just disconnect your phone from computer.

NOTE: In case the device fails to boot into Recovery Mode automatically (as given in Step 10) or cannot root your device, repeat the entire procedure again.
