Should take less than 5 tops with my experience with Odin.You should see a blue bar at the bottom of the screen on your phone that shows progress. I would unplug your device, re-open Odin and start over. Sometimes there are some bugs and the application will freeze up. Your phone should show a phone and an exclamation point , its essentially soft bricked because of a bad flash. No worries, just get it back into download mode and try again! Sometimes it can take 2-3 or more tries to get it to work. Hope this helps!
