Odin needs to see the phone to go green. Uninstall the samsung modem and the other driver. These drivers you can get only when phone is connected to computer in download mode. Than you can delete the driver, restart the computer, install driver and move further. Also don't connect the phone while odin is running cause you might have problems in working with it further, meaning that it can break the driver installed in windows which will take you back to the step mentioned before.
If you still have problems, contact me.
Good luck !
