I have never rooted my phone and I am not that interested in rooting, when I saw the new ICS 4.0.4 leak I thought my wait is over, however, I am having difficulty putting my phone into "download mode'' in order to use Odin program. When I push volume up+volume down+power, it takes me to unlock bootloader page. I have tried this so many times, taking out the battery, doing it while connected to usb or not, other combinations of keys, and nothing works. I also spent more than an hour searching forums and google searched, but couldn't find a solution. I would appreciate it if someone can help me out.
