thanks a lot yaar. i was very depressed for the last 5 days dat the best feature of my mobile (n73 which i own for almost last 2.5 years) suddenly got some problem and showed that hardware failure tag. I almost had decided to go to nokia care tomorrow, but suddenly today evening it cliced in my head to search the problem statement on net, and i got ur solution which really clicked for me. Now my mobile camera has become completely ok, thanx a lot again buddy.
This is because of problem with mem card, just take out card and start your camera, after cam is on put the card back. I think it will work, at least for me it worked. I think video cam may not work, use still cam.
