I have to say, that I am so glad I am not the only one with this problem. I did the exact same thing (update the firmware), and the camera, which up to that point had been working like a champ, totally bricked on me. It flashes an orange light in the front, solid blue in the back, and is totally unresponsive to resets (power on, power off, on my knees praying, etc., etc.....)
So, I will call D-Link, and hope for a refund. What a shame, I wish they had another way to resucitate the thing, I hate to go through all of this (begging, and then mailing, waiting, reinstalling....arghhh)
Thank you guys for your posts, I dont feel that unlucky or stupid now.
