n85 won't turn on

I was updating the firmware on my nokia n85 when half way through the installation, my computer decided to shut down the nokia ovi suit thus leaving my phone blank. Now I try to turn it on it vibrates once and thats it. No backlight display of any kind, or anything. I've tried different batteries, removing everything, plugging it into my computer and nothing will work. I was lucky enough to back everything up but it's worthless without a working phone. Any help please would be more than greatful.
