What happens when you try and update? I had my dinc for a long time where when I'd receive the update. I'd click install, it would count down the 10 seconds or so and.....nothing, every time it would do that. I did end up finding a solution for myself in which I reboot into recovery and 'wipe cache partition'. It worked for me, may for you.
We do need to see what is happening with your update.
What happens when you attempt to load to software update to your phone? Is there an error message?

Mine does the same thing. Counts down 10 seconds, and then just stops. Eventually, I get a screen that just says, "Ok. Cancel." It's happened more times than I can count and I haven't been able to get to a Verizon store to ask them for help.
