let me Bing that for you

Installing and troubleshooting problems during the software update for Windows Phone 7

You popped error code 801812C1. I just Binged that number and the 2nd result was to the official MS page for error codes. If you click on the "Show solution" it brings up a really detailed set of instructions you should look over and report back when done!!
