Remove your SD card and do a soft reset (vol down and power) and the update will start working.

you may have to try nokia software recovery tool to reset your phone completely..

My L822 got stuck on the spinning gears this morning.. Removing the SD card and reseting the phone will get the update going again.. I have helped a bunch of people do this already.
