There is hope. I got this error when my Fierce XL went to restart. 6 times I tried with the same error. On the seventh time it restarted fine and updated! Persistence pays off. I noticed all the times I got the error I let the screen time out. The last time I made sure all apps were closed, the update page stayed open and kept touching the screen making sure it did not time out. Then it came up with no error and hard the restart button. Tapped restart and it updated fine. Might not work for you but it's worth a try.
