It asked me to restart and try again. I tried and I also unplugged the power but it didn't help. I don't want to reset, is it any advise to update to 5.1.1? Thanks
Problem solved. It's a small bug that it cannot be updated with ethernet connection. It works with WIFI only.
I was able to get the upgrade to work with Ethernet. It did take almost 2 hours after the download that only took about 1 min.
I also was able to complete the download after removing the Ethernet cable and connecting via wireless to my router. This also fixed my problem of not being able to view my Photo Stream
