Thought someone else may have this issue, so figured I would post.
I was trying to update to the 5.06 firmware. Click update button, get progress bar, go to 100% (maybe 99%)... but no update. Tried many times after rebooting, resetting, going through local, etc.
Turns out my wifi was not strong enough (~50% signal). I did not have an ethernet cable, so I just moved the router closer to get 90% signal and it worked.
