Yes I've tried all of those.
Last 3 of the 4 tries I did were on WiFi and on charger the whole time. The package was downloaded without error. The error show up at the spinning cog screen.
Are there any other user who experience this as well?
Well, I might just do that. But, still, I'd really like to know as to why is this happening. I've read that some people have got the update working on their 620s.
