I had the same problem. It turned out that it downloaded a bit, then basically did that whole "download the rest as you boot up the game" bit in the background before finally finishing everything up, which meant that it looked "stuck" and took ages. But it eventually finished and I could play the updated game.
Same here. I've restarted the download numerous times and the device as well, it still won't complete the update.
Same here. I've restarted the download numerous times and the device as well, it still won't complete the update. Just wait longer. Ignore the 100% wait long enough (and I really mean give it a good 5mins after 100%) and it'll finish up
Mine still won't load up. It's just stuck at 100% for the past half hour or so...
