I saw today that an update was available so I connected to my WiFi then waited for it to download but after 1 hour or so it was still 0%. So I tried a soft reset but it didn't work. a solution will be much appreciated. Thank you
I'm having the same issue... it's been downloading for over a day now, and I seem to be stuck at 2%. I've allready restarted my lumia 640, but it's still stuck at 2%
I ended up downgrading back to WP8.1 with the Windows Phone Recovery Tool. After that I reinstalled the Insider app and upgraded to 10166 without any problem. I'm running it now. It took an hour and a half in total. It may take longer depending on your internet speed. Also, it only downloads over wi-fi
I hoped I could help. Just let me know if it worked for you too
