Hello, I'm upgrading to Windows Phone 8.1 developer preview on my Lumia 920. And my phone got stuck at bootscreen (which just shows "NOKIA") for over 50 minutes already. Wonder what to do next - any ideas? Thank you!
I resolved the problem by pressing power + volume down + photo buttons for a few seconds. After this it restarted and continued installation. WP 8.1 is awesome
Thanks for the guidance, it is working now after pressing the power key and the volume lower buttons for almost 30 sec., I've tried for my Windows Phone Nokia Lumia 925 with Windows 8.1
