I got the notification for the Black update sometime around the 2nd week of January here in India in my 3 months old Lumia 920. The first time the update failed due to insufficient charge in my device. When i plugged it in, the device got switched on and said that it couldn't complete the update. I have since then tried to update the device for over 40 times literally and still i stand unsuccessful ! I couldn't find an appropriate solution on the net either ! Frustrated to the extent of selling the device ! :eck: If anyone has any solution at all to this issue, do shed some light !! or will taking it to the Nokia care centre help ?
