I swapped out devices yesterday due to a sticking home button. Started my restore around 6pm and it would usually take a couple hours max to finish. Only populated about 25% of my pictures. Shows the spot for the pic but not the actual pic or video. I erased all and restarted the restore to see if that would help it finish. From 8pm last night until 7:30 this morning it's still saying "downloading" under my camera roll. All other parts of the restore are complete. What else could I try to fix this?
