Im running iOS9 on my iPhone. I did a backup using iTunes. I did a reset of contents and settings on the iPhone and now that im trying to Restore using the iTunes backup i created, i get this msg. The iPhone, although i can see, that it goes into a screen saying Restoring in Progress it suddenly ends and i get the msg attached in iTunes. Its strange because my 500GB drive has 170GB free space! After all this the iPhone reboots without any progress.
