My addle ID cannot be used to unlock my iPhone 6
My apple ID was locked for security reasons. I managed to unlock it using iCloud.com however it was still locked on my iPhone 6. I tried to restore my iPhone and now I cannot activate it. I cannot also find it at my devices on iCloud.com in spite of the fact that I bought this iPhone and it is not a second hand. Any idea on how to activate this iPhone?
iPhone 6, iOS 9.1
