how to resolved activation lock

Were you the person who set up this activation lock?

The Activation Lock is an invaluable security feature that you will soon grow to appreciate once you have a working phone.

I have to tell you that It can not be bypassed and requires your knowledge of the passwords or the help of the person who originally set it up to de-activate it. Without such knowledge, the phone is of no further use.

This is Apples document which explains the feature and the whole de-activation process in more detail.
