Can't turn off Find My iPhone
I have updated my phone to a 6s and want to give my iphone 5s to my son.
When I am trying to resore my iphone 5s it won't let me turn off find my iphone. It requests my apple password but when I input this the screen just shakes and the password is not accepted.
I did have to change my password when updating to my iphone 6s but I know I am using the correct password as I can sign into my account without a problem.
Help!!
iPhone 5s, iOS 9.0.2
