iphone brush after prompted Apple ID incorrectly unable to unlock the iphone

1. The reason for this problem is that our mobile phone is turned on to find My iphone feature, so that when we upgrade the system activation will prompt for an Apple ID verification, this must be your own this iphone oh.

2. The above operation will also have a "look up my iPhone" then we need to enter the Apple ID to activate OH.

3. When we brush the machine or restore the factory settings, the system needs to be reactivated, and in the process of activation, the IPhone will connect with Apple's service. If the "Find My IPhone" feature in the previous ICloud is turned on, it will require us to activate with the Apple ID in ICloud.

4. If your phone is not your own and you do not know the Apple ID then you can not use the mobile phone oh, no matter what way you can not use this phone oh, if you are second-hand mobile phone we need to find the seller to give it to your Apple ID OH.
