iOs 11.4 iCloud Activation Lock Removal in 3 min

This method still works for all iPhones and iPads.

SUMMARY: Do you have your iCloud locked? If your iPhone has an iCloud lock on it, it means that regardless of how much you paid for your second-hand phone, the previous owner can still block you from using it. They can do this by keeping the device locked to their iCloud account and not allowing you to log into the phone.
