Can the iCloud lock be broken?

The following solutions are not an advice for people who have stolen an iPhone but for the ones that bought a stolen one from an online shop and the iCloud Activation Lock is enabled.

1. First of all you should always check the IMEI number of a used iPhone before you buy it with an iPhone IMEI Check Service by proven and legitimate providers like UnlockSpector.
2. The best way to remove iCloud activation Lock is by contacting the original owner of that iPhone. But the problem is that in most cases, the seller of a second-hand iPhone from an e-shop usually isn’t the original iPhone owner. You can use services that have access to Apple’s iCloud databases. This allows you to get a report with all the contact information from the original owner. With that information you are able to contact the original owner, explain the situation, and ask him to remove the iCloud Lock of that iPhone via iCloud. One of the most trustful and of cource legitimate provider of such services is iPhoneUnlock.Zone.
3. Getting the contact information of the original owner is the safest and the only legal way to remove iCloud Activation Lock from your iPhone. If he refuses to unlock it you can now be able to send a formal iCloud Removal request to Apple. (because you have the Apple ID of that iPhone)
4. Having the Apple ID of the original owner, can help you to remove the iCloud Lock by submitting it to an iCloud Activation Screen Removal service, again by iPhoneUnlock.Zone.

This is how I managed to unlock mine when I got scammed and bought a second-hand iCloud Locked iPhone 7. In general, contacting the previous owner is the best way to remove iCloud activation lock from iPhone.
