I bought more used iPhone x and iPhone 8,7,6 . The previous owner re-set the phones, but did not remove the device from their iCloud. It is asking me for their iCloud information when I try to set-up the phone. I don't have contact with the previous owner anymore. Is there a way to remove the device from their iCloud so I can use a new one?
Update: I have removed my iCloud using the website: http://www.BypassLock.com
