iPhone Locked to Owner - Can't get to the screen to enter Apple ID
I bought and refurbished iPhone 11 for a relative of a family member but after a couple days of use it stopped getting 4G to the point we couldn't go into the celular menu inside of settings and updating was not working either. We them decide to try to restore the iPhone using a computer and after updating to the latest version of iOS in hopes that it would fix the issue the phone showed the message Phone locked to owner and we could not get to the screen to enter the Apple ID and the only option available after connecting to Wi-Fi was to turn the phone off. We them remove the phone from his iCloud but so that locked to owner would disappear but to our surprise it is still having the same weird issue where once we restart the phone it shows locked to owner with the first characters of his Apple ID and we can't get to the screen to enter the email and password, only seeing and option to turn off the phone where it we would expect to be prompted to enter his Apple ID and password. We even try to put the phone in DFU mode and restore that way but the issue still persists we can't get to the screen to enter the Apple ID. Has anyone face that before and how did you solve it?
