Icloud accidentally locked
Hello,
I'm trying to help a good friend of mine - he forgot the APPLE ID password and accidentally locked his iPhone and ICLOUD.
I tried resetting in this link - https://iforgot.apple.com/password/verify/appleid?returnUrl=https%3A%2F%2Fwww.icloud.com%2F
But the phone number that updated in ICLOUD is an old number and we do not have that number.
Is there another way to reset ICLOUD?
If not - how do I unlock the iPhone and connect with a new APPLEID?
Thanks in advance
Yamin
