Does this help:
1. Return the phone to factory conditions.
2. Make a new apple id with a new password
3. Write it somewhere and don't lose it. Save it in a password manager. Don't forget to make a backup if it's not in the cloud.
4. Link the phone to the new apple id.
Some people choose to skip step 3. Isn't that strange?
Ok so my friend made an apple id account when i sold her a iphone 5s but she forgot what she wrote as a birthday so we tried several dated until the option disappeared,we can't use the verification by e-mail because the email is the apple id and its locked can you please help.All this happened because she had forgotten her e-mail adress.
Thanks in advance.
