If you are unable to restore from a backup, the backup file may have been corrupted by the email service used to send it.
Please send the CSV file again with a different email address, or by another method, so that your new iPhone can receive it, and then try the restore once more.
If it still does not work, please contact us from the Contact Us button in the upper right.
Attaching your backup file to your message will help us find the cause faster. Thank you for your cooperation.
