Q: HELP MY APPLE ID IS NOT DETECTED FOR SETTING UP

Hi, yehey123.  

Thank you for visiting Apple Support Communities.  

I understand you are unable to restore your new iPhone from your most recent backup.  The usual cause for this is that the backup was created with a newer iOS version.  I would recommend taking a look at the article below on how to resolve this issue.  

If restoring from an iTunes or iCloud backup requires a newer version of iOS

Also, be sure to verify that the backup you are attempting to access isn't attached to another Apple ID.
