Q: Dear Apple Support,  Please do the needful of my Iphone5 Black/Negro, 64 GB Part no. FD642E/A, Serial No. DQ*******H1G because until now I cannot update the IOS 9.1 almost two months from now.  Thank you very much for you assistance.  Regards,  Lanie

Unfortunately, we are not Apple support - these forums are for users helping other users like you.

So, you say that you cannot update your iPhone to the latest iOS?

What steps have you tried?

FYI, I have asked the hosts to remove your serial number - it is best not to publish sensitive information on an open online forum.

Get help with iOS update and restore errors - Apple Support

Check for hardware issues

Errors: 1, 3, 11, 12, 13, 14, 16, 20, 21, 23, 26, 27, 28, 29, 34, 35, 36, 37, 40, 53, 56, 1002, 1004, 1011, 1012, 1014, 1667, or 1669.

Your device or computer might have a hardware issue that stops the update or restore from completing.

1. Check that your security software and settings aren't blocking your device from communicating with the Apple update server.
2. Then try to restore your iOS device two more times while connected with a cable, computer, and network you know are good.
3. Make sure that your security software and settings are allowing communication between your device and update servers.
4. If you still see the error message when you update or restore, contact Apple support.

If you still see the error message, check for outdated or modified software.

Make an appointment at the nearest Apple store to have your iPhone evaluated.

Once the diagnostics are complete, the staff will explain your options.
