When trying to install ios8 on itunes it says iphone can not be updated (-1)? Any ideas?

Question

I downloaded ios8 on my itunes but when it was putting it onto the iphone it came up with an error message saying it could not be updated (-1).
It then went into recovery and when restoring it says it cannot be restored in an error message saying an unknown error occurred (3014)
Help is needed please!!
Thanks

Hello there!
It sounds like you are unable to update your iPhone to iOS 8 because of error code -1. I would start with the troubleshooting in this article first, named:
Resolve iOS update and restore errors in iTunes
http://support.apple.com/kb/TS1275
If that does not get it going again, I would use the troubleshooting for that error number from the following article:
Resolve iOS update and restore errors
http://support.apple.com/kb/TS3694#1
Check for hardware issues
Related errors: 1, 3, 10, 11, 12, 13, 14, 16, 20, 21, 23, 26, 27, 28, 29, 34, 35, 36, 37, 40, 1000, 1002, 1004, 1011, 1012, 1014, 1667, or 1669.
These errors mean that your device or computer may have a hardware issue that's preventing the update or restore from completing.
Check that your security software and settings aren't preventing your device from communicating with the Apple update server.
Then try to restore your iOS device two more times while connected with a cable, computer, and network you know are good.
Confirm that your security software and settings are allowing communication between your device and update servers.
If you still see the error message when you update or restore, contact Apple support.
Thank you for using Apple Support Communities.
All the very best,
