Thank you for visiting Apple Support Communities.
I understand that you are receiving an error 6 when attempting to update or restore your iOS device. Here are the troubleshooting steps that I would go through for that specific error.
Check your security software
Errors: 2, 4, 6, 9, 1611, 9006.
Sometimes security software can stop your device from communicating with either the Apple update server or with your device.
Check your security software and settings to make sure that they aren't blocking a connection to the Apple servers.
If you still see the error message, check for USB connection issues.
