Q: New iPhone 6s iTunes says "serial number: n/a"
So I finally got my new 6s last week but after a trip to visit family during the weekend and midterms at my university this week, I finally got to work on switching from my iPhone 5 (running on like iOS 6) to my new 6s. I backed it up via iCloud and through my laptop. Then when I started switching to the 6s, like other users my phone would freeze up on the white "slide to upgrade" screen and tried running the update/refresh. I then decided to do it through my computer (took multiple tries due to lost connections) but I finally got it. Once I would start the process of putting it onto my new phone (such as when it says "extracting software") it shows the phone's serial number, but when it goes to "preparing iphone for software update" the serial number changes to "n/a". Once I start the update and it says "serial number: n/a" it starts prepinng my phone and updating it, the bar on my phone stops at about halfway (during "updating firmware" I believe) I then get an error message from iTunes on my laptop saying " The iPhone could not be updated. An unknown error occurred (1)." Anyone know what is causing this? Any way to fix it or tips/ideas? I talked to Apple support this morning and tried what they recommended (checked to make sure itunes and os were up to date, turned computer and itunes off and on, tried different USB slots and different charging
iPhone 6s, null

See: Get help with iOS update and restore errors - Apple Support, specifically this section:
Check for hardware issues

Your device or computer might have a hardware issue that stops the update or restore from completing.
- Check that your security software and settings aren't blocking 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.
- Make sure 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.
If you still see the error message, check for outdated or modified software.
