I finally got around to trying to update my wife's iPhone 4 from IOS 6 to 7.1. The update fails with The iPhone could not be updated, an unknown error occurred (3014). I tried all the suggested network diagnostics. I can ping gs.apple.com. My other iphone updates fine from the same computer. What else should I try?
iPhone 3G, iOS 6.1.6
The iPhone 3 cannot be updated to iOS 7. The oldest model that can is the iPhone 4.
Sorry.
Sorry, It is an iPhone 4, not a 3. Apparently I can't edit my original post to fix it.
I did manage to edit the original post to say 4, not 3.
Well, 3014 states:
Resolve communication issues
Related errors: 17, 1004, 1013, 1638, 3014, 3194, 3000, 3002, 3004, 3013, 3014, 3015, 3194, or 3200. These alerts refer to gs.apple.com, say "There was a problem downloading the software," or say the "device isn't eligible for the requested build."
Check the hosts file or TCP/IP filtering, which might cause communication issues between iTunes, ports, and servers.
Make sure you temporarily disable any firewall or antivirus software and try to update again.
Yes, thanks, I tried all that. As I said before, I can update my own iPhone using the same computer, just not my wife's. This is a persistent problem, it has been happening every time I try, for weeks and weeks.
