Software server could not be contacted. Server does not support this version of itunes.

Just what error message(s) are you getting?

Update Server

Try:

- Powering off and then back on your router.

- iTunes for Windows: iTunes cannot contact the iPhone, iPad, or iPod software update server

- Change the DNS to either Google's or Open DNS servers

Public DNS — Google Developers

OpenDNS IP Addresses

- For one user uninstalling/reinstalling iTunes resolved the problem

- Try on another computer/network

- Wait if it is an Apple problem

or maybe:

iOS: Restore error 3194 or 'This device isn't eligible for the requested build'
