The (iPhone/iPod/iPad) "XXXXXX" cannot be restored at this time because the iPhone software update server could not be contacted or is temporarily unavailable.

If you want to upgrade or downgrade the baseband, make sure you didn't change the hosts file to add the Cydia Server. Cydia cannot handle the requests for the baseband certificates. Maybe you tried to use SAM Activation method.

There was a problem downloading the software for the (iPhone/iPod/iPad) “XXXXXXX” the network connection was reset, make sure your network settings are correct and your network connection is active, or try again later.

You need to disable both your Anti-Virus and your windows/security firewall in order for the update/restore to go through.
