Error 4000 is an undocumented error code (at least publicly undocumented). It means that the connection between the phone and iTunes was interrupted in the middle of a sync or update activity. In the past this might have been caused by a flakey USB port, an antivirus or a firewall.

So first check your antivirus and firewall (temporarily disable them), but if that doesn’t fix it there are three workarounds for the bug:
Note that this error should only be a problem for updates; if you are restoring iOS rather than updating it should not occur.
