Error 3194 while restoring jailbroken iPod touch 4g
Make sure that all Apple-related entries are removed from your hosts file in C:\Windows\System32\drivers\etc\hosts, then put the device in DFU mode and restore it.


Connect the device to your computer and turn it off.
Hold the power button and the home button together for 10 seconds, then release the power button but keep holding the home button.
Keep holding home further and a message should appear in iTunes telling you that the connected device must be restored.
