This typically happens because you've jailbroken your device in the past and have changed the way iTunes connects to the verification server. You can fix this by editing your hosts file. You can also perform a remote factory reset of your device to get it working again. Steps Part 1 Editing Your Hosts File 1 Quit iTunes. Make sure iTunes is completely closed before proceeding so that the changes you make take effect. 2 Open the hosts file on the computer. Error 3194 most often appears when you are trying to update or restore your iOS device through iTunes, and iTunes cannot connect to the Apple verification servers. This is common if you have jailbroken your device in the past or are trying to downgrade iOS. Windows - Navigate to C:\Windows\System32\drivers\etc and double-click the hosts file. Select "Notepad" from the list of available programs. Mac - Open the Terminal from the Utilities folder, type sudo nano /etc/hosts, and press ⏎ Return. This will open the hosts file in a text editor. 3 Find the bottom of the hosts file. You'll be looking for an Apple address at the bottom. A standard hosts file will not have any lines without a # at the front. 4 Look for a .74.208.105.171 gs.apple.com entry. This redirects the signature verification process to the Cydia servers.[1] It is the presence or lack of this redirection that is causing the error. What you do next depends on whether or not you can find this line: If you have 74.208.105.171 gs.apple.com at the bottom of the file, add a # to the front. If you don't have the line, add 74.208.105.171 gs.apple.com to the bottom of the hosts file. 5 Save your changes. This should allow your iPhone to make the connection properly.[2] Windows - Click the File menu and select "Save." Mac - Press Ctrl+O to save and Ctrl+X to quit. 6 Open iTunes and attempt your restore or update again. In many cases, the changes you made to your hosts file should allow you to proceed. Note: If you're trying to downgrade to a previous version, it may not be possible with the version of the firmware you have downloaded. Try a normal restore using the firmware downloaded directly through iTunes. 7 Put your iOS device in
