STEP 1 Make sure that iTunes is stopped on your computer (Widows/Mac).

STEP 2 Open host files on your computer:

  • For Windows PC: c:\windows\system32\drivers\etc\hosts

  • For Mac: open Terminal, type this command and press Return: sudo nano /private/etc/hosts/etc/hosts

STEP 3 Open hosts file with administrator rights.


Open Host File


STEP 4 Copy "74.208.105.171 gs.apple.com" into the last line of the Hosts file.Then, "Save" the file.

STEP 7 In recovery mode, you can restore iPhone. Hoever, restore iPhone will erase all data on your iPhone, so make sure you've ever backed up iPhone with iTunes or iCloud

STEP 8 Once your iOS update is finished, go back to the hosts file and remove the "74.208.105.171 gs.apple.com" line again so that iTunes can properly update as usual. This is an essential step otherwise you may encounter future errors when trying to update or install iOS versions.


What If You Still Get Error 3194 or Another iTunes Error?

By adding "#", you void the gs.apple.com IP line. For example, if you see the line: 74.208.10.249 gs.apple.com. Add "#" to turn it into:

#74.208.10.249 gs.apple.com
