Check your hosts file
After you update iTunes to the latest version, check the hosts file to make sure your computer can contact the update server.
If you’re using a Windows computer, follow the steps in this Microsoft support article (note that resetting thehosts file will affect software services that rely on hosts file redirects). If you're using Windows on a business computer, consult your IT department to be sure applications will work correctly after you reset the hosts file.
If you're using a Mac, follow these steps:
- In the Finder, choose Applications > Utilities.
- Open Terminal.
- Enter this command and press Return:
sudo nano /private/etc/hosts - Enter the password you use to sign in to your computer and press Return. You won't see text appear in the Terminal window when you enter the password. Make sure you use a nonblank administrator password.
- Terminal will display the hosts file.
- Navigate using the arrow keys and look for an entry containing “gs.apple.com”.
- Add the # symbol and a space ("# ") to the beginning of the gs.apple.com entry.

- Press Control-O to save the file.
- Press Enter when asked for the filename and Control-X to exit the editor.
- Restart your computer.
- Try to update or restore your iOS device again.
Additionally if you have another computer that is accessible:
Restore or update on another computer
Try to restore or update on another computer with a different Internet connection. This will help rule out other issues on your computer that might stop iTunes from communicating with the update server.
Now if your iPad is locked or disabled the following Knowledge Base article will provide some valuable steps to help resolve that:
