Unable to update or restore iPad, any help?

Question

I need help to solve this problem. I can't update my iPad through iTunes. For several weeks now I've been trying it but get the same error 3194 or 3014 even after following all the troubleshooting steps. I ran iTunes diagnostics and here is the report

Answer 1

Check out this Apple article -> iTunes: Specific update-and-restore error messages and advanced troubleshooting
Errors 3000-3999 (3002, 3004, 3013, 3014, 3018, 3164, 3194, and so on): Error codes in the 3000 range generally mean that iTunes cannot contact the update server (gs.apple.com)  on ports 80 or 443. This may be because out-of-date or incorrectly configured security or firewall software is interfering, an old version of iTunes is installed, an entry in your hosts file redirecting requests to gs.apple.com (see error 1004 above), or because of your Internet proxy settings.  If you are using a proxy, try without using one or with a known-good network.  If that does not resolve the issue, follow iTunes for Windows: Troubleshooting security software issues. Error 3014 may indicate that you need to free up more disk space on the computer before trying to restore again. Error 3194 most likely indicates you do not have the latest version of iTunes installed Update to the latest version of iTunes. 
From the failed connection attempts in your iTunes diagnostics and the connection related tips in the article, it sounds like you should look at the security software on your computer and the hosts file.
