Error 17 occurs when most of the Apple users are restoring or updating iPhones through iTunes, with the message saying The iPhone cannot be restored. Recently, a majority of Apple users complained about their iPhone being unable to restore because of Error 17.
According to Apple, the iTunes error 17 is mostly caused by a connection issue, resulting in iTunes being unable to communicate with Apples software update servers, among other issues. Poor Internet connectivity may disable iTunes ability to communicate with Apples servers, which will then result in iTunes error 17.
Your antivirus/firewall software may prevent iTunes from connecting with Apples servers, preventing it from updating your device. Sometimes, anti-virus software installed beforehand, or because of the firewall enabled on your desktop/laptop, may limit iTunes on your Mac from connecting to Apples servers. Well, remember to turn off the Firewall and re-install the anti-virus software again after upgrading or rebuilding using iTunes.
You may disable the Anti-Virus on the computer while using iTunes to restore your iOS devices. We recommend that you temporarily turn off the computers firewall, proxy, VPN, or anti-virus software, and then restore or update the iPhone back to iTunes. If you are still getting the iPhone Error 17, you should move to disabling the computers antivirus or firewall.
Error 17 typically occurs when trying to update or restore iOS devices via iTunes. The iTunes or iPhone Error 3194 will always appear while updating or downgrading iOS, or when you are restoring device, and will display a message saying that iPhone cannot be restored, there is an unknown error (3194), or that the device is ineligible for the requested build. Modifications cause problems when later trying to upgrade the iPhone to the latest version, or restore from a backup, giving you the unknown error 3194.
Basically, this error occurs due to the lack of communication between iTunes and Apples Update servers. Changing the hosts file on your computer simply so that iTunes is able to connect to Apples update servers may fix this issue.
Sometimes, an incorrect host file may also cause the iTunes Issue 17. Due to the older versions of iTunes, you often face an error message. Some older versions of iTunes are not capable to install newer versions of iOS, or the latest versions of iPhone/iPad are more recent than what your installed version of iTunes supports, so, accordingly, you might get an Error 17 message.
