When updating or restoring an iPhone, iPad, or iPod touch through iTunes, you may encounter error messages such as “This device is not eligible for the requested build” or Error 3194. These error messages occur when iTunes is unable to connect to Apple’s software update servers. This article provides multiple solutions to help fix error 3194, error 17, and “This device is not eligible for the requested build” on both Mac and PC.
1. Update iTunes
Updating iTunes to the latest version can often solve the issue. On a Mac, go to iTunes > Check for updates. On a PC, click Help > Check for Updates. After updating iTunes, try to restore or update your device again to see if the issue is resolved.
2. Check Internet Connection and Router
Ensure that your internet connection is working correctly by troubleshooting your network preferences on a Mac or checking the network settings on a PC. Also, check if your router is blocking access to Apple’s servers. Try bypassing the router and connecting to your modem directly using an Ethernet cable. Restart the modem and your computer and then try to restore or update your device again.
3. Disable Security Software
Security software may be blocking your computer’s connection with Apple’s servers. Try disabling your antivirus, firewall, or any other security software temporarily to update your device. If the issue is resolved, try adjusting the settings of your security software or reinstalling it.
4. Check the Hosts File
Check the hosts file for any problematic entries. On a Mac, open Terminal and type “sudo nano /private/etc/hosts”. When prompted, enter your system password and press Return. Look for “gs.apple.com” in one of the entries and add a hashtag (#) and a space to the beginning of that item. Press Control-O to save, and then restart your Mac. On a PC, follow the advice given on the Microsoft support website to reset the hosts file back to the default. Try restoring or updating your device again to see if the issue is resolved.
5. Restore or Update from Another Computer
If none of the above solutions work, try using a different computer on a different network and internet connection. The issue may be related to the network settings or firewall of the original computer.
