How to fix error 3194 when restoring an iPhone

Depending on the needs of use, users can restore the  iPhone  as desired. However, during the restore, the user may unfortunately get error 3194. The following article will guide you on how to fix error 3194 quickly and simply.

Some causes of error 3194 after restoring iPhone:

1. Connection between devices has occurred.
2. iTunes is blocked by your computer and cannot download updates.
3. iTunes fails to connect to Apple 's software update servers,   or the iOS version has expired and is no longer supported.

1. Check the connection between the devices

To restore or update the iPhone, the user must connect  the phone  to  the computer  via iTunes. If you get error 3194 in the process, you should double check the connection between the two devices to make sure the connection is still stable, then try to restore or update again.

2. Check network connection

Error 3194 is usually caused by a network issue. Therefore, you need to ensure that the network connection you are using is not interrupted. Updating or restoring an iPhone should be done in a place with a stable and open connection. You can try again by:

- Restart the computer and modem.

- If you are using Wi-Fi, try connecting directly to the modem via Ethernet to confirm that the problem is not with Wi-Fi.

3. Verify the Firmware

If you get the message " This device isn't eligible for the requested build " then that means that the iOS downgrade update you are doing has been unsubscribed by Apple.

For example , Apple just released iOS 14 (in 2020) and stopped registering iOS 13.7 or less about a week later. Therefore, when you try to downgrade your device back to iOS 13.7 or lower, you will get an error.

Therefore, you need to check the  firmware  first to make sure the update is not interrupted while restoring iPhone.
