Q: I can't restore my iphone 5 error 3194

You are not addressing Apple. This is a user to user support forum. See this support document for information regarding the error 3194. If you see Error 3194, Error 17, or 'This device isn't eligible for the requested build' in iTunes - Apple Support

If you have already tried all of the steps mentioned in the support document since I provided it, then you need to make an appointment at the Genius Bar of the nearest Apple Store for help.

Then use this to find out how to reach Apple in your country. Contact Apple for support and service - Apple Support
