Thanks for contributing to the Apple Support Communities.
I see you're getting an 'invalid response' message when you try to connect your iPhone to iTunes. We can offer some suggestions that may take care of this.
First, update to the latest iTunes version:
Get the latest version of iTunes - Apple Support
If you continue to see the 'invalid response' message, try these steps from Get help with iOS update and restore errors. They can help even if you're not trying to update or restore your iPhone at the moment:
Check your USB connections
If you see error 4005, 4013, or 4014, learn what to do. If you see one of the errors below, you might have a USB connection issue:
- 13, 14, 1600, 1601, 1602, 1603, 1604, 1611, 1643-1650
- 2000, 2001, 2002, 2005, 2006, 2009
- An error message that includes, "invalid response"
Use these steps to see if the issue is with your USB cable, USB port, or computer. Try again after each step:
- Use the USB cable that came with your device. If you don't have it, try a different Apple USB cable.
- Switch to a different USB port on your computer. Don't plug into your keyboard.
- Plug into a different computer.
- If you still see the error, you can check for other USB issues, issues with third-party security software, and issues with hardware.
If the issue continues, contact Apple Support.
All the best.
