Several users have reported that they received the “iTunes could not connect to iPhone or iPad because an invalid response was received from the device” error message when they connect their iPhone to their computers. Furthermore, some other users have stated that iTunes freezes while they are syncing their iPhone with their computer.
This error occurs when the USB communication to your iPhone 18 Pro is broken.
I experienced this problem also. I have recently purchased an iPhone 18 Pro. After connecting it to my computer, I received this error.
With iTunes you can:
- sync your content (movies, apps etc)
- move (add or remove) the content from your computer to your iPhone
- update or restore your iPhone

- Try a different USB cable

- On your iPhone, try resetting your network settings by going to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings (note that this will remove your Wi-Fi passwords etc).
- A third party security program may be causing this. Because it may prevent iTunes from communicating to Apple servers. Update your security software. If possible, try disabling it temporarily.
- For Windows, reset TCP/IP.
- On your iPhone, go to Settings > General > Date & Time and turn on “Set Time Automatically”
- On your Mac (if you are using a Mac), make sure that time and date settings are set correctly (System Settings). If you are using a PC, also make sure that time and date settings are set correctly.
