An Invalid Response Received From the Device, Fix

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 iOS devices to their computers. Furthermore, some other users have stated that iTunes freezes while they are syncing their iOS devices with their computer.

This error occurs when the USB communication to your iOS device is broken.

I experienced this problem also. I have recently purchased an iPhone 7. 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 iOS device
• update or restore your iOS device
