iPhone 6S plus wont connect to iTunes "Invalid response".

I'm running OSX 10.7 on an older macbook 4,1, and iTunes is on 12.2 and my iPhone is on IOS 10. Every time I plug my phone into my laptop I get the message "iTunes could not connect to the iPhone “iPhone” because an invalid response was received from the device." I tried to have a friend plug his iPhone 5S into it and it said the same thing. I read online that i'm going to have to do a restore on my phone, but I cant back it up to my computer to do so. I have also tried to fully uninstall iTunes and install an earlier version, but it keeps saying I must download the updated version, it wont even let me make a backup. There is no damage or anything done to any of my USB slots or my phone port, they seem to work for everything else just fine (Docking station, other USB compatable hardware, etc.)

I really can't lose all of my information. I've tried to use other apps (Dropbox, Google Drive, etc.) but I just dont quite trust them, and I don't know how to get all of my things back on to my phone. If there is a way I can fully backup my phone to my computer, restore it, and then throw everything back on it, that would be great. I would really like itunes just to work like intended though. If you have any information at all on how to maybe fix this or at least work around it, PLEASE let me know asap.

iPhone 6s Plus, iOS 9.3.5

iOS9 or newer on a mobile device requires iTunes 12.3 or higher which in turn requires a computer running OSX 10.8.5 or higher. Software Update only checks for updates for the current system version you are running but that itself may be out of date. It may or may not be possible to upgrade your computer to the required system. Find your computer model on the http://www.everymac.com web site and near the bottom of the system specification section it will say what OS versions it is capable of running. If you cannot run a newer system you will not be able to sync this phone to your present computer. If it can run 10.8.5 or higher you can either buy a download code for OSX 10.8 Mountain Lion from Apple online, or you can try installing the free El Capitan OSX 10.11. El Capitan may run slower on older machines and require additional RAM purchase (4 GB is a realistic minimum and many recommend 8GB). Doing a big jump in system versions is also more likely to affect old software.

Snow leopard to el capitan, will it cause my macbook to be slow? - https://discussions.apple.com/thread/7412959

Mountain Lion 10.8 purchase link U.S.A. - http://www.apple.com/shop/product/D6377Z/A/os-x-mountain-lion

Mountain Lion 10.8 purchase link U.K. - http://www.apple.com/uk/shop/product/D6377ZM/A/os-x-mountain-lion

Current OSX general upgrade information, including system requirements - http://www.apple.com/osx/how-to-upgrade/

If you have any PPC generation software that has been running under OSX 10.6 it will not be supported under any later system versions.

This is the new Apple. Update your mac os so it breaks all your apps and then buy a new mac then your phone will work with itunes. Its a sad day for a once great company who has totally lost their way. Goodbye Apple.
