Hey ChromiumBlaze,

Sorry to hear that you are having issues with connecting your iPhone to iTunes. I know you have tried an extensive set of troubleshooting but lets check out another option. 

Below are two articles for what to do the your iPhone is not seen by iTunes. You will only need to pick one of them depending on the type of computer you have. They might have some information that bleeds over from the other troubleshooting you have done previously, but give that a shot to see if you can get it sorted out.
