iPhone 4S isn't recognized

Hi! I have an iPhone 4S and from two weeks ago since yesterday it wouldn't get recognized by my MacBook Pro and neither by my PC... In these two weeks I replaced the charger port inside the phone and two cables... Yesterday I finally got it recognized on my MacBook while running TinyUmbrella, but, in iTunes said something like I need to connect the device so iTunes could see it (***?). Ok, on TinyUmbrella I pressed Enter Recovery (I was thinking to put the iPhone in recovery mode so I can restore it and posibly get it recognized by iTunes) - bad choice. Since then my phone is stuck on "Connect to iTunes".. I tried to hard reset it, it didn't work, I tried various programs ( iReb, RedSnow, TinyUmbrella, iFuntastic, DrFone, FixRecovery and so on), it didn't work, I tried to uninstall iTunes on both computers and put an older version, it didn't work, I tried on a friend's laptop with fresh installed iTunes (Android user) on it and guess what? It didn't f****** work.

P.S.: I run iOS 7.0.4

I really don't need people here posting that they have the same problem, I need a solution before I will smash my phone with a hammer.
