My iphone is totally locked?

So i got my friends iphone 4s which has the ios7 that he got locked out of and i have tried so many ways of hacking it and now it says that it is disabled and to connect to itunes. I connected it to my itunes and nothing happened.

You'll need to connect it to the iTunes that it was synced to. Since it's your friend's iPhone it should be his iTunes you're connecting the iPhone to.

Can't you ask your friend for the pass code?
i had that same issue (my ex friend locked me out of mine then forgot the pass code ) and i plugged it in and had to restore the entire thing
when i plugged it in i went to my ipod and hit restore

Put the phone on DFU mode first (first switch off the phone, hold down the power button for 3 sec and just when the apple logo appears hold the home button without leaving the power button after ten secs leave the power button while continue pressing the home button for another 20secs ) so now your I phone is on DFU mode or recovery mode, connect to iTunes and format the phone.

Sadly if your friend had I cloud activated your screwed. With ios 7 there's no way to unlock it unless they are willing to give you their apple id and password. If they didt have it activated or they give you the info you need hook your charger to your computer but not the phone. Open itunes. Hold down the home button and plug yhe wire into the phone. Don't let go of the home button. After a couple of seconds the apple logo will apear on the phone screen. Look at your computer. You should see a pop up saying itunes has detected a phone in recovery mode. Let go of the button. Follow the onscreen instructions and your golden.
