Hi there, sorry if I am posting this in the wrong place I am new here. I recently started to try and learn a bit about cell phone repair. I bought a bunch of old phones on ebay, none of these phones were meant to work but there was an iphone 6s which seemed to turn on but needed a new screen. Anyways I bought a replacement screen and replaced it and it turns on and looks good but there is a passcode on it. Can anyone recommend a way of getting past this passcode? I have searched and read countless articles that all say to restore it using itunes but that doesn't work. I have downloaded itunes but when I connect the phone nothing appears. Any tips would be greatly appreciated
