Erase iPhone with black screen and signed out
So I broke my phone pretty good where only 1/3 of the screen recognizes touch screen. I signed out of the phone and borrowed another iPhone in hopes I could use it for the time being. I finally got my replacement and need to send the broken one back, but I cannot erase the content on the phone. When I power up the phone it looks like the "HELLO" screen, but I cannot proceed any further. I plugged the phone into my laptop and opened iTunes, but iTunes does not recognize the phone. I am not sure what to do now and looking for advise please.
