My iPhone says “iPhone is disabled connect to iTunes”. I have tried everything to get it off this screen, but nothing will work. Even DFU mode won’t work because iTunes says the iPhone was previously in DFU mode, but it restarted and is now no longer in DFU mode.

Sadly the world has moved on! The cellular network this phone used is no longer active. The only way to connect is via a Mac or PC which still offers the older versions of iTunes via the special USB to iPhone cable.
