My grandpa found an iPhone 8 he thought he lost, and found it dead. He can't remember his password and if I try to plug it into my computer it shows an error message saying I need the pass code to use an accessory to an outside source like a PC. It won't allow me to access the camera so any of those tricks won't work. I can't hard restart by holding the power button either, because when it turns back on its disabled for an hour. Help in any way would be awesome thanks!
