black screen, stuck in dfu mode and error 4014, need help pls
Hello, i just bought a iphone 11 from a friend and the screen doesn't turn on, when i try to use itunes it says it's in dfu mode and when i try to repair the phone (with itunes) it says error 4014, i tried different cables, different computers (both pc and mac) and cleaned the lightning port but it did nothing. My friend said that the phone got dropped and never turned on since (the screen is looking perfect and it kinda turns on when i use itunes but it turn off again just after). And yes i tried some "repairs" like tapping around the screen and the back glass, force restart the phone (doesn't do anything to this phone), put it in the freezer for 30 minutes, let it charge for an hour and nothing helped. Pls help me, i don't wanna spend money on reiboot for example if i'm not sure it will work.
