Hi I replaced my screen and battery after water damage (moving over my old Touch ID/home button to new screen) - phone appeared dead. I then removed the home button ribbon cable connector from the board (top right of the phone where the front camera ribbon cable etc connects) and noticed the screen fire up. Phone appears to function fine (using home button accessibility on screen without ribbon cable connected) Could the home button be damaged and causing a short circuit? Or does it sound like I have perhaps incorrectly reinstalled the button in the new screen? Thanks in advance
Hello on iphone 6 the touch id flex is connected to mother board using a shielding plate. When you replace the screen did you change this plate or keep the original ? This should be replaced to avoid any doubt. In mainy case i ve seen water destroyed the touch id function but i can t remind a case where the boot was not possible. check your bottom connexion and check with a new shielding plate
