I have a good condition iPhone 6 that has water damaged and will not power up no more. I have done everything I can to bring it back but I am afraid the logic board is garbage. I am going to try and replace the IC power supply chip to it and see if that will do the trick. If that doesn't work I will need to replace the whole logic board. Can this be done on the iPhone 6? I read that I need to remove 3 chips off the old board and put them on the new board. Can anyone confirm this please and if so what are the chips called that I need to remove?
