I have an iPhone 3 that I am fixing for a friend, she dropped it into the laundry about a week or so ago. I purchased a new battery and all the products needed to clean the logic board and connectors. After extensive cleaning, and drying I swapped out the new battery and put everything back together. I let the phone charge for an hour or so before I tried turning it on. When I did I immediately saw the apple on the middle of the screen. But it never powered up. I haven't tried a force restore yet, but I don't think that it needs one. Im thinking it is possibly left over corrosion on one of the connectors. Does anyone else have any ideas or thoughts? Thank you.
