30 - 45 minutos
The phone had taken a bath, actually going through a wash and rinse cycle in our clothes washer. After having it dried out I was told that the motherboard was bad and that I'd have to get a new phone. I found a MB on IFixIt and got it in a few days.
I had the phone apart and ready to go when the MB came in. It took about 10 minutes to assemble. I have really big fingers and the connectors are very small so patience was in order. Turned on the phone and it worked. What else can I say but "Thanks!"
Fix it, don't toss it!
