Liquid damage is one of the most difficult repairs. As soon as a phone is exposed to moisture, rust & corrosion begins to grow, so the sooner you get it to us the better. If it is just rust or corrosion, chances are pretty good we can bring your phone back to working condition. Sometimes the power from the battery causes a short circuit on the main circuit board. If this is the case, we cannot repair the phone. Chances are 50/50 or better on all liquid damage repairs.
