Water Damage

[n_320]

The best way is to disassemble it, until you get the naked board (without display, microphone, loudspeaker, kamera module...) and to put the Board for about 24 hours in isopropyl alcohol (you get it in a pharmacy). Then it should get completely dry (about 1 day at a warm place), and if you have luck, it would work good. The problem is: the conductors will go on corroding and will be in some time broken. You can slow down this process, but you can not stop it.
