nokia 5130 is water damage .not working

If you phone fell into water then you can't do much, consider it already dead, however you can try following as I have seen few phones working cool after such incident.

If any phone happen to get wet or fell into water then first thing should be done is to take out its battery. Then dismental it as much as you can and then use hot blower like hair dryer to dry it.

Even after hair dryer use, don't use it, leave it open for 2-3 days and then use battery again and see if works. Most probably it will work but if doesn't then may be its time to buy a new phone !
