I think the owner dropped it in the puddle of mud.

Forget about the spirit and alcohol, when you suspect a water damage use "JELT".
(it removes oxidizers better then spirit but more expensive).
If you suspect the phone was in the water, put it in alcohol (If you don't have Jelt or other anti-oxidizer).
And then reheat the entire PCB with Steinel-like heat gun and lot's of flux.

350C if it's lead-free, or 290 if it's leaded tin.

****WARNING!!!! Do not heat with steinel glued BGA's!!!*****

For me this technique fixes 70-80% of water damaged phones.
