Replacing the logic board is tantamount to getting a new phone. Its all on that board. If you do replace that board and you have to pay for it, be sure to retain the old board. Because if you still have issues your board is likely good, and they are worth almost as much on ebay as a whole phone. If you take the board out yourself,also remove the shields that clipon and the rubber under them and clean the components under here also. When water gets on these its not the water that does the damage, its the foreign contaminents that remain after the drying method has been employed. Remember RICE DOES NOT REMOVE TOILET PAPER!! After you clean this out (Gently with a toothbrush and alcohol and gently blow out with compressed air) repace the covers and rubber. I have found that most all motherboards come back to life after a proper cleaning, but since most of the components are nearly microscopic they are indeed highly seceptable to corrosive damage, because there isnt much tothem they simply disolve leaving behind a greenish scale like you see on battery cables, and when you clean it away the diode, or whatever the case may be, that used to be there, is simply gone.

Clean the board before you replace anything else on the phone.
