Remove logic board shield cover. If your phone is not damaged much with water, you may not need to remove the shield cover since it may risk harm to the small elements placed on the logic board. Still, if you remove it, go ahead with caution and use plastic tool like spudger. You may also use a plastic opening tool in order to life off the shield. Observe the dimpled tabs on shield which reach down on the tabs that are connected to mother board.
