open phone, heat your HOME OVEN to 160-170C
Place on baking tray, put in oven for about 4-5 MIN

What you are doing is, reflowing the solder and reheating the IC's, and also drying out the water.
Some say drying out water onto PCB will corrude the board, but also same time if you dont do it, it will corrude the board.

Also check the board for ayny physical damage, ie/ capacitors removed,

Do not use hair dryer to refow board, as the ****er and hear are not hot enough.

thanks
