I found a solution for the problem !!!!!
IN my case was not water damage .
My phone was totally dead i was not able to charge it at all , because of the water drop icon and alarm .
so when it shows the icon +alarm [ the phone must be on the charger }
Press and hold 20second power button and volume down
than press and hold volume up and down .
the phone is restarting . [will charge only when the phone is on ]
let the phone charge to 50% than FActory Restart
The phone works like a new !
