Worst thing you did was continue to use it that night. I dropped mine in the ocean and had to go down four feet to retrieve it. I immediately removed my battery. Then I gave it a bath in distilled water, changing out the water several times to ensure all the salt was out of there. I had it completely in distilled water for a couple of hours. Then I took it out and let it air dry for two weeks. After that I replaced the battery and it booted up and worked fine. I was advised to use distilled water by an electronics company who specializes in repairing police radios. They said the three most important things are 1) remove battery immediately 2) give it a distilled water bath even if you drop it in frssh water. Fresh water has minerals and chemicals that need to be removed also. 3) Do not attempt to restart until completely dry.
