Pretty sure my GoPro Hero 3+ Black is destroyed. I dunked it for a second or two in saltwater in the late morning, thinking I had the correct submersible back cover on my on housing but didn't. Stupidly, I didn't think to remove the battery immediately and rinse with freshwater or anything. I let it sit to "dry" for the rest of the day and several hours later tried putting a different battery in to see what would happen. The red light came on as soon as I put the battery in so I took it out and let it sit. Later that night, I rinsed it in freshwater, took it apart via partial teardown and used alcohol and vinegar to clean out the corrosion that had built up. It didn't look too bad and I think I got all the corrosion out, but I'm pretty sure it was too far gone at that point. I threw everything in a bag of rice and let it dry a couple days - no go. Then I took it all apart *again* with a complete teardown and used alcohol to scrub/brush more thoroughly - I think I got most everything out the first time around but just wanted to give it a shot. I put everything back together just now and it's completely dead. Can't believe I was so boneheaded....arghh... definitely an expensive mistake :(
