Chosen Solution

It may be too late but last afternoon the case cracked and some water got in, I noticed some salt forming from the water evaporating and also noticed it was getting pretty hot. I took out the battery and SD card but the SD card is broken. Now it will not turn on or charge. Again it might be too late but any ideas?

I’m not sure who to thank for the information on water damage for my GO PRO 3, cleaning all the internal parts with Isopropyl Alcohol worked, I was about to replace the mother board, and thank you for the tear down information of GoPro Hero 3 as well. THANK YOU ONCE AGAIN
