So my S4 i337 got completely submerged but I immediately powered down and soaked the MB in high percent isopropyl alcohol then put it in rice for days. Everything on the phone works wifi camera screen etc with an exception. No sound works and if I get or make a call it locks the phone up. Looking around the web I saw a lot of people had this problem from OS issues and fixed it by flashing the phone. I used to have this phone rooted but it isn't any long though it does still show as custom. I have tried flashing via Odin by I am getting immediate failures. I have tried several Odin versions pit files and i337 firmware files. My current version is 4.4.2. Any ideas?
