How to troubleshoot water damage
My iPhone 5s was submerged in water and stopped working. I followed the water damage guides and disassembled the device and cleaned the logic board with alcohol and dried thoroughly. After re-assembly, the device worked perfectly for about a day and then died completely. I then repeated the procedure and also replaced the battery. Unfortunately, I still have a completely dead device that is not even recognized by my computer. How can I troubleshoot the problem?
Is this a good question?
