Why has the iPhone 6 stopped working after a successful water repair?
Recently I encountered a water damaged iPhone 6. It showed no signs of life (even though the battery still had a healthy charge discovering later when running tests)
I stripped the phone down, soaked the main board in 99% alcohol for 5-6 hours, dried the board and then brushed it clean from any water damage. After replacing the dock connector flex cable, the iPhone powered up and all functions worked as they should.
About a day later now, it is dead as before, showing no signs of life. The battery had been charged up to about 78% the evening before and the phone was working as it should. I have now replaced the battery and still nothing.
I did not remove the IC chip metal covers as they appear to be welded to the main board.
Is this a good question?
