Chosen Solution

So, I dropped my phone in water and I took the logic board out to clean off the corrosion. Before cleaning - The phone is in infinite reboot, it gets to the white Apple Logo for about 10 seconds or so and then turns off and repeat. After cleaning logic board - the phone does the same thing but now the screen is super dim. Like so dim that at first I thought I completely fried the phone. Basically I think the blacklight broke. What should I do? I am planning to get a new battery for this phone and a new screen. Is there any suggestions on what happened or what I should do? Note: I am not trying to repair this phone for extended use. I might use the phone for two more months until the new iPhone comes out. I want the phone to turn on so I can back it up and get my data off of it mainly…

Water damage repair is a hard fix, most techs will only repair phone and hope it stays on long enough to get data off. If phone happens to continue working after if has been ultrasonic cleaned and components replaced that were damaged then the device is good to go. If the contaminants in the water are not addressed properly they will creep up and damage other components, constant heat from the phone being turned on and whatever was left behind will continue to grow and damage phone. make sure to remove shield to clean all components on motherboard. look for smoked or charred components to give you clues as to where the damage area might be.
