iPhone 4 wont charge after battery/dock connector replacement
My helpful 2yr old twins washed my iphone for me 6 months ago. I think they were trying to make up for flushing one down the toilet earlier this year.
Depressed, i tossed it in the rice and bought another phone. Of course i was dumb enough to try and charge it and turn it on fully waterlogged.
Fast forward to now--i discover iFixit--time for resurrection!
I have replaced battery (3x) and dock connector. Phone works great --using it to make this post!
EXCEPT it will not charge. at all.
I have cleaned logic board with isopropanol (1x) and saw corrosion/black marks under heat shield at charging section.
What is my next step? (Besides turning off all water fixtures in my house until the twins are 14)
I just know you smart folks can help me
UPDATE April 8 2015
I FIXED IT!
This was a long time coming.
I had to learn microsoldering, start a new career, and practice it for a few years, but tonight, I replaced the PMIC, the Skyworks baseband chip, the charging coil and few corroded caps to solve this phone. It boots and charges. I wrote a blog post about this--
what a milestone!
Is this a good question?

Hi There:
I have the same problem. Change to a new dock connector but still won't charge. Does anyone know what other parts can be wrong?
If you know the answer, please post here.
Thanks....

Thanks for responding oldturkey03! The board looks pristine, except for telltale black marks on the heat shield directly above what you indicated in the diagram as the Charging Coil L2_PMU_AP.
I own a multimeter that I've used around the house before, but I'll have to have the internet teach me how to use it to check continuity at this coil...not sure how to do that.
The coil isn't loose, so if indeed the problem is this coil, is the solution motherboard surgery, or is this the end of the line?
I have a couple of other iBoards that I've collected in the last few weeks that need some connectors reattached. Surely microsoldering can't be *that* much different from when I used to do stained glass....
What are my next steps?
