I hope this solution can help others, but this is all on you own risk!

I had a logic board wich didn't charge and wasn't recognized by iTunes. When i disassembled the iPhone, I saw there was a part (see picture) on the logic board that looked a bit fried.
When i touched it with a screwdriver, it fell apart. I've been looking on google to find out what kind of part this was, but couldn't find it. Only thing i found was that it's soldered on the logic board with 6 connections.
I decided to take a guess and scraped it clean with a little screwdriver, and put some soldering tin on it.
Seems it was the best guess of the day, because when i reassembled the iPhone it was chargin again and recognized by iTunes!!!!

I will try to post a picture later of what i looks like now, but my camera doesn't like the close up shots

Again, if you are going to try this be carefull because it also could go wrong!!!

hey mate... have you made some more pictures yet??

No, and i also reassembled the phone so it's going to be difficult to take pictures now
Also there was not much to see on the board, only the chip that was removed, and a lot of soldering
I noticed that the phone won't charge on the original adapter, only with an imitation that is 2A instead of the original 1A, also usb won't charge either...
