"iPod Touch 2G won't charge after battery was replaced?"에 답변I too had this same issue. I found that even with my soldering iron set high(over 700 degree's F) I could not really melt the solder from the factory. At best it became a little pliable. I got one exterior connection free, but like the others mentioned, the middle pad pull completely off even taking a little of the board underneath with it. I tried jumper a small wire from the ribbon cable to the small round pad in front of the damaged area but was not able to make a good connection so it will not charge. I liked the conductive silver paint idea. The local Radio Shack had a Circuit Writer pen. I used it to fill in the damaged area up to the round pad in front of it. Once dry I soldered the the outside pads and then barely heated the center pad to get a little liquid solder touching the silver ink. I have solid connections on all 3 pads now and the unit charges.
