If all else fails you can just purchase a new dock connector, I just replaced mine a few min ago and it charges like a champ now (oh btw I had similar problem)
"connector for digitizer cable damaged 7 require to replace"に関する回答If you want to change the ribbon try here: iPhone 3GS Front Panel Assembly But the locking mechanism (FPC tab) on the board I don't believe you can change out just go fresh and keep steady, number 3 was a pain for me too
"The #1 ribbon for the LCD keeps de-attaching"に関する回答1.) Check to see if anything is bent or in the way (usually this is the problem) 2.) Make sure you hear (or feel) a nice click when you connect the ribbon to the board 3. Repeat step 2 if your still having the problem (if nothing is damaged) and keep patient, take a deep breath, those suckers are tricky. 4.) If your still having problems you might have to change out your display if the ribbon is damaged. 5.) Or if everything is fitting properly and you just want to secure it use some circuit board tape or something that will hold tight but not leave residue. Display: iPhone 3G Display GOOD LUCK!
