Before you replace anything else. Use a multimeter and see if you have power at the battery when you plug your cable into the dock connector. Always double check your work and make sure you do not have any crossed contacts etc.


If the IPhone is not charging or connecting to itunes, even after replasing the dock connector, it might be an shortcut. i had one on mine, because i cleaned my device while it was still turned on. in that case, the problem is not the dock connector, but the logic board. i`m not quite shure how you can repair this problem yourself, i just submitted then and gave my iphone to a repair shop. 52 euros and everythings working fine again.

Please note that if replacing the battery does not help, it may be the logic board.
