Hi Just encountered a problem. I disassambeled my iphone to change the housing, then when i put in back together it worked fine, but it stoped charging, which I noticed this morning when I found my phone pluged to the wall with an empty battery and a thunderbolt on its screen… So the question is might it be the broken wire of the dock connector? Im not sure because itunes still finds the phone in dfu mode and I even tried to restore it but it didnt work…
If the dock connection cable is loose or damaged your home button won’t work either. If this is the case then all you will need to do is replace the dock connector and you should be good to go. You can also check to see if the connection has been made properly. If your home button is still working (press it and see if the screen turns on) then continue reading. When you replaced the back assembly there is a possibility that the battery feet were not correctly seated and therefore are not receiving any charge. Try taking out the logic board and making sure the battery feet are correctly in place and have the screw holder in the middle. Below are two images of the correct and incorrect placement of the battery feet. Wrong
Right
Hope this helps! :)
