Hi! Replaced my Iphone back housing and now my Iphone dont charge. After assembling i noticed that my Iphone Ohly charged when the inserting one side of the lightning cable. If I turned the lightning head it wouldn't charge. My iPad charges just fine with both ends and so did my Iphone before housing replacement. I opened the phone again and checked the lightning thing and now it won't charge or be recognized my my computer but I can start the phone. My question is that there is four rings under the lightning contact and I lost one of them are they important for the port to work? Did I damage anything or get a new port to replace? Please help feeling like a failure, I was extra careful when replacing the housing and everything went great please help.
