Battery not charging after DIY repair.
My wifi signals were very weak so I decided to replace wifi flex cable. Using ifixit app I read the tutorial and fixed it. I was quite happy but later on realised phone is not charging. I opened my iphone again and checked if all cables are attached and they were perfectly placed. I switched off my phone and connected charger it powered ON but again it wasn't charging. Please help me. And also tell me which cable transfer current to battery. Maybe,I would have dislocated something.
