So to make a long story short I was being careless and the antenna cable that is soldered next to the lightning port came off. I was curious how I can go about reattaching it. The solder spot seems to be covered in hot glue. I still have the cable too. Any help would be great! Thanks, Shane
Best to just replace the part it’s only a few dollars. Here’s the IFIXIT guide: iPhone 7 Wi-Fi Diversity Antenna Replacement and here’s the part: iPhone 7 Wi-Fi Diversity Antenna - Apple P/N 821-00513
