Hello everyone! My phone is totally dead atm.. I would love some help here. Today a bought an iphone 6 pretty cheap and i knew there was someting wrong with it but i thought i would have it a go for repairing it myself. #The Problem: it wont start up what so ever. No light, no sound - nothing. Have tried charged it for a while, i have tried to connect till both computer and wall. Have tried to replace the battery, chech the cables etc etc. #What i know: The owner before me had a screen and backcamera-replacement by a phone workshop. And after that it worked for 2 months and then suddenly never wanted to boot up anymore. #What it found out when i opened it up: 1. When i loosened the battery connectorcable there was some kind of transparent glue there. The same type of glue wich someone also had fastened their battery with to prevent it from sliding around. You are not supposed to use glue here right?? 2. What might be the big issue(?) - When i compared this iphone to my other working iphone visually, i saw someing wierd. There was a piece missing. It was the "the antenna interconnect cable". But i have no idea what this one does or if its really necessary to have??! I will link a perfect picture of it from this site:https://d3nevzfk7ii3be.cloudfront.net/ig... Do you guys think my phone might boopup when adding this cable??
