Have I ruined my iPhone? Problems after WiFi Antenna Fix
Long story short: WiFi was greyed out and read on here that I needed to replace the antenna (iPhone 6s Wi-Fi 天线更换). Anyway I did it and all seemed to have gone well however:
Phone wouldnt power on so plugged in and switched on fine. No discovered not only does the wifi still not work, the power button volume and the mute button have all stopped working.
Any help would be much appreciated as I feel I've just wasted $300 and going to have trade it in for $20 :(
