I replaced the WiFi antenna but it doesnt work. Do I need to insert all screws/brackets in order to get the WiFi antenna working properly? It did Work unil I inserted all screws back in and then the WiFi was greyed out again.. I tried it with multiple WiFi antenna’s and tried to restore the device but nothing works. Well; sometimes it does but it greys out again.. Suggestions?

Greyed out wifi switch indicates wifi chip problem, not antenna.
