Chosen Solution
I removed the front panel and screen and reinstalled, afterwards I have no bluetooth and Wifi is greyed out. I am not unfamiliar with electronics repair, but have never had an iphone apart. Anyone have any suggestion where to begin to look for a problem? I didnt removed or detach anything from the back of the phone, just the display side. Thanks
Dead wifi/bluetooth chip. You probably shorted/knocked some components off when removing the display cable or you did not properly discharge yourself of electrical charge, causing ESD to the logic board.
