I have a iPhone 11 Pro Max that was dropped and drove over by a golf cart. Had the screen replaced already and thought was good. Back is also still cracked. Cellular part still works but can not use the internet or WiFi. Any idea what I need to buy. Has no protection for repairs. So I thought I would myself. Please help.
You could start by changing the wifi antenna but my guess is the connection in between the split board is broken. I would take it to a repair shop that does microsoldering work and have it checked out. Also if the back is cracked and it gets wet water will poar in.
