回答“proximity sensor cable replaced, power button clicks now but...”I found out that I missed to replace both the UV-filter/foam + the shield thingy in plastic. Now my proximity sensor does not appear to work. I tried to put the shield thing back, but can't figure out how, as it is loose and falls off too easily. Don't know if I'll bother with opening it all upp for the third time. You can manage alright without it I think.
