Wont turn on after lcd replacement
I have changed the lcd and now it won't turn on. the issue is now that it won't turn on again. when connected to iTunes it is recognized as "the phone you are trying to activate needs a sim card to activate. or this item does not exist. When connected to charging cable it vibrates to times with 5 sec. interval.
the repair is not new to me, i have done this repair many times.
i have tried to mount an other lcd with the same result. I can read, that some threats describe the it could be issues with CPU. Does any of you have experience with this issue?
