Hi! A friend of mine gave me an iPhone 5c and he wants to use it.I did the recovery and update with itunes part and it went ok but I got stucked on the apple id.It seems that the phone had a previous user but we can’t reach him anymore so we can’t learn his apple id and password. My question is this. If I try to change the logic board with one from the ifixit parts will the apple id stay the same or it will change so I can create a new one?

If its a new logic board then there will be no icloud linked to it

I’m guessing it’ll be a different number.
