I have my old iPhone SE laying around in my house. I factory reset it and it has an iCloud lock with an old phone number that i cannot recall and an old email which i am logged out of. If i replace the logic board, will this remove the iCloud lock?

icloud is locked to the logic board and no other part of the phone so if you swap with a board that has no icloud then it will work, its not removing any lock its just swapping a board, remember that touch id is paired with the original board so if you want touch id you will need a matching home button for that board
