I recently replaced my iPhone 4S front screen,
Whatever I do now, it keeps saying "searching".
Removing sim card doesn't make any difference,
iPhone doesnt ask for code when I replace sim card.
I'm sorry, I did not know you were standing there and watched him reasemble it,
(it is actually very easy to NOT plug in the ant properly).
So sorry to have "butted in" 😱 (I won't in the future)
