So, in 2017, I brought my iPad mini 1 in for a digitizer/glass replacement after I cracked it and after they fixed it, I got it back erased. I sadly didn’t ask the guy why.
Was it replaced by a 3rd party repair shop or apple itself? I do not see why it would have been erased unless there was damage to the logic board as well. (And they had replaced the logic board)
