It doesn't sound like you have much experience in manufacturing. No, you don't pull a run of hardware mid-run to rev their firmware unless there is an absolute shitstorm which would also just be handled by the manufacturing process i.e. why would you ship the "bad" cards to your office or some such scenario rather than run them again through the same at-scale manufacturing process? Anyways, as somebody already pointed out, the vast majority of these cases would be handled by live updates.
