I am using this update file:
Samsung Update: Multi Consoles

thank you very much.

In my experience, when I don't do the update. My E3 throws a random error when I try to dump. (usually because of the update)
So in my opinion, I would just do it because it doesn't take any time at all.

No, u only need to update your flasher once.
