Earth 2 is more technologically advanced than Earth 1. If Earth 1 has a portal machine, do you think Earth 2 does not have a portable one? Also, keep in mine in season 2 of Flash, there were breaches all over Central City. Like I said, start thinking out-universe, not in-universe. You can't keep up with the writers if you think in-universe. They think out-universe then think in-universe to explain the "how" and "why".
