Option one is to get the hack walk through walls or go totheir HQ and defeat Cyrus first go through their HQ and defeat everyone.Hope I Helped ;)
You have to go east of eterna city.
Near the Galactic Eterna Building,there would be tree blocking the way,use cut
at the end of the cave
you have 2 beat every single galactic grunt, included those in the galactic building in veilstone city(very important)
