Go back to Goldenrod city. You will find a whole bunch of team rocket members there. Enter the radio tower and you'll find a rocket member guarding the stairs, and won't let you through until you get a team rocket suit. Leave the radio tower then go to the underground passage in Goldenrod, in there you should find a Team Rocket member next to a camera.
Talk to him, and he'll give you a suit thinking you're a new recruit. Now go back to the guy at the stairs and he'll let you through. Now just beat the team rocket leaders/members and then you'll have access to Blackthorn City.
Then you go to Mahogany Town and the rage candy bar guy will let you go through.
