beat the fronteir brain
when you get to the battle fronteir you have to beat each facility a set number of times (3-7or10) and at the end you will find the fronteir brain. Upon defeat they will give you the symbol)-warning they're tough. for more info go to: http://bulbapedia.bulbagarden.net/wiki/Battle_Frontier_(Generation_III)
Consecutively beat each facility to do so.

you half to do it 5 times in a row
after you beat a certain amount of challenges you will battle a frontier brain which is sort of like the gym leader. if you beat them you get a symbol
Well you could go to this website they have everything you need to know about Pokemon. (In my opinion) www.serebii.net First you need to be able to access the battle towers. You have to battle in one of the towers until they notice you are good at the game. A frontier brain will then battle you. Another website is, Bulbapedia.bulbagarden.net/ I personally like it better then Serebii
Once you have beaten the champion go to snowpint city and there will be a boat on the oracean.Talk to the man in front of the boat and hel take you to the fight aera.Once you get there ceap going right until you see a holse chube then go up and go through and you will find Barry and his Dad palmer the fronteir brain and ceap going up and you go in the building and youl be there.
Depending on who it is, you still have to beat the Brain.
Use ur brain
For each facility you need to beat the 7 trainers (there may be less in the battle pike and there are more in the battle pyramid) 3 times in a row then defeat the frontier brain on your 4th round. Note for the battle pike and pyramid you need to clear the rooms and floors a certain amount of times to battle the frontier brain.
