found a unlocked game save that will lock as soon as you upload it to your ps3
this is on the 2nd mission and gives you all MG parts and some imported weapons, Max GP, OS and builder Exp. Complete the mission and you should be able to start building!! Not sure if all trophys pop or not.
Credit to the people at PS3セーブエディター掲示板 and [PS3]Gundam Breaker Savegame Cheating | Keha World Blog And deathscythe86 for uploading the save
