Can someone tell me which Lumines is the one you need to downgrade? Which official firmware do you need Lumines to do this with? I downgraded mine with GTA:LCS Unpatched which I had to get on ebay for like $60. when did Lumines come into the picture, and does it have to be a certain version? I have Lumines, but I'm not sure if it is the right one if I need to help out a friend.
