so recently my rock band 3 started working. I use configurable usb loader. so I want to download some dlc I bought a while ago, but it can never read my sd card. is it because I launch it off a usb? I can use it fine on my Beatles rock band when I launch with my disk. EDIT: So, after some research, I need IOS 60 to support my SD Card. Is there a way i can merge my ios 37 with 60? Thanks!
