After a ton of work today, and changing around cIOS's and banging my head up against the wall. I got Rock Band 3 to load with USB support using IOS 249 Rev 17 coupled with IOS 222 Rev 4 and uLoader. However, tt seems that Rock Band 3s Keyboard will not sync with the dongle that came with it. I have heard of this happening with non-retail discs, but so far am unsure of any way around it. I was going to load it with softchip using a different IOS but softchip will neither let me change the booting IOS nor read the disc. Any ideas?
