Hacking Problem with Green Day Rock Band (Error Opening Partition)

[boblybob]

Basically the title says it all. Changed a few things is the song.dtb exactly as some guides tell me, so I don't think that's the problem, I load with Rock Band Launcher, shows some normal code text like Game Title: Green Day Rock Band, publishers, region info, then it stops at (-) error opening partition.

Do I need to update the cIOS or something?

Anyone?

If you change files on the disc you will need to run it under an IOS that accepts fakesigning.
This game in particular also checks to see if its files have been modified, so it will still crash soon after launching.
