Hacking rock band 3 update/ios's

[professa]

hi
can anyone tell me what ios's i need to run rockband 3 from the disc channel with a wiikey 1
getting 002 error
is there an update on the disc and if so does it update the sys menu - i'm on e4.1 at the moment which is where i want to stay if possible
also have the same problem with guitar hero w.o.r.
i do run most of my games from usb but have never bothered to go through the hassle of getting the instruments working with it
any advice would be great
thanks
