Tried this method to activate my RockBand DLC and didn`t work ....
I have YLOD on my old
ps3, but I was able to backup the home folder in dev_hdd0, witch contained exdata folders for all usernames on my consol.
Also was able to backup the game data for RockBand witch has about 200 downloaded songs in it.
What I did was replace the home folder in dev_hdd0 in my new console, copy the RockBand game data and rebuild database in order for usernames and game data to appear correctly.
Then I followed all the steps in grimms tutorial.
After pressing R1 as I started the pkg file, I didn`t get the BK0001 folder, just the pubPSN (if that is a problem).
Everything worked flawlessly. But when I enter the game ... the songs are there but when I want to play a song it says UNABLE to LOAD.....
Any help ?
