Super Street Fighter II Turbo HD Remix and other games or DLC seem to deactivate based on time (you have to reconnect to the internet for them to stay active). This fixed those and also reactivated my DLC for Blazblue Continuum Shift (I thought I had completely deleted the DLC files, I guess they just became deactivated after I patched the game to CSII and didn't connect online). That's some of my lost money recovered but a little too late considering the update/sequel was released on the 14th. The DLC mattered because it contained my main character... each DLC character is $8.
Hatsune Miku Dreamy Theatre (yeah, I like music games) still doesn't work though, it hasn't worked since firmware 3.41.
Edit: I should clarify for those wondering why I would delete the DLC to begin with. I deleted the game files to make sure everything goes smooth when I patch it, apparently some sort of corruption (I forget) was possible. I had forgotten that the DLC was contained within that and lost access to my DLC since I couldn't go online with that PS3 again. So now it seems the files deleted only contained whatever was needed to keep it active, not the DLC itself... which leads to even more questions.
I'm a little late to the party but I just wanted to say those directions worked, thank you. It was a little annoying and took me a while because I forgot I had to have my Rebug CFW in normal mode first (so the 3 files match).
