Didn't I already answer you in the previous post. You can do it, but you are supposed to go back down to 3.55 OFW then install Rebug or Habib, as for how, try googling, there are tons of sites with instructions.
Installing Rebug directly on Rogero will work, but can lead to small bugs and glitches, which is why scene vets always downgrade back to 3.55 first.
If you aren't too savy, I suggest you google yourself a Rogero 4.55 and install that instead, since it's more stable build. I've personally used them all, Rebug, Habib, etc. My preference is still Rogero 4.55. Its not about chasing the higher number, its all about stability.
