How to go to a different CFW?
I am truly sorry for asking such a basic question, but I did do searches and readings for hours and don't quite get the whole thing.
My brother installed Rogero 4.21 on my PS3 and in his absence, I don't know how this thing works.
I am interested in Rebug 4.21 and Rogero 4.30.
How would I do either?
It looks like Rogero 4.30 v. 2.03 came out recently, which says no need to downgrade.
Does this mean that I can just put the PUP file on a USB drive and go to system update on PS3 XMB and do an update and that's all there is?
What about if I wanted to change to Rebug 4.21 from either Rogero 4.21 or Rogero 4.30 (after the said update above)?
If you could explain the steps (as well as why we do the step) or a guide somewhere, I would be really grateful.
Once again, I sincerely apologize for posting what I am sure if yet another stupid question (I tried what I could but couldn't wrap my head around it), and if I am not looked on with pity, I accept it too.
