Well you ether have to be on a Phat or slim ps3 not the super-slim if you dont know what they are then look it up and you best bet and buying a ps3 on 3.55 ofw from ebay because if you new to it then it will be better then trying to downgrade with a E# Flasher. Any way you just have to look it up on good and stuff and "redbug" if you mean "rebug" as of right now rebug website is down and that's the best place do to get their downloads and since their was a new update to 4.75 you will just have to look up a spoofer that was from a couple hours ago since it just came out June 1 2015 then you will be fine and you will need to get PsNinja it clears your history from sony servers so they don't see that you was on your homebrew apps. So since you are new to this go with CEX its easier for noobies and wont get banned s easy ether. Other then that its really easy just look up on youtube. need any help when you go to try pm me.
