You need to purchase a E3 Flasher to downgrade your PS3 but only certain models are able to be downgraded.

If Your Are Above OFW 3.55 You Can't Downgrade Your Console. If You Want To You Either Need To Purchase An E3 Downgrade Service Around $50-$80 Or Get An E3 Flasher To Downgrade Your PS3 Your Self... & If That's Not Something You Wanna Do Then You'll Have To Buy A CFW PS3 On Ebay Like Id Say $250+
