(adsbygoogle = window.adsbygoogle || []).push({}); Well before anything, I know this has been probably asked a lot but I want my own personal answers:

I wanted to know if there's a completely free way of Jailbreak a Slim PS3 with Serial: CECH-2001A
-By Completely free I mean no eFlasher, I do have flashdrives.
-Can I possible downgrade from 4.56 to 3.55 CFW?

I already checked and my PS3 came factory installed with version 2.70 but it recently isn't able to read discs anymore so I bought a new one and I don't want to throw this one out to waste when I know I can jailbreak it.

So yeah, sorry if this is unorganized, just want to jailbreak this.

no, you need a e3 flasher. I do downgrades if interested. Only $40

Yeah mastakiller is right you need an E3 flasher to downgrade
