I'm posting this here, because i don't like the techno babble that can be found in the official forums.
I have a ps2 version 2001A with 4.46 Firmware. Even at age 23, I admit I can be just plain stupid, so assuming my PS3 is jail breakable, how? I don't care about technological aspects, I care about how its done.
I'm starting with the PSJailbreak Manager pkg, but i have (virtually) no clue on how to use it.
You need to get your firmware down to 3.55. You will need to get a hardware flasher to downgrade. If you would rather have someone do it for you check out the sticky in the marketplace. Racer offers a stellar service for members.
