How to find a PS3’s Model Number
To locate the model of your PlayStation 3, look on the back of the system and locate the bar code sticker. Underneath the bar code you will see the 11-digit serial number followed by a model number which begins with “CECH”. You can also find the model number by looking on the box. It can be found by looking on the top of the box (the side where the handle is located) and is printed below the contents of whats inside the box.

These easy, trimmed down charts will help you find out if your PS3 is downgradable and what the lowest firmware that it can be downgraded to. To see the full chart head over to the PS3dev wiki. Remember that 3.55 is the firmware required to install CFW, for now. You can check out the last column to see the min firmware that’s allowed on that console.



Hi need to know one thing can you downgrade any PS3 to CFW as long as it is higher than the lowest required Praxis?
So if the console is updated past 3.55 it can be downgraded as long as it was shipped at a firmware lower than that?
Yes assuming you dont have an Eflasher or Offical Firmware updated past 3.55

read carefully…i talked a guy from delhi regarding ps3 jailbreak. i had a ps3 3008b and he was saying that 3k model cab be jailbreak also. He assured me about that. even he was sure to jailbreak the 4k models. He told me that the cfw for 3k series is available in the market from two years back.
He’s a liar, it’s a scam.
