Wait....what? The sentence doesn't make sense to me?
Are you trying to say, you're on the hunt to buy a PS3 Jailbreak?... if so you can buy them on eBay and Gumtree. PM me if you need any help..

If you are trying to jailbreak your console via USB then give up and stop trying unless you system has already been downgraded by a E3 Flasher.

To check and see if your PS3 is downgrade able then turn your system around to all the component plugs and look next to the serial number and you will see something such as ( CECH 2xxx ( A or B ). You can also go on YouTube and search up ( Playsation 3 minimum version checker )

How to use the MVC ( Minimum version checker ) download the file and you will get a " PS3UPDAT.PUP " now plug your USB flash drive into your computer and make sure that you crate a file names " PS3 " and inside that file make another named " UPDATE " and open that folder and drag the MVC into the update folder. Unplug your usb and plug it into your Playsation right USB port and go over to system update and via USB you will see the MVC file up there click it and if it says your system can have anything under 3.55 you can more then likely be down graded depending if your motherboard has a nor chip.
