No to put a CFW on your ps3 you can only do it from 3.55 or below. You are required to flash your ps3 using a e3 flasher, e3 flasher's cost around $100 but i just recommend buying a jailbroken ps3 for around $200.

Or have someone downgrade it for you. But depends on the model and serial # of the model.

Firstly, you need to downgrade to 3.55OFW using a E3 Flasher which is around $80 on Amazon or eBay. Make sure that your console is able to be downgraded before you buy the E3 Flasher. Once you follow the tutorials on YouTube, you should be at 3.55OFW. From there you can install any CFW of your liking. I recommend 4.50ITA.

You can't install jb until you downgrade to 3.55 ofw then install jb
