Playstation 3 jailbreak with HAN?

Di
- in PlayStation
3

I'm about to jailbreak my PS3. I saw a video in YouTube how to install on the Playstation HAN or HEN. I have to install before in GTA5 mods. I do not have a clue of it. What do I have to consider? Is it possible to undo the jailbreak? What are the disadvantages of a jailbreak?

If you do that, do not go back online with your console otherwise it will not work anymore
