Question [HELP] Lg Optimus L9

Hello, I would like to root my LG Optimus L9 (I have rooted c.phn's before) but i'm scared that i might brick it because i think the tutorials are outdated or probably not for my version
  • Android Version: 4.0.4
  • Soft Version: P768g10b..

All i need are some links to still working tutorials on how to root it
Thank you
