Can anyone please teach me how to install and run petitboot from a flash drive? I'm currently on Rebug 4.85.1 LITE. Do I need to change my cfw? What do I need to prepare before proceeding? What steps should I take to get it running? Lastly, how can I remove it after installing it? Thank you. I really need a noob friendly guide here that has a step by step procedure. I only need petitboot and not install linux.
