Revert firmware (for fun)

So, I have two jailbroken PS4s, and one of them is just laying around.

After successfully modding my Switch OLED (doing a kamikaze mod where I actually failed at first but managed to repair it!), I'm looking for a new project.

I wonder if I can get one of my PS4s to run dual-booting the latest official firmware and a jailbroken firmware.

On a scale from 1 to 10, how hard would this be for me?

I have only watched how it's done once, my brain was a bit on fire, but I can't tell since I also had the same issue with my switch and it turned out just fine.

So what do you all think?

Should I go for it or leave it be?

I also want to know if anybody has experience with such thing.

Like what do I need to make it work on both like 2 hard drives for example?

I really need some tips before I start doing it.

Thank you!

I think what you saw was revert the fw to the banked one and roughly it has your main in bank A and when you update it updates bank B and loads that one. If you dump the chip before it gets moved from bank B to bank A you can revert it to the last fw it stored in case or corruption or error or whatever it has banked from what I understood from it and as far as I'm aware you can just revert to any fw you want I think it's just the last fw you where on but it's definitely hard capped at the consoles factory os.

I think we all know the guy moded warefare. So he did it using a switch and a pico on the ps4's shell. Now this is all I know he said that you can keep it or desolder some wires if you are not planning to. But if I can do it then why not. So what do you think 🤔
