Yeah you need exploited PS4, but fw 9.00 is exploited now (and it's pretty stable apparently) so it should be easy enough to get a used console and exploit it.
Mine is still on fw 5.05 so I still have to wait for backports. I have never had any kernel panics and never had to restore my HDD so it's the only reason I'm staying with what I know works best
Plus side of fw 9.00 exploit is everything runs without backports atm. As I said it is meant to be
heaps more stable than 6.xx or 7.xx exploit though, no idea if it's truly as good as 5.05 exploit
