Have an old PS4 sitting at 3.0 firmware, should I update to 4.55 or 5.05?

    I bought a PS4 3 years or so ago with the intent of keeping it in my closet waiting for the day it can be hacked. Now that it's possible, I plugged it in and its 3.0 Firmware.

    Should I update to 4.55 or 5.05 firmware to hack it? Or is there any reason to keep it at 3.0? Are there any downsides from either one?

    Are there limitations to any of these firmwares?

    Thanks guys, sorry for the newb questions, this is all new to me.

    If you want to tinker with it (researching PS4 internal) I think you can have some advantages with FW 4.05/4.55 as sometimes after FW 4.55 introduced some kind of SMEP/SMAP, also some people have the opinion that 4.55 was the most stable exploit evar. ^__^

    And trivially, recent titles can't run on older FWs unmodified (theoretically as I haven't seen such modifications myself), but you can runs some 4.55 titles on 4.05 though.

    You should. I had a 2.57 FW and I didnt regret update to 5.05. Are there limitations to any of these firmwares ? Well, the games up to 5.05 are fully playable. Any games that are above 5.50 are not playable. Right now, they have 5.50-5.55 fully exploitable in private. We dont know when they are release it yet.

    IIRC after 4.50 dumping PSID is not possible with flat z’s normal method.

    Game dumps can be downgraded using SDK of version you want to downgrade to as long as there are sufficient modules comparably. So 5.05 game can be downgraded to 4.55, if it doesn’t use anything too new from newer SDK than 4.55 compatible.

    Not many games can handle this.

    Imho 5.05 is the one to go for if you just want the biggest variety of games to play.

    Thanks for the response. I read that PS4HEN is very buggy at 5.05, is that true?

    And once I jailbreak at 5.05, will I be able to downgrade to 4.55 if I wanted to? I think that was how the PS3 worked... once you have a CFW you are able to jump firmwares...

    In my experience: 5.05 is fantastic, never had an issue, especially if you use 5.05 X-Project Host v1.5 ;)

    You cannot downgrade, yet.

    I thought 5.05 still has issue with USB devices. that's why I stick with 4.55
