    My PS4 is on fw 5.50. Is it possible to JB my console or will I have to update to fw 6.72 or can I downgrade to fw 5.05?

    You can't downgrade to fw 5.05. You will have to update to 6.72 but you can play all backup games up to 6.72. :)

    That should be it yeh, I think it needs to go into PS4/UPDATE tho.

    You can downgrade but it requires a backup of your SYSCON and it involved changing the chips.
    For now, it's not usable for the enduser.

    We need keys for “CFW”.

    We need backed up files (per console) from low firmwares to allow hardware downgrade from higher firmwares.
