    Use ChoiDuJour (not ChoiDuJourNX)
    Or better : restore your nand backup

    It should work.

    (You'll have to boot through RCM)

    Of course he doesnt. He probably (like the rest of people who will come crying here) updated and now trying to find a ''secret hack'' to downgrade because he foolishly updated despite people literally screaming out every single update NOT TO FREAKING UPDATE before you know whats going on.

    You can't downgrade if you don't have a NAND Backup.
    You're out of luck.
    Even with a NAND Backup, you won't be able to boot into it cuz a fuse were burned during the update

    ftfy.

    For what it's worth, after a downgrade with burnt fuses, you can still boot into your system, you just need to use a CFW bootloader (like hekate) that ignores the fuse count.

    Don't worry about it too much. The new encryption keys will get released, SciresM is already working on it. There's just no time frame and it might not be soon.

    I downgraded from 6 to 5.1 without any nand backup, using only choix du jour and the update 5.1 files.

    Why would the nand backup up needed this time ?

    Because you cannot boot into CFW at all when running 6.2.0
