    I found out the issue to my previous thread I am trying to boot into a previous firmware so how do I update to the latest firmware? I have access to any payload but not sure what to use or how to use them

    Do you have AutoRCM installed?
    Did you restore boot0 and boot1 as well?

    You could restore a backup (if you made one) from before you tried to downgrade? If not, you could probably use the PC version of choidujournx.

    I honestly havent kept up with this part of the scene enough to know if there are now different formats used for the key file. I see different file extentions floating around for this (ini, txt ,.keys). Maybe you are better off downloading a prod.keys template somewhere and fix it yourself.
    Good luck

    Damn well thanks anyway :D Been trying to fix this, I just wish it was possible to just get into the original firmware into recovery and I'll just go to 6.2.0, I think trying to use a RawNAND.bin for 5.1.0 broke everything but allowing me to run payloads.

    For what it's worth, you can generate new ones. If the boots are the only thing missing from a backup, it's entirely salvageable.

    How would I go about that? Currently trying to do the "How to install/run" guide but now stuck on obtaining prod.keys lol If it isn't one thing it is another it seems

    I ran through the choi guide and used the firmware files of my nand backup firmware (2.3.0 update files to match the 2.3.0 backup). You only need to follow it up until restoring the boot0/boot1 parts, and your previously-failing backup should now boot.

    ok I'll give that a try. I am still not sure how to obtain my keys.txt file though which is the current issue. I can't boot any CFW so not sure how to obtain it. I tried downloading but it just fails to match anything.

    Yeah the same issue it requires prod.keys and I'm not sure how to obtain those.

    You don't have to do any of that. Use hekate to boot your 5.1, and update with ChoiDujourNX

    How would I do that? In the options I can hit boot normal and it just black screens. I can't get beyond a black screen or a blue screen with anything I do
