    Can i extract the keys.txt/prod.keys fom a NAND dump? I unable to dump the keys with LockpickRCM and so i can't use the manual ChoiDujour Downgrade. I have a clean dump in 14 parts. I have biskeys backup too in the "automatic_backup" folder. Or is there a other method i can try it to get keys.txt/prod.keys? Can i unbrick my console anymore in this situation now? Or it was too late?

    Op why do you need to downgrade?. LockpickRCM is the easy way of getting all the keys. You did meantion that lockpickRCM is not working, mind to tell us why it not working for you?. :)

    My console bricked after my NAND restore and i haven't dump the keys before the brick. If i use LockpickRCM i don't getting the full keys because some says "corrupted". If i use there on ChoiDujour(no NX) it says "FAIL! Invalid NCA Header. Are keys correct?" = corrupted prod.keys from LockpickRCM. And my Backup wasn't working. So i have only the PC Downgrade method but without the keys i can't rebulit my NAND :(

    you only need specific keys, when u have keys inside the keys.txt file which ChiDujour dont want he will say that

    you only need these keys, ofc replace the X with the real numbers/letters

    master_key_00 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
    master_key_01 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
    master_key_02 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
    master_key_03 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
    master_key_04 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
    master_key_05 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXX

    header_key = XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
    aes_kek_generation_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
    aes_key_generation_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
    key_area_key_application_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
    key_area_key_ocean_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
    key_area_key_system_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
    package2_key_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXXX

    If I remember right, this fails if your key file has keys that are unneeded. I think the error should tell you which keys it doesn't recognise. (remove that line from key.txt)
