    USER is another partition in HacDiskMount, he's not talking about another folder in SYSTEM partition.

    I also tried these and dozens of more steps (see other thread on gbatemp: "how to install run any switch firmware unofficially without burning any fuses"), but still no success for my switch. I am always being stuck with flashing atmosphere logo and then blackscreen with backlight turned on after sending fusee-primary.bin payload - so no chance to boot into HOS nor recoverymode or whatsoever.
    I realized, that deactivating autoRCM via hekate changed the behavior of flashing atmosphere to remaining atmosphere logo, but then still blackscreen+backlight - will give it some more tries.

    Alerappo, did you also (accidentially) downgrade to 1.0.0-7pre-release firmware via ChoiDuJourNX? If so, what was your last sysNAND firmware before?

    "6. Then we go to the USER folder and delete everything in the folders."
    Did you empty the entire USER partition, or just the content of the folders? What about the subfolders in "Contents" folder, did you already erase them or just their content?

    And what about PRF2SAFE.RCV files in SYSTEM and USER partition - did you keep or erase them?

    And after injecting fusee-primary.bin payload your switch directly booted back to HOS entering recovery mode for the user settings and ran through without giving any errors?

    If that was all true, I can just say: my honest congratulations!
    Thank you for your support!

    you might have to show hidden files to see PRF2SAFE.RCV files on the partitions. see the other thread I referred to in my previous post or look at the image attached.

    Can't help you with the rest, so I prefer not giving confusing hints here, sry

    I was stuck after the accidental downgrade from firmware 9.2 to firmware 1.0.0 (not pre release), immediately after the brick I dumped the nand and the described procedure works only if the switch is in the exact state it was in after the downgrade, when I tried to do the upgrade with choidoujur from pc nothing worked (i tried all firmware version always stuck in logo) and I couldn't boot, for this reason I specified that it is important that if you made a backup of the nand to firmware 1.0.0 do the restore before deleting the folder files and try to boot.

    Important to make sure to use atmosphere's 0.10.4 version and run it via fuse-primary.bin, don't use hekate for me it didn't work.

    Do you have nand backup to firmware 1.0? if so, do a restore of the nand.
    After restoring the backup, access the nand and on the system partition, inside the save folder you must delete the files except the one that ends with 120, inside the user folder you can delete everything.

    is there a reason why you point at atmosphere version 0.10.4 specifically?

    And what about the PRF2SAFE.RCV files?

    I am still stuck, maybe the pre-release is still different, I don't know.
    At least I got the backup to always return to the last state and try again.

    Yes for compatibility with firmware 1.0, but I don't know if with pre-relase it works, on 1.0 the version 0.13.0 did not start the cfw but only the stock, I have deleted the file PRF2SAFE.RCV only on the user partition

    well thx, but still not working for me :/
    on USER partition you did erase all the contents in the folders, meaning you have just:

    Album
    Contents
    save
    saveMeta
    temp

    which are alle empty then, except Contents which has the subfolders
    placehld
    registered

    which you also emptied, or did you also delete those two folders?

    I have deleted everything from the user partition including folders

    many choidoujur problems are caused by the keys.txt file used, if you use lockpick your file should be fine to restore version 1.0.0, you could try it and see if you can boot your switch, just make sure to use --noexfat when building the firmware and use a fat32 formatted card, good luck my friend

    yeah, I already thought about trying to flash with 1.0.0 release-version once more, and I will give it another try, but honestly I don't see why it should behave any different from all the other firmwares I have manually installed via ChoiDuJour. Already tried with 6.0.0, 6.0.1 and 6.1.0 several times.
    My keys are fine, I had also a very experienced guy doing a built with 6.1.0 on his own with my keys and I flashed it - still stuck on flashing atmosphere logo.
    I think I might have to talk to the atmosphere guys and ask them for any helpful information about this 1.0.0-7 pre-release version. There might be sth. still different, I don't know.

    There is another thing you can try, download auto xbins (look for it on google the antivirus may report it but it is safe), start it and wait for the connection to be established (it may take a few minutes) when you see the folders go to / SWITCH / CFW / _CFW Tools / Unbrick Your Switch Pack /, download the 7z file, unzip it and follow the instructions contained in the Brief_instructions.txt file. It is a firmware 6.2 pre-built with a boot0 / 1 restorer, I hope it can work

    extremely interesting Alerappo, thank you very much for these incredible hints!!! I was like: a 6.2.0 what the heck? awesome!!

    I did all the steps successfully - now the console is able to boot atmosphere, then nintendo logo appears for three seconds, but then still just a blackscreen. I will give it some more tries soon - at least I am one step further now - this is really getting more and more interesting :D

    Keep you updated, if I'd succeed any time. nice post, though, mate!

    I'm glad to hear that, keep trying I'm sure you will be able to solve, try also to restore the nand and repeat the procedure, but before copying the archive folders to the system and user partitions, delete all the files and folders you have inside the partitions of your switch (PRF2SAFE.RCV too)

    Awesome, good job my friend

    did a few more NAND restores and with this method now I am always getting until atmopshere logo (all folders cleared from every data before copying the 6.2.0 files, also PRF2SAFE.RCV files in SAFE, SYSTEM and USER was killed), then nintendo logo for 3 seconds, but then I am still stuck with blackscreen :/.
    also tried the BOOT_REPAIR_PACKAGE found in xbins, but when flashing those "keyblob_killer" boot partitions, it won't boot at all ("key verification error"). Not sure what I am doing there, so I returned to the described boot loaders.
    But there is still something missing I guess - feels like just one last tiny step :D
    Won't give up, but without ideas for the moment, once again.

    Will try again with keeping the PRF2SAFE.RCV file in SAFE partition, as you didn't mention killing this one.
    It is the only file stored in the SAFE partition of my NAND backup, though. Let's see

    I am not sure, but I guess 11 - last OFW was 9.x.x, so this amount of fuses would make sense, at least.
    I guess I would need a NAND fw from 9.x.x too?
    What was yours before / how many fuses do you have burnt?

    Is there a way to create a NAND with ChoiDuJourNX on a working switch and extract these files to use them for the bricked switch?

    my switch haved
    yep, you need the firmware to launch the OFW, and from there, you can update... i have 13 fuses burnt, so i needed the firmware 10.0.0 to 10.0.4 to make it work.

    you mean updating to 10.x using ChoiNX?
    I just have the 6.2.0 firmware-files from Alerappos post and by flashing that, mine still won't boot. So I thought, I might have to flash a 9.x or 10.x via HacDiskMount, but I have no idea how to get my hands on those offline firmware files..

    You can try to upgrade to 8.10 with this modded version of choidoujour
    https://github.com/D3fau4/ChoiDujour/releases
    Good luck

    hekate -> Console Info -> HW & Fuses says:

    Burnt Fuses (0DM 7/6): 11 - 0

    So I guess the answer would be 11 fuses burnt.
    And where do you get these firmware files from? How could I generate them?
    Thank you in advance, though
