    Hi guys!

    I saw that in theory if you use a CFW which disables fuses, you can use any firmware you want. To test it out I installed 1.0 via ChoiDujourNX, and since that I can't boot my switch. RCM works, but I tried to boot from SX OS and ReiNX, both of them didn't work. I tried booting from OW, but it gives me an error message 2002-4315 error message probably because of the fuses. I installed the non-exfat version of the FW previously I used the exfat versions and I have my SD card formatted to exfat if that matters.
    Is there any way to get the 1.0 to boot or to roll back to 6.0.1 or 5.1.0? I also don't have any backups unfortunately.
    Thanks for your help in advance!

    Always, ALWAYS make a NAND backup when messing with NAND. That shouldn't even need to be said.
    But I think you can use ChoiDujourNX to update it.

    How? To use ChoiDujourNX, I have to boot the homebrew menu. Now I can only go into RCM

    AFAIK the 1.0.0 files are not working. So you can't get back to that version.

    Original from rajkosto:
    • Extract the UPDATE partition from an XCI image of the cartridge that contains the update you want into a folder
    These are common cartridges and firmware versions they contain:
    Puyo Puyo Tetris/ 1-2 Switch (1.0.0) - would never recommend installing this one as no Switch made with 1.0.0 actually runs it (its a slightly different 1.0.0 with exFAT that bricks you)

    Anyway you can ask him to try to put you into the right direction. (He is very helpfull!)

    Thanks for your help guys, so far I managed to dump my SBK and TSEC keys and I dumped the BOOT0 and BCPKG2-1-Normal-Main files from my switch in order to dump the keys. However when I launch the python script it fails with an error message: Could not find sd_card_kek_source! Please check the integrity of the data used in the current stage!
    What should I do now?

    I'am sure you do your best.....but i think you should contact @rajkosto because he is the writer of the tools. And he can tell you what to do before you got into worst trouble!
