    I was on a 8.1.0 stock Sysnand (with a backup copy of that)
    While using 8.1 Emunand (file-based), I was freaking careless to press the update button before launching a title.
    That's when the nightmare started - update proceeded and black screen rendered.
    After a black screen for 5 min, I force power off my switch, trying to reboot.
    1. Kosmos
    2. Sept
    3. atmosphere
    4. triangle shape
    Finally gone black and wouldn't boot.

    I updated my stock Sysnand to 9.0.0 to see if it could help boot into the Emunand, also could not boot into Emunand.
    Then I tried some solutions:
    a) migrate Emunand using my 8.1 backup =================> Succeed, booted into 8.1 cfw Emunand
    b) create new Emunand (file-based) ======================> Fail
    c) create new Emunand (file-based), on another SD card ======> Fail

    Could anyone suggest a way to ,at least, make a new Emunand ?:cry:

    Do you have a game cart in your switch? If so, try to remove it. It fixed it for me. I guess it has something to do with 9.0.0 updating the game cart controller.

    Are you using the latest build of atmosphere? The one that supports 9.0.

    try just grabbing atmosphere from their github.. if 8.1 emunand boots and 9.0 doesnt, something is wrong with your files
