    Here are the steps that come to mind:

    1. Open Hourglass9
    2. restore Nandmin (the guides stock 9.2.0 back up) to emunand
    3. Open Decrypt9 on the new 9.2.0 emunand
    4. Restore Sysnand to Nandmin (Without A9LH)
    5. A9LH is gone? On stock firmware? Can now boot without SD card?

    Are these the correct steps?

    I know that. I am asking if the process I listed would be the correct one.

    You can do that with A9LH.

    I'm aware of that. Which is why I was hesitant to make that a point.

    Why bother with the emunand thing? Decrypt9 can be booted straight from a9lh.

    check the Luma payloads folder. I believe Plailect's guide sets you up with it so it should be in there.

    So put the decrypt9 payload in there. Luma's github info tells you how to bind a payload to a key but it may be obvious already.

    Yep, just stick "x_" at the front of the name to map it to x on boot.

    I advise making backups of the NAND with a9lh and also the OTP before uninstalling a9lh.
