    You need to make sure both straps are correctly fitted and use version 2

    The joycon and vol+ strap. You need those fitted to have fully automated CFW boot without autoRCM.

    Just tested. Working fine?

    Needs updating to Hekate 4.5 though. But it works perfectly.

    Updated OP with fresh download links.

    Are you following the correct procedure for updating the chip?

    Disconnect from USB
    Double press reset until light is breathing
    Connect to USB
    Flash uf2.

    OK... Bit of an update being pushed either tonight or tomorrow.

    For single payload users...

    No 0 folder required...

    UF2 will either boot "payload.bin" or "start.bin" by default. Can be any payload. Will look on root of SD

    If they don`t exist, Hekate will boot. No folders or anything will be made.

    Nothing else required.

    Any good to anybody?
