    Thanks to Caffeine, I managed to jailbreak my 4.0.0 Switch, and created an emummc. If I update the emummc, do the efuses get burned?

    Updating never burns efuses.
    What does is the reboot after the update that boots into Nintendo's bootloader (right before Horizon boots up).
    And that bootloader checks (and in case burns) fuses.
    Long story short -> if you're always booting the EmuMMC through hekate you won't burn fuses (as hekate replaces the bootloader from Nintendo).
    However, if you update via ChoiDujourNX be sure to uncheck the "enable AutoRCM" option or you end up bricked on an ipatched unit!
    NEVER activate AutoRCM there!

    If you didn't understand everything I wrote, rather keep asking instead of trying something. Ipatched Switches can be bricked easily by messing around.

    Do as @lordelan suggested above.
    Still you should proceed with caution. ipatched switches are a bit tricky.
    While updating ensure your switch has enough battery left. if not charge it beforehand and get around to updating it later on.

    What is usually suggested is to use a dark theme on emunand, and a white theme on sysnand (or the other way around). Then you know right away if you're in sysnand or not.

    That doesn't work for me. I set the white theme in emummc. But it is white in sysnand after rebooting to it. Now i don't know if i'm in sysnand or emunand.

    I don't have an ipatched switch but if you boot on emummc with a CFW you can check in main menu Options > Console > Version
    It shows me 8.1.0 (AMS 0.9.2) so i know i'm on Atmosphere

    Then change one of the themes to a different color lol. I do this it works easy to differentiate between stock and cfw.

    This is not an indicator for emunand.

    The new version of choidujoirNX 1.0.2 has a built in option BY DEFAULT it DISABLE the AUTO RCM feature for iPatched switch.

    But while upgrading any cfw we should pay close attention to these small details.

    I do have iPatched switch with OFW 4.1.0 on which I used pegascape Web exploit to launch HEKATE.....

    Through Hekate i created a emuMMC partition ( separate partition not the SD FILES )...And I have updated that emuMMC to 8.1.0 with the help of choidujoirNX)

    Separate guides are available on choidjoirNX process of upgrading the fw.

    So finally I have iPatched switch with synand at 4.1.0 and emuMMC at 8.1.0(and 0.92)

    Till date nobody clarifies these things for noon like me.

    yes it will, preventing burn efuses because you dont use RCM mode

    You have no understanding on how the switch's bootloader works
    Deja vu reboots to a payload of choice for example hekate
    Hekate won't burn fuses dumbass
