    Hello All,
    I need your help for my switch. I can't boot anymore neither the original firmware or the custum one (sx Os).

    Previously I had the following setup on my switch:
    - Emunand installed on my switch, no auto rcm installed. I'm using SX Os.

    I have updated my firmware with choidujour but unfortunally I have choosen the autorcm option (like the other time I have made updates). After this update I was not able to on my custom firmware on the original one. So I wonder if the Emunand was problematic so I made the (bad) decision to erase the Emunand from os option. Now I can't boot anymore, I'm only able to boot on SX boot menu then I have a black screen (original & custom firmware).
    Can someone help me please ?

    If you had Emunand installed, and you updated with ChoidujourNX, then you probably updated the emunand. By deleting it, you just removed your CFW, and your sysnand should still be OK. I would try to remove autoRCM with the SX boot menu. Worse case scenario, just re-install your nand backup. You made one, right? Right ?!?

    Many thanks for your advice, yes I have made a backup (long long time ago) with the Keys. I will try your different advice and let you know the results.

    anytime, backup boot0&1 and system at least. don't worry about old version becuase the cfw can skip efuse to run Hos.

    Hello,
    I have reinstalled the emunand as suggested, now the original firmware boots, but the custom one not...
    Do you have an idea to make it boot ?
    Regards

    hos 10.0.3 ? replace sxos 2.9.5's boot.dat on your sd card root.
    then delete folder path as sxos/titles/ is better.

    don't mention it. backup your console's clean rawnand is enough.
