    This is what I needed. Is there any way that the eMMC can be started as USB by just starting the Payload without MicroSD needs?

    yes, see cmdline args of new 1.2.0 TegraRcmSmash (you just need to pass the full ini path to --dataini= parameter)

    I already made the process and I left a message for you privately. Anyway, the HacDiskMount program keeps closing when I try to open the physical unit. Although in Disk Manager Windows 10 I see all the drives. I will try to use another program like the one mentioned above to have such.

    Captura de pantalla (128).

    I see that the only difference is that the state of the user who has the problem says offline, and that of rajkosto says Online.

    An error occurs in Device Manager that says "Disabled (The disk is offline because it has a signature collision with another disk that is connected)

    I REALLY hope people have a full backup of their eMMC before doing this, or at least it is read-only, and mounted under Linux only. Otherwise I can see this being a cocktail for disaster. Windows does not natively respect Linux file permissions, and third party FS drivers have been known to corrupt them.

    Besides that, this is a really great / useful payload.

    Is there a downloadlink for the payload? I couldn't find it on the website.

    EDIT: found it, I had to delete my browser cache.

    This is still the best way to do it in my opinion:

    ICfjxD.

    Costs a whopping $4 with free shipping from Odroid on Amazon.

    It uses the same connector as the Odroid emmc cards? Didn't know that.

    Yeah, they just used an off-the-shelf eMMC chip from what I can tell. It's just encrypted. Good enough to dump the NAND with.

    NO, those don't work. Don't tell people to buy things when you havent verified them yourself.
    ODROID uses 17x2 pins with a completely different pinout from the Switches 15x2 pins, which is why i had to make my own:

    some reliable link of what do we have to buy?

    and congratulations and thanks for sharing this, I think a lot of people were looking for it. Now it's the part of being able to load from there things like xci or nca if you do that you'll be the first to make history of the big ones

    There's nothing to buy for the Switch, even if i posted the gerbers for the pcbs you would need to fabricate min 10 of them and the connectors are also expensive and a pain to solder on properly
    just use the UMS modes, let the switch do all the work.

    I managed to make a backup of the partitions like RawNand.bin using the HxD text editor. To do this I had to run it in administrator mode to detect the units. It took approximately 2:25:00 (Two and a half hours approximately).

    I also have a tool called WinHex, with which it detects all partitions of the Nintendo Switch eMMC. It allows to duplicate physical units in others perfectly. It would be useful to mount a unit with HacDiskMount and duplicate that Unit with the corresponding partition of the Nintendo Switch. I have not done it, I hope that @rajkosto tells me if you can write to the eMMC without damaging the Partitions.
