    This Multi-Guide provides instruction for the following:

    Back up your NAND,
    Backup your system information,
    Restore your NAND,
    Make exFAT work on lower system versions


    Please read and follow the following disclaimer before attempting to follow this guide:

    Only use the files attached, I update these when needed to ensure that they are functioning. Failure to use the attached files may result in issues.

    I take no responsibility for issues you may have as a result of the use of the files or instructions contained within these guides. You execute this/these guide(s) at your own risk. I'm happy to help with any questions. Please review the comments and answers on this thread as well. I try to provide assistance when requested.

    Before any modification of your system, I recommend you back-up your NAND (to make yourself a clean back-up and/or a virgin NAND). Don’t use Auto RCM until after you complete your back-up.

    To follow the below guides, you will need the following:
    • A micro SD card formatted to exFAT or FAT32 with at least 32 GB of free space
    • All files attached at end of this guide, extracted to your PC
    • Fully charged Switch (or the ability to keep the Switch plugged into a power source during the restore process)
    • USB to USB-c cable (short is better)
    This guide assumes you have some method of entering into RCM. (e.g. RCM jig installed or shorting pins 1+10 on the Joy-Con rail.)
    You may also run the "Hekate.bin" from your own dongle or method from the
    "Payloads to be used with tegra.zip" if you do not wish to use TegraGUI

    Restore Nand Guide
    I take no responsibility for issues you may have or if your system fails to boot after restoring your NAND.
    You do this at your own risk!

    Please make sure to read the blue text in my Backup guide above when you made your backup

    To follow the below guide, you will need the following:

    Make sure your battery is charged (at least enough to complete the restore process) or keep the switch plugged into a power source (USB cable should be fine)

    I read somewhere that there is issue while copying backup nand in Windows 10. If I recall correctly, the message was by @Draxzelex. So, was there any such issue @Draxzelex?

    Certain builds of Windows 10 don't transfer the archive bits properly which is needed for the way Horizon operates (chicken and egg problem here). Forgot which ones they were, but if you use a 3rd party program like Total Commander, the files will transfer over without any issues.

    Folders transferred from a computer running those builds will not carry the archive bit over which is needed for the Switch to display them. Either set the archive bit after transferring them or use a tool such as Total Commander that won't remove the archive bit.

    In short, it affects all folders transferred to your Switch or an SD card inserted into the console.

    The keys.txt in this guide will get you your 70ish or more keys from your console,which you make from your system and no one elses to use for what ever you wish

    if you want to get exfat without updating etc maybe this guide will help you

    Yes, you can do that but most people typically extract files before transferring not after. If you instruct them to move the compressed files first, I suppose it would work as strange as a suggestion that is.

    maybe this is a stupid question (been loosely following the switch scene), but what's the point in staying on lower firmware if sx os works on the latest? I'm mostly referring to the fact that you need to go through a guide in order to get exfat working. :unsure:
