No but there is a way to preserve your 1.0 and play your game. The answer is to update your firmware without burning fuses. Fuses primarily are designed to prevent downgrading but there is a homebrew application named ChoiDujourNX that can put you on whatever firmware you give it without burning any fuses. How it prevents fuses from being burnt is that it enables AutoRCM after installing the firmware. AutoRCM, as the name implies, causes the Switch to AUTOmatically enter RCM. It does so "bricking" the Switch but its an easily reversable brick. With AutoRCM, you cannot boot the Switch normally; instead you will have to send a payload to use the console so if you don't use sleep mode or turn off the console a lot, you may have to change your habits. Another thing to note is that with AutoRCM, turning off the console will cause it to reboot into RCM. This is only a minor inconvenience as it is still possible to turn off a console with AutoRCM. All you have to do is power it off from RCM. Options include a manual shutdown in RCM (holding power for 12 seconds) or using the Power Off function in Hekate which involves sending Hekate as a payload.
Thanks again for the very thorough explanation. I’m new to these forums (and to the Switch scene as a whole), and I can already tell that you’re extremely patient and helpful in your replies, not just to myself.
I’ve been doing as much research as I can, but I still have some questions, as most of these concepts are alien to me and I’m still getting used to the terminology.
Regarding AutoRCM, I’ve read about some battery draining issues, have those been addressed/fixed? I will mostly be using my Switch docked, so I assume it’s best to just always keep it in sleep mode? And if I do power it off using any of the methods you mentioned, does that turn off AutoRCM and make the console boot into the OFW? I really don’t want to risk burning those eFuses.
Also, in my thread, someone mentioned a method to backup the NAND without the need of a jig or dongle on 1.0.0, using something called a pegaswitch script. Would I be able to update the console without burning fuses thought that method, as well? I’m just looking for the fastest way to play Mario Odyssey without losing my Switch’s “virginity”.
There are some other issues that still confuse me, like the game cart and exFAT updates. Apparently, I’ll have to update to exFAT regardless (especially since my cards are 128GB in size) and after updating the firmware even without burning fuses (offline), I won’t be able to play physical copies of games anymore?
