thanks again for the info. i just charged up one with legit/unmodified 4.5 FW on it and it wont even let me log out/remove user/unlink account without wanting to go online and download an update for the switch. yikes.
I feared that would be the case, yeah. Nintendo wants you to update to the latest firmware before you do anything.
i wanted to reformat this switch that is still on legit 4.5 firmware and then hack it but now it seems like i need to hack it first or let it update before i can wipe it?
edit: i am looking into re-initializing the console from maintenance mode(power+/-volume) but it says i should only use this under exceptional circumstances in bright red. hm.
edit 2: re-initializing from maintenance mode worked, now its back to factory default and still on the old original fw. thanks.
Glad it worked out for you, I was in a middle of writing a bit lengthy reply but you were much faster. ^^
Now that your console is factory reset, I'd suggest that you set it up the way you'd like it to be so that the personalized settings carry over to the emuNAND once you create it. I'd suggest that you delete all saved wireless connections and disable automatic software updates and sharing error information. Before you make an emuNAND, make sure not to connect to any network while on stock firmware i.e. your unhacked system. You don't want your emuNAND going online without previously setting up 90DNS or DNS MITM in order to block Nintendo servers.
Optionally, I'd suggest that you pick one theme that you prefer
less (Basic White or Basic Black) than the other one to use on your sysNAND, and use the one that you prefer once you get into your emuNAND. That way you can easily differentiate between the two which one's which. I like to keep the white theme on my sysNAND, and the black theme on my emuNAND. I don't mess with the custom themes personally as the default ones work perfectly fine for me.
Once done, make a full NAND backup. This will be your clean NAND backup. The steps to do so can be found
here. Keep your backup somewhere safe! It's really important to have one if things go south.
Maybe wait for someone else other than me to reply as well, but I believe that once you make a full backup you're safe to format your Switch, if you really want. You can always restore the backup you've previously created if something doesn't work.
Now, I'm not sure how would you go about connecting to your NNID without updating your system. I can think of a way to do so, but I'm not sure if you risk getting your console banned in the process. Probably not worth the trouble.
@Draxzelex mentioned that it's possible to
update sysNAND without burning fuses, but I'm not sure what's the proper way to do so i.e. the risk-free one. Maybe he can comment on that further. Linking a fake account on emuNAND with
linkalho shoud be enough for the most use cases, e.g. being able to play official NSO emulators for GBA, N64, etc.
Since you're probably new to the Switch hacking scene, I'd suggest that you go through these two guides:
NH Switch guide and
Rentry.org Switch guide. Getting familiar with the terms used will make updating and maintaining your Switch afterwards a much easier task for you.
I've made a short tutorial
here about updating your Switch CFW environment, hopefully it'll be of use to you.
And that's pretty much the extent of the info I can share with you. Keep your SD card and your setup as simple and organized as possible and you'll be good to go. Good luck!
Is it necessary for me to copy across the kip_patches and exefs_patches folders over to my Atmosphere folder also? These are also contained within the Sigpatches zip file.I figured since I have the sys-patch module installed, these wouldn't be necessary, but I could be wrong here?
I believe that they are unnecessary if you're using sys-patch. You can even launch the official fusee.bin in order to boot into Atmosphere and, if you have sys-patch only, game backups should work. patches.ini comes bundled with sigpatches so I don't think that sys-patch need them.
