Homebrew RELEASE ChoiDujourNX - a system firmware installer homebrew for the Nintendo Switch

[Pluupy]

I'm kinda confused on how this works.

So I have a 3.0.2 Switch and do not have exFat update. I have a 32gb fat32 sd. I have backed up my nand and successfully ran atmosphere to look at homebrew menu using tomger's sdfiles.

I want to use this program to update firmware to 5.1.0 and get the exfat update.

I have the 5.1.0 update files from xbins, but don't know how to actually use them. The readme of choidujornx says I need to drag the update package to the choudujour.EXE but it opens a CMD window really fast and instantly closes.

Am I doing something wrong?

Edit:
Oh my goodness I made a screenshot as the window popped and captured this. I guess I was putting in too many! But how do I use it? I have a lot of .nca files.

ChoiDujourNX is a homebrew, ChoiDujour is a PC application. Either way, extract the zip you silly. Then use the folder with the homebrew. The homebrew installs it all automatically, I don't think you want to mess with manually installing everything from the generated ChoiDujour PC files.

Did anyone of you who was already on 5.1 succeed in installing only the exFat driver?
Everytime I put in my 5.1.0 folder (with which I updated back then following raj's long guide) and hit exFat it starts some scanning and tells me "205/207 - no meta found for nca ..." something like that.
Is my 5.1.0 folder incomplete?

That's right, you dont have the exFAT part of 5.1.0

I want to dump my nand before doing anything suspicious. Do I have to install the exfat update before? Or Hekate supports exfat microsd without updating?

 

[rajkosto]

Hekate works without any OS whatsoever, so it doesnt care if you have exfat in Horizon or not.

So the update folder I downloaded from xbins is all that I need for the homebrew?

 

[rajkosto]

Yes. Just choose it.

Does choidujounx have built-in no gamecard? I'm really nervous about this. I know ReiNX had that thing but I have no idea if anyone else does.

Yes. Make sure to use the "preventGCupdate" entry in the rej payload after completing installation whenever you boot.

Edit: In fact there's two entries, one being "stock preventGCupdate" and the other being "CFW preventGCupdate" which you're obviously going to use most of the time. Don't ever use any other entries or even delete them from your ini when you're done.

Edit 2: It's even in the OP dude. Second last question in the FAQ section.

So when I boot hekate and see that big list of firmware booting options, I select "cfw preventgcupdate"? Thank you so much. I literally lost sleep over this.

Slightly OT but does anyone know the reasoning behind why french has been adopted as the language for releasing switch related hacks and home brew? Of all the languages French??

Yep exactly. If you use ChoiDujourNX you should end up with an adjusted ini (ChoiDujourNX automatically does this to you) with those preventgcupdate entries and you must chose them from then on.
So be sure to back that ini up before you ever overwrite it in case you're updating hekate or something like that. Just stay with that ini and use those prevent entries to either boot stock or CFW.
I brought a friend's Switch to 5.1.0 (which was 3.0.2) with ChoiDujourNX yesterday and everything worked well. I edited his hekate.ini to have the CFW prevent entry on top and now he's good to go.

Btw @rajkosto this homebrew is so well made. I looks fantastic, runs stable, takes care of everything and makes it as simple as it can get. Your best work I'd say. Thx for that.

In the 1700s, I believe French was the "language of business" much as English is now. France used to be the superpower of the world. THE place to go for trade. I don't know why homebrew people are using French. I think they're either actually french or pretentious.

This homebrew program is a Matrix reference, I think though.

 

[andyhappypants]

Cheers, I was aware of Frances history of being a superpower but am struggling to understand why the hell homebrew is named this way. I’m also going with pretentious

I don't recommend using cartridge 1.0.0 anyway because its a different firmware than shipped 1.0.0, and one that no console has ever had installed before i made ChoiDujourNX.
The shipped 1.0.0 is a better choice (and doesnt even pretend to have exFAT), you can get it from the place that has all the firmwares.
Why do you want to run 1.0.0 ? It can only play a few cartridge games, OS is incomplete for anything else

So say i wanna go back to 1.0.0 i should use nand restore in hekate instead yes?

 

[Meriadoc]

your bootloader should have warned you that no microSD is inserted, and if you wanted to proceed booting pure stock (which will update the gamecard controller but not burn fuses)

No message at all, even the first time I boot with Hekate the ini file from choiDujourNX I can use the cart slot . Maybe I should have used the modified Hekate I don't know.

However why is so important to not update the cart slot ? In the future will I have problems for this ?

what is preventGCupdate?

 

[LeMageFro]

what is preventGCupdate?

Reading OP is hard.

• Q: I've never run firmware 4.0.0 or higher on my switch, so my gamecard controller firmware is still not updated. How do i make sure my gamecard controller works after i downgrade back to < 4.0.0 ?
• A: When flashing the firmware image for any 4.0.0 or later firmware, ChoiDujourNX will generate a protective hekate_ipl.ini on your microsd, with a "PreventGCUpdate" launch target. You must ALWAYS boot using this launch target (or add kip1patch=nogc to any launch target you wish to use in the future) and use a Hekate that supports the kip1patch option (releases here do: https://github.com/rajkosto/hekate/releases) if you want to prevent use and updating of your GC controller firmware on firmware versions 4.0.0 and up.

If you want exFAT, just pick the (exFAT) version of the firmware when installing it via ChoiDujourNX. Never use the official firmware updaters as they will remove AutoRCM and burn fuses on reboot.
Since your intention is to play your original games, do you mean they are cartridges ? To use cartridges on 4.0.0+ you unfortunately HAVE to let the cartridge controller update, so you would NOT be using PreventGCUpdate options.
However if all your original games are from the eShop, you must use, and keep using PreventGCUpdate launch options forever (stock or CFW).

Yes, my games are on cartridge, so... my only option is to update normally? (I entered on the "Stock - PreventGCUpdate" option after doing the NAND backup and the console read the cartridges, that´s the reason why I was thinking that I can update to 5.1.0 and use the "PreventGCUpdate" option)

Edit: nvm

 

[rajkosto]

You can still use cartridges on 5.1.0 but if you're preventing the GC update it's slower than usual.

No you cant. If you want to use cartridges you gotta not Prevent GC update, which will update your cartridge controller and let you use carts on 4.0.0+ but never again on < 4.0.0
