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

I have BTOW with latest patch on my 8.1 sxos and i use my personal backup xci file of it.

your not using the file that was on sd card that got corrupted? as just changing the format of the card isn't going to fix the file once its corrupted

why not make a new backup from the retail cart?

 

Ok. Don’t panic people. I’ve formatted my sd card and tried again. Again it said it was corrupted. I then deleted the Zelda update data that was on my switch and reinstalled the latest update. Launched the game without any issues.

Panic over!

 

I want to reinstall firmware 8.1.0 in my EmuMMC and do a factory reset but it gives me an Error 0x805, please help!

 

If you had usb access to the emummc while its not in use you do the reset i used to clean the nand

in system partition

in "save" delete all except 8000000000000120
in saveMeta delete all except 8000000000000120
if anything in Contents/placehld, delete all in placehld also.

in User partition
delete everything

delete sd folder

Done.

or

use hekate to restore a nand backup to the emummc which would overwrite everything

 

I just finished setting up my 2.3 OFW switch with Atmosphere/Hekate emummc. I'm looking to update my emummc to the latest firmware and I read this is the tool to use.

Does the bullet point about never running firwmare above 4.0 and gamecard updates apply to emummc? I plan on keeping my sysnand on 2.3. Not sure if this is actually an issue, just making sure

 

1. If you update your gamecard slot, you will be unable to use cartridges on your 2.3 sysNAND, and you will be unable to downgrade your gamecard slot.
2. If you don't update your gamecard slot, you will be unable to use cartridges on your 8.1.0 emuNAND.

 

Thanks @Lacius. Interesting dilemma

 

i have a console in 8.1.0 and i wanted to add exFat support
the app getting error

can anyone help

 

if youre on 8.1 just go online and put an exfat larger size card in and it enables their use on the console...i thought that was the whole point?

EDIT: dont mind me, im thinking of sdxc support. I cant help you with this thing, sorry

 

Hi. I'm trying to update the emunand offline to 8.1 version, but the ChoiDujour 1.0.2 doesn't recognise the firmware folder. Can you help me? Thanks!

 

What do you mean doesn't recognize? Can you analyze it? It must be a folder with NCA files extracted.

 

so I accidentally booted into cfw sysnand on a 4.1 ipatched system and upgraded my sysnand to 8.1

TOTALLY my fault I know but would there be any way to add a warning if you are about to flash to a sysnand?

 

Will I need to use this on my banned switch, if I need a future system update?

 

Probably not, bans usually don't block sysupdates

 

Well that's good news, thank you!

 

Not that it matters, though. Doing this method is easy enough, and the firmwares are not that big in size.

 

I'm on firmware 3.0.1, is it safe to directly upgrade to 8.1.0? (or is it only 8.0.1 that's supported?)

 

All firmware versions are supported with ChoiDujourNX.

 

I'm on firmware 6.0.1 do I need version 7 keys to update to 8.1.0? Or anything else?

 

You can update (or downgrade) to any firmware you want.
