I have a problem, I have done everything correctly without any problem, but now when I leave my switch in standby it turns off by itself, and when I try to turn it on only with the power button it remains in black screen
What can I do?

Hello,

I'm trying to use choidujour for firmware 5.1 but i keep getting the errors

ChoiDujour.exe --keyset=keys.txt fw

ChoiDujour 1.1.0 by rajkosto
uses hactool by SciresM (https://github.com/SciresM/hactool)
visit https://switchtools.sshnuke.net for updates and more Switch stuff!

Using source firmware files from folder fw
Traceback (most recent call last):
File "ChoiDujour.py", line 517, in <module>
File "ChoiDujour.py", line 225, in call_hactool
Exception: Error: section 0 is corrupted!

[15216] Failed to execute script ChoiDujour

In fw folder are the files from firmware 5.1, i think i'm having trouble with finding this populated keys file from hactool, i cannot generate it myself since the firmware of the switch (bricked else i would use choidujouNX) is 6.2+ and for exemple this tutorial : https://gbatemp.net/threads/how-to-get-switch-keys-for-hactool-xci-decrypting.506978/ is not working, i tryed it just in case

I found a big keys.txt online and when i try it i get this error

ChoiDujour 1.1.0 by rajkosto

Anyone can help me out please?

Thx

I just checked and I have 10 burnt fuses. Is that bad? How do I not burn anymore?
10 fuses means your sysNAND must be on 8.1.0 for it to boot properly, and it means nothing can ever be gained from a downgrade.

To avoid burning fuses, either don't update your sysNAND or keep AutoRCM installed at all times.

Hi All

Need some advice here. My friend used this method last year to get me from 4.1 to 5.1 which I have used ever since.

As my son wants to play the latest games on 8.1 offline what are my options?

1) am I best reverting to original 4.1 and then using sxpro emunand. If so how do I revert back to original?

2) use another method to update to 8.1 keeping the same setup? Ie RajKs other method? If so where do I start from there? Lol

Apologies for these questions as I’m new to all this and my friend has moved away from the switch scene.

Many thanks

Since this program only supports up to firmware 6.1, you will have to use the homebrew application ChoiDujourNX to update your firmware instead. You do not have to revert your firmware in order to use EmuNAND.

Hello.

I have 9 burnt fuses. Tried to update with sx os to 8.0.1 from 7.x and it froze. Had to reset the switch and now it goes to black screen after launching CFW. Tried to use this guide to do a manual downgrade to 5.1.0 and to 4.1.0

Bot times I completed the guide with no issues (that I know of) but when I try to launch Atmosphere it gets stuck at a splash screen that says Kosmos-something. Am I doing anything wrong? any help is appreciated, thanks

EDIT: I lost my backup files for nand and boot0/1
