And, after the 3DS got its recent system update, this time it looks like it's the Switch's turn. Firmware 9.1.0 has been released by Nintendo for all regions and the changelog states it's meant to fix an issue with the colour animation not showing correctly when attaching a Joy-Con to the console... alongside with the usual stability. However, there may also be something else under the hood, as @SciresM has warned that TrustZone might have received an undocumented change, so current CFWs may break if you install the update.

Ver. 9.1.0 (Released December 4, 2019)

General system stability improvements to enhance the user's experience, including a solution for the following:

• Resolved an issue where the color animation was not displaying correctly when attaching a Joy-Con controller to the Nintendo Switch console.

On a Wednesday :(

Looks like TrustZone might have updated -- if it did, I'll stream diffing later tonight. https://t.co/0CfRnFkgY8

Needless to say, given those premises, it may be best to avoid updating for the moment if you're running a CFW or if you wish to mod your console. Not much else is known at the time of writing - this post will be updated with any useful hacking and homebrew-related info.

EDIT: For devs (and the curious), a summary of the TrustZone changes by SciresM found in FW 9.1.0 is now available here.

EDIT 2: SX OS, Atmosphère and Hekate have all been updated to support firmware 9.1.0 since then.

Okay so I used atmosphere to restore my NAND and enabled auto rcm this is a work around until the new update. Please see the guide here if u have any questions I don't know a lot about this but make sure u enable auto rcm

It can work fine but it won't until Atmosphere / SXOS updates their CFW to work with sysNAND 9.1.

emuNAND can be whatever version, since its emulated.

your system nand needs to be 9.0.1 or under as of today AFAIK to even load emuNAND.

My Emunand works. Sysnand 9.1. Emunand 9.0.1. SXOS. I'm not sure about booting directly to CFW though, as I use emunand exclusively for Homebrew and such, and keep my sysnand clean for online.

I knew this going to happen, its been awhile since they updated -_-

 

[godreborn]

for some reason, when I updated, the system rebooted to high-pitched static followed by messed up sound effects on the home screen. resetting the system seems to have fixed it, but what could have happened?

mom said it's my turn to update the switch
im waiting for the incoming help threads

 

[hippy dave]

Warning: my joy-cons only display their original colours! If you use the app to change colours it does not show them anymore.

Oh shit, for real? If so I hope CFW can fix this at some point.

Any hope for an improved SD-Driver?

No, Nintendo won't fix it because it doesn't often cause problems for official software, only for homebrew. Ignore the people saying there's no problem, they've just been lucky so far.

What are the odds!

Since I'm not an idiot (all of the time) I'll just continue enjoying puzzle quest for the umpeth time. Switch save at 60hrs+.

I am scared to check my playtime. But lately Evoland refracted me, which is good I guess. Anyway PQ is addictive, like crazy. Whats your lvl?

Let the record show; I'm on the pooper in a cruise ship off the coast of Chile reading this.

What is the problem that some people are having?

Data Corruption. But I don‘t know what’s the real cause. Some people blame Nintendo, other ones claim it’s not. I’m confused

 

[pokerusZ]

Subscribing/watching to see how to fix this.

Also wondering if we can roll back to 9.0.1 in the meantime

nooottthhhhh

Nintendo didn't follow spec when implementing the exFAT driver. Homebrew devs followed spec. The solution to fix the problem would be for the homebrew devs chose to fix the compatibility by implementing the spec Nintendo used or if Nintendo chooses to go back and use the actual spec. You can blame Nintendo for going offspec or blame the homebrew devs for not using the spec Nintendo used. Your choice.

Per the emulation developers mindset the proper thing to do would be to implement compatibility with whatever Nintendo did and not blame the fact your stuff isn't compatible with Nintendo based on the fact you didn't use the spec Nintendo did.

The "work around" in the meantime is if you're a CFW user to not use exFAT and use FAT32.

 

[Hephaestus]

you can update your games offline yourself with nsp file updates. You don't need Nintendo to update your games unless its an online only game
Where to get these nsp updates for your games? Google my friend or the sites you been getting pirated stuff from.

Yeah, that answer had nothing to do with my question at all.
I already found out that the new firmware comes with new crypto.
So unless we get Custom Firmware support for 9.1.0 we cant run anything signed with the new keys.

Do you guys think if I don’t update my ipatched switch this time I will be able maybe in the future to hack my switch?

No idea, if you want to hack so go find hacked Switch on Ebay.

 

[Diogo097]

Maybe a hardware mod hack will came around or something, what do you guys think, besides the logical solution to risk and buy one in eBay?

This might be an option soon: https://gbatemp.net/threads/more-info-regarding-switch-mariko-lite-mods-by-team-xecuter.551848/

And might be better to stay on the lower firmware for that.
