Both the Nintendo Switch and Nintendo Switch 2 have received an official firmware update. System software version 20.4.0 has rolled out to consoles, and you'll never guess what Nintendo tweaked with this brand new update: "General system stability improvements to enhance the user's experience." Scene dataminer OatmealDome looked into the new firmware, and discovered that for the Switch 1, the web browser was updated, alongside the controller-handling code, while the changes for the Switch 2's firmware are a bit more unclear. Currently, Nintendo's website only shows the update having released for those with Japanese consoles.

I honestly do not mind frequent updates.

I just downloaded the 20.4.0 firmware, It uses the existing keys so no new PickLock is needed.

Sigpatches and SYS-Patch Sysmodule are the same so current versions works fine.

Bootlogos are exactly the same set of patches so no need to rebuild new ones.

@JK_ 's PNGShot will work fine because no new patches are needed.

NXThemesInstaller do not need to download new set of patches.

So we need just to wait for new Atmosphère and Hekate for update.

No news on https://switchbrew.org/wiki/FirmwareNews about the 20.4.0 firmware so we do not know yet which changes are included.

What was the last update?

What was the last update?

20.3.0 - also a "stability" update.

 

[M7L7NK7]

"Web browser update"... If only we got an actually usable web browser in HorizonOS 21, but there's no way that's happening.

Why do you even need one, just use your phone

Wow! Another boring update!

Boring update for 2 old boring consoles.

Hekate the author does not fix it, he only added support for 20.4.0 to version 6.3.1

Version 20.4.0 sounds like a significant milestone. Can’t wait to see if there are hidden features or quality-of-life improvements waiting to be discovered.

Bla bla ai slop

If only they were useful and added new features.

can confirm update breaks atmosphere

hekate loaded after restart but upon trying to load atmosphere, switch had an infinite black screen

 

[Delerious]

Ya'll are just a bunch of nay-sayers who hate stable builds.

Being real, though, I wonder if they increased the Webcam frames from 15 to 20, yet.

yeah, do not tell me that.. AS POSTED SEVERAL TIMES BEFORE any FW will «break» Atmosphère is a safe measure of Atmosphère to avoid bans and damages.

@impeeza thats why my NS2 does not touch used NS game cards (the risk is low ik but still)

Does atmosphere work on this or do we need to wait for an update?

ALWAYS wait for atmosphere to either update or list the firmware as compatible

you can't possibly be so addicted to bing bing wahoo you just asked that
