A new Nintendo Switch firmware update is available to download. System software version 20.1.5 has been pushed out to systems, and you'll never believe what's in the patch notes. This new firmware adds--you guessed it--general system stability improvements to enhance the user's experience. For now, it's not exactly certain what this update really changed under the hood, so keep an eye on the usual sources before you update your Nintendo Switch.

Ver. 20.1.5 (Released June 18, 2025)​

General system stability improvements to enhance the user's experience.

Just checked my Switch 2 and it's on 20.1.1 thanks to the DNS Blocker. Although, it's probably safer to be in Airplane Mode.

Master key revisions are only in major firms ie, 18.x.x, 19.x.x, 20.x.x // is fine.

6.2.0, 8.1.0, 9.1.0, 12.1.0

Tested on S2:

• currently it's just a facultative update
• E-Shop and online games still work on 20.1.1.
• without DNS Blocker set up there will be a nagging window
• deletable in Recovery Mode as usual

You're saying it's deletable via Restore Settings?



I'd like to update my Switch 1 cartridges, but I dunno now as I've never done that.

No need to touch Restore Settings. Downloaded (but not installed yet) updates are deleted automatically by powering the console off in Recovery Mode.

Switch 1 be getting firmware updates like crazy, burning through e-fuses like it's launch time all over again.

I kinda doubt that 20.1.1 -> 20.1.5 would be an eFuse version, but with Nintendo you never know.

Wow that's great news, thanks.

6.2.0, 8.1.0, 9.1.0, 12.1.0

you are right, thankfully this time 20.0.0, 20.0.1, 20.1.1, and 20.1.5 share the same keys.

I do get that they want system parity, so the frequent updates make sense. Makes me wonder how long they'll support both systems.

[Jayro]

can banned switch 2 update fw?

Probably only with cartridge versions.

 

[Marc_LFD]

Probably only with cartridge versions.

Yes, since it's banned from Nintendo services.

Switch 1 banned can download firmware updates.

 

[DbGt]

Switch 1 banned can download firmware updates.

Yeah, I know, thats why i was wondering if any banned switch 2 owner have tried to do a system update. I would guess its the same as with switch 1, so probably its possible

 

[Jayro]

Switch 1 banned can download firmware updates.

How? Mine errors out.
