Happy June 15! @SciresM has released a new update for his Atmosphère Switch CFW, which is now able to boot on firmware 7.0.1 and 7.0.0 without the need for end-users to provide any keys.

For those out of the loop, initial 7.0.0 support was already added some time ago (31st of January) but it did not include a key derivation algorithm for said firmware, relying on a bring-your-own-keys (BYOK) approach instead. Said keys were private and only a few individuals had access to them, meaning the average user was not able to make use of this feature. Some time later a minor firmware revision was released, 7.0.1. The update contained very few changes and the TSEC was left untouched, meaning whatever key derivation algorithm was being made for the previous firmware would work painlessly on the newest one aswell.

Now, said algorithm is finally complete and has been included in the aforementioned release. The new approach relies on a payload called "sept" (which is french for "seven") which gets automatically executed by fusee-primary if the CFW detects it needs to get the 7.0.X keys from the TSEC. It only adds around a second to the total boot time without the need of any user interaction. It comes pre-signed on release builds, thus making it a full non-BYOK solution for regular users, however if you're a developer or power user who likes to compile unofficial builds directly from the source you will still need the appropriate keys to sign it.

The new release also comes with other improvements and changes, some of which were already pushed to the repository sometime ago (for example, the improved reboot to payload function). The full changelog is as follows:

0.8.4 is Atmosphère's tenth official release.

fusee-primary was last updated in: 0.8.4.

The following was changed since the last release:

• Support for 7.0.0/7.0.1 was added.
  • This is facilitated through a new payload, sept, which can be signed, encrypted, and then loaded by Nintendo's TSEC firmware.
  • sept will derive the keys needed to boot new firmware, and then load sept/payload.bin off the SD card and jump to it.
• Recognition of applications for override/mitm has been improved.
  • Nintendo's official Title ID range (0x0100000000000000-0x01FFFFFFFFFFFFFF) is now enforced.
• A deadlock condition was fixed involving libstratosphere mitm sysmodules.
• Kernel patches for JIT support were added (Thanks, @m4xw!).
  • These loosen restrictions on caller process in svcControlCodeMemory.
• set.mitm and fs.mitm were merged into a single ams_mitm sysmodule.
  • This saves a process ID, allowing users to run one additional process up to the 0x40 process limit.
• A bpc.mitm component was added, performing custom behavior on shutdown/reboot requests from am or applications.
  • Performing a reboot from the reboot menu now reboots to atmosphere. This can be configured via system_settings.ini.
  • Performing a shutdown from the reboot menu now works properly with AutoRCM, and does a real shutdown.
• General system stability improvements to enhance the user's experience.

This version can be downloaded from Atmosphère's releases page on its GitHub repository (link in the sources below).

Atmosphere rocking the Switch since 2018 and beyond...Oh wait...

 

[Creatable]

Wow, this makes me very excited for tomorrow's SX update!

 

[Ghassen-ga]

Coming next,

"SX OS support for 7.0 is released".

Oh well..

no

YES! SX OS to follow tomorrow!! (Or after tomorrow)!!

 

[SaffronXL]

Thank you for the clear explanation of what Sept is and how it works.

 

[huma_dawii]

@tomGER I guess you already know, but hey! SDFiles update today please <3

 

[DSpider]

So now we can perform a real shutdown from Horizon, without dropping automatically into AutoRCM (and then having to hold the power button down for 10 seconds)? Sweet!

 

[aos10]

now my friend can shut up about not able to run hacks on last update

Don't turn this thread into a sx vs atmo thread

it was already ruined by someone else

Coming next,

"you will still need the appropriate keys to sign it", will this affect TX somehow?

Assuming TX doesn't have their own trick of having TSEC decrypt the firmware or keys to hardcode into their CFW, they would have to incorporate sept which has an Atmosphere splash screen embedded.

Can you tell me how to boot hbmenu.nro with atmosphere? It launch the album app instead

ok, now I know you’re not reading my posts. goodbye troll

well I copied the hbmenu.nsp into the atmosphere folder but it does not boot hb menu

Couple of cool features here. The fact that they basically signed their own TSEC payload is hilarious to me and I actually really like it since it means that there's no exploits being burned to do this.

Secondly, that "limited mitm" range can serve to protect Homebrew from being layeredFSed (and therefore reduces idiots trying to layeredFS it) if you're using NSP homebrew (which things aside is a bad idea).

Reboot functionality is just awesome and I like that the shutdown/reboot thing got patched as an AutoRCM user.

Gratz on Scires!

You need to copy the file named HBL.NSP to the Atmosphere folder. Nothing else. HBL.NSP. That exact name.

 

[Purple_Shyguy]

The absolute madman is actually going to do it

1.0 will release June 15th
