Alula's Atmosphere 1.11.0 FW 22.0.0

[LuigiGad]

I bought a Switch to install Atmosphere. I want to know about the possible compatibility with version 22, to provide a reference for whether I should keep the Switch (thank you very much to your team for your selfless efforts, I am just a bit anxious, games are too expensive now, buying the Switch already cost a lot, my daughter and I are both very excited). Thank you again for your efforts.

Yes, you can easily create an emummc 22.0.0 and downgrade it to 21.2.0. The process is different than usual, but it can be done easily.

I searched on the Internet and found that the Switch has a fuse mechanism, and once upgraded, it cannot be downgraded. The emuMMC you mentioned, can it downgrade from 22 to 21? I am a beginner, so I would appreciate it if you could give me detailed information.

Well first, do you try going into recovery mode? (Power/ Vol+/Vol- together). You can update the firmware again from that. There's lots of youtube videos on going into recovery mode.

If that fails boot into CFW with current AtmosphereNX to your sysnand (this ignores fuse count), you can then update your sysnand with daybreak to 22.x.x again and it will boot normaly without cfw.

Before you start messing about, dump your sysnand with hekate and store it somewhere safe.

hexkyz has provided us with an update on the current development:

Development update:
Progress is currently focused on restoring homebrew compatibility. A change in how AM manages the applet/application ecosystem created a problem for hbmenu and libnx. Closing down service handles or domains (specifically for ILibraryAppletProxy or IApplicationProxy) now triggers a cleanup operation which in turn signals an event that qlaunch is waiting on (which is problematic due to the homebrew ecosystem diverting from the expected way to exit).
Reasearching the issue and figuring out a good enough solution is currently the top priority.

It's nice to hear that things are moving forward. Many thanks to all the developers who are investing their time and effort in this project.

I wonder if this has to do with this for homebrew not working on 22.0.0

I think it may be related to what N patched in 22.0.0

Changes in and surrounding page table logic:

• KPageTableBase::LockForMapDeviceAddressSpace now checks for a new KPageTableBase boolean, m_allowed_exec_device_mapping, and decides between KMemoryPermission_None and KMemoryPermission_UserExecute for the permission mask value if the boolean is, respectively, set or not.
  - This prevents mapping any executable memory as device memory.

Though I don't think this will give you any chance at running CFW.

If I understand this correctly, It allowed getting new mapping to...

• masagrator

I didn't read anything about the instant crash when starting FW22, but this prevents it.

Are we there yet ?

Are we there yet ?

I would suggest against updating to the latest Atmosphere build until devs release a stable and working version. So no, we're not there yet but getting there. Be patient.

Mortal Kombat 11 gave me an error on my 21.2.0 switch today.
"An update is required for online features"
I was still able to play online up until today.

Then get the update and install manually

if anyone is online.... you have to get FW update. The games are forcing FW updates to use online features now.

Fucking Nintendo is enforcing firmware updates now.


if you are offline or banned.... you do not need to update to 22

 

[phillyrider807]

Yup FW 22 is being forced now so anyone who has yet to update you either have to now or stay offline for the time being.

I bit and updated cause of the Home update. It is what it is. Patiently waiting for the new Atmoshpere!

Just downgrade to 21.2.0 on emuMMC for the moment is the best solution

I use my switch online. But yes my emummc is fine.

I accidentally updated my system, and I use cfw with sysmmc for modded smash online. Is this unofficial fw22 repo here not safe to use, or not safe to use online?

the poster of this fork said it would not work online he intentionaly patched it that way to prevent people from getting themselves banned if you are patient the official version is being worked on and should hopefully be done soon

Thank you, appreciate the clarity. I read through the whole thread, but must have missed that.

I know you all are impatient, but please either build it yourself (instead of using builds with dubious patches) or just wait, 1.11.0 will be probably tagged later today.

 

[ELY_M]

@alula is right. I only trust the official repo and alula's repo and I built it myself. I had to update because Nintendo is forcing to update to use online features.....
