Hacking Atmosphere-NX - Custom Firmware in development by SciresM

[impeeza]

Does it work with the latest release of Hetake & Nix (hekate v6.3.1 & Nyx v1.7.0) or does it also require a custom built version of them?

IS EXACTLY THE SAME Atmosphère officially released. only have a extra commit.

Yes it works fine.

This is the commit d8a37b4b7 from the official repo build with latest libraries, I am attaching the Fusee.bin and sigpatches for this build.

installed it OK, then updated to 20.1.5 (daybreak) and upon reboot, got the following error on boot. Any idea what this might mean?

As the error told you, remove the SDMC:/atmosphere/contents/010000000000bd00 folder and if you use it, upgrade Mission Control

thanks! hadn't had a go at upgrading with Hetake, atmosphere and sysmodules quite a while ; I'm a little rusty! thanks for the quick reply and your guide! Indeed all fixed and running 20.1.5 fine.

Do I need to combine commit's atmosphere to the official repo atmosphere? Or delete the official repo atmosphere entirely and just use commit's version?
Can I just use sys-patches1.5.6 instead of sigpatches?

yes

 

[Krazyeye]

yes

Great.

Or delete all users and create new ones. But you have to backup all your saves and restore them to the new users

I have tried this. Deleting linked users in emuNAND is not straightforward, because it needs to contact N servers. Some homebrew (e.g. DBI) can force delete these users without phoning home, but it doesn't seem to avoid the issue.

For reference: unpatched Erista, 19.0.1 emuNAND, single user, with legit NNID. Update to 20.1.5 resulted in 80% battery drain overnight, unless Airplane Mode is on.

So I created a new user without NNID in emuNAND, then used DBI to remove the old linked user. Now that emuNAND has a single, unlinked, user. It still drains 80% battery overnight.

I guess the only valid solution now is to boot sysNAND and either remove the linked user, or update and accept the new EULA. Then, create a new emuNAND.

Did anyone try downgrading firmware via Daybreak yet while on the latest firmware to e.g. 18.x.x or 19.x.x?

 

[duckbill007]

Of course.

 

[Blythe93]

Of course.

Thanks, good to know! I remember reading somwhere that people weren't able to downgrade without issues from 20.x.x to lower firmware.

Well, he hasn't said that there is not any issue...

You can do it but after that you must to format the EmuNAND, because the User partition become invalid. Was a change on FW 20.x.x on the User Partition which is no retro compatible.
