Hacking Atmosphere-NX - Custom Firmware in development by SciresM

[GenoCL]

Anyone else getting an error code 2137-7404 when updating the FW after Atmosphere?
I'm sure it's not a DNS thing because I've used my Switch on CFW-Sys for YEARS updating there and this is the first time something like this happens out of nowhere.

I have two questions about this statement.

1. How exactly can he make sure no AI touches atmosphere when it is open source and under GPLv2?
2. Is he still reviewing code even after retirement?

Even if hexkyz is the official maintainer, I assume things would still be reported to SciresM so he can ask the former to take them down.

He did say "high certainty of being llm-slop", so I guess if someone gets it through, he might not notice. He is definitely anti-AI.

Nope. Able to use it on my sysMMC with no issue.

Weird, can't think of a reason as to why is this happening. I've always updated my Switch on CFWSys to avoid having to deal with a jig and for years it's has just worked until now.
Connection test is successful.

It could be your hosts file or a few other reasons, it's something blocking nintendo servers though. Just download the update from elsewhere and install with daybreak. (it's not hard to find with google).

Eh I guess I'll just update on Stock. Luckily I have a Hori Split Pad that surprisingly also works as a jig.
But I'm really puzzled as to why this is happening NOW after years of updating on CFW-Sys just fine.

Edit: Alright, I updated on Stock and now went back to CFW-Sys. Everything is fine aside from the "failed to apply nosigchk" so now we wait for SigPatches.
I'm browsing the eShop just fine so now I'm even more puzzled about the previous error. Somehow my Switch just decided not to download the latest firmware patch, I was wondering why I wasn't getting the nag message all this time.

Is it safe to play legit games on CFW-Sys with non-updated sigpatches?

I fucking hate AI!!!!!! I agree with @SciresM about AI stuff.

I'm using firmware 20.0 and it's a great satisfaction to know that the project is back and, apparently, stronger than ever.

Back to business, thanks a lot: Hexkyz / Alula / CTCaer, and all Others, I now have access to the eMuMMC again. I'll be more careful next time I update; I'll read more and investigate more. It happened because I was playing Fortnite; it asked me to update the system, and I thought it was just the game. But it's very satisfying to know that there are people like you, a true hero, that we're not helpless. Thank you so much.

I'm still on 21.2.0

Is it worth upgrading to 22.0 ? Any significant improvements like battery life, .... ?

Depends, how much does the nag annoy you? Do you need to go online with specific games and apps like the eshop or youtube?

None of them

I only use it for games and retro emulators.

Then you're fine.

recently updated to latest Hekate, AMS 1.10.2, HOS 20.5.0. I can't seem to launch anything with romfs enabled. Even a simple test file that does nothing generates a std::abort (0xFFE) error and forces a reboot. What am I missing here? Already ran the archive bit clear from Hekate.


Update: Should anyone else find this it appears to have been connected to a sysmodule but I can't say which one. I started over with clean Atmosphere which worked so I began adding them in one by one and everything kept working normally.

Good afternoon everyone, DBI in MTP mode is not establishing a connection after the Atmosphere update.

MTP - USB

I have a connection to the PC on Hekate, but there is no connection when dbi is active.

Issue not on switch side. DBI checks USB, got it initialized and started responder as designed. Check device manager on PC.

DBI works fine even in MTP and backend.

Thank you for your help, I did as instructed and it worked, may God bless you...

Damn.
And I just redid my full setup at FW 22 yesterday. Good timing, I guess.

Astounding, right after we got Atmosphere for 22.0.0. At least it seems to be a quick fix according to Alura, and we just need to wait for hexkyz to build it.
