Hacking How to block Software update and System Firmware update messages?

[wurstpistole]

Hi,
so for the past few years I've been using incognito on my Switch, that is banned anyway. Never got any message to update a game, or that a new firmware update was downloaded.
When updating to 17.0.0, I removed incognito since it caused crashes.
Now I get prompts when I try starting games, that there is a new update available. I can't download it of course, because I am banned, but it still shows.
Also, yesterday, I got the message that a new firmware update was available (17.0.1), and by looking at system settings, it indeed said downloaded and ready to install.
I don't want that. I set up DNS MITM to block Nintendo servers, but the update messages still came. What do I need to block to prevent this from happening in the future?
Despite being banned, it apparently still pulls information on new software and firmware updates.
Thanks.

Once the update nag is loaded, it is stored and doesn't disappear.
Have you tried going into maintenance mode (power & vol+ & vol-, NOT RCM) first to clear all pending nags? In maintenance mode, you don't need to press any buttons because just booting into it deletes the nags.

I know how to remove it, I want to prevent it.
Seemingly, blocking Nintendo's servers via DNS MITM isn't enough.

127.0.0.1 receive-%.dg.srv.nintendo.net receive-%.er.srv.nintendo.net


Try using these. Should block even the updates

Thanks, will include those.

Although they should have been included already, since the whole domain "nintendo.net" is blocked already.

Hmm strange, that should have blocked the updates for games if they haven't included a new url.

For as long as I was using incognito, I never had any software or firmware update nag. Now that the serial is restored, it seems to be able to connect at least partly

It will nag you since you are not blanking out your serial number, if you use sysnand cfw and boot into stock then back into sysnand cfw it will nag you.

With Nintendo servers blocked through dns mitm, I could blank the serial again, right? Since it shouldn't crash then due to not being able to connect in the first place.

Yes you can blank out the serial number again.
