You can remove the pending update if you enter maintenance mode.
To remove it from sysNAND / OFW:
- Make sure that your Internet connection is disabled if you're connected right now and remove any saved connections as well.
- Turn off your console (when in home menu, hold the power button for a few seconds and select power off).
- Hold volume + and volume - at the same time and, while holding them, press the power button. After a while your Switch will enter into the maintenance mode. At this point any pending update is deleted and cache is cleared.
- Press the power button once again. It'll shut down the console. The pending update should no longer be there.
On emuNAND, it's a bit different:
- Make sure that your Internet connection is disabled if you're connected right now and remove any saved connections as well (unless you have DNS MITM in place).
- Turn off your console (when in home menu, hold the power button for a few seconds and select power off).
- Right before you send your fusse.bin payload, hold volume + and volume - at the same time. Keep holding until you get into maintenance mode (you'll see Atmosphere bootlogo first, Switch logo after that one). After a while your Switch should enter into the maintenance mode. At this point any pending updates and cache is cleared, you don't need to press and/or select anything.
- Press the power button once again. It'll shut down the console.
- Boot into CFW the way you usually do and make sure to activate flight mode. (Connecting to the Internet is safe only if you have DNS MITM in place.)
- The pending update should no longer be there.
Since you probably didn't remove the pending update on OFW, it got carried over to emuNAND upon creation.
That's usually the case so always check if the Hekate and Atmosphere (and sigpatches, if you use game backups) support the version you're updating to before doing an update.
If it's
90DNS you're talking about, you need to set it up for each and every connection your have, either manually or automatically with this homebrew. However, DNS MITM is much better as you need to set it up only once.
You might have connected to another network? Disable automatic software updates in the system setting and set up
DNS MITM.
