That is, if I create a wi-fi network without an internet connection with redirect all sites to a local pegascape server everything will be fine?

Thanks for your thread, I had to clear a normal nag for 8.0.0 in maintenance mode... so I guess I can stop waiting for a hack compatibility :yayswitch: .

Alternatively, you can do the following in order:
  1. Select your Wi-Fi network
  2. Put in an incorrect password
  3. Save the settings
  4. Enter the settings
  5. Put in the 90DNS settings
  6. Put in the correct password
  7. Save the settings
  8. Connect

I was so happy, that deja vu is finally out and I though that maybe one day I will be able to exploit my little 7.0.1 patched unit. Now, after I found out that my unit is sick with "supernag", I feel like there is 0% that It will ever be hacked. Probably will just buy one unpatched from US with extra 70$ for shipping to europe and tax. Really sad day for me.

What is the best method to get an unpatched one?

Umm, there is a rumor, that if I tried update switch with 10 percent of battery, update will fail, and nag will dissappear.. anyone can confirm this? Or it is just for normal nag?

I know about this method, just wanted to make sure that just do not need to allow connect Switch to the nintendo servers and I want make portable wi-fi network (on esp8266 or something else) for excluding supernag and moments when I not home or without internet

If you use a Wi-Fi network without an internet connection, you won't trigger the supernag.

This was/is a major issue in releasing the deja vu chain and nvhax in particular. I was hoping to do a more compact release once I had the time, but since emummc was a priority, we released the nvcore code (implementation of nvhax) some time ago on Discord for others to research.

Be very careful with anything that requires using the browser on a patched Switch. This includes regular PegaSwitch (even plain browserhax which was fixed to work on 4.1.0 recently) and the PegaScape project (PegaSwitch front-end). If your console manages to connect to official servers and the "needs_update_vulnerability_policy" setting is changed, your console will never be able to access the browser again ("supernag"). The vulnerability policy setting is saved in NAND and can't be cleared even with a factory reset.
It's still unclear if it's possible to trick the system into reverting the status of "needs_update_vulnerability_policy", so it's best to avoid it at all costs.

On the other hand, if you manage to boot into CFW on a patched unit using the deja vu chain (now available via the Caffeine and PegaScape projects), make sure to dump your NAND right away. If you have a NAND backup and your patched unit's BIS keys, even if you mess up in the future (and activate the "supernag" somehow), you'll still be able to flash that backup externally (requires additional hardware).

I've been waiting for a while, this is really some sad news for everyone that has gotten the supernag. Nonetheless there are still a couple of things that I haven't found clear answers on:
1. What about updating from cartridge to 1 version above the current version? Is there a list of cartridges that come with said updates?

2. From a reddit user, according to SciresM, Puyo Puyo Teris JPN might be able to bypass the Supernag, is this confirmed?

3. Removing the update files so the switch has to download them again, and then start actually updating the switch within Recovery mode however when it is still downloading the update files in the screen "Downloading update data...." actually turning off the switch by holding the power button. Maybe since it starts the process of updating, the variable gets changed? Before anyone tests this I hope there is some safe way of finding this out, don't want anyone's switch to brick because they turned it off in the update process and a (slow) internet connection might be required.

There is currently no confirmed way of removing the supernag without restoring an old NAND backup using a hardware mod. The methods you've outlined, and others, are still being investigated.

While as of the last couple days thanks to tremendous effort from people in the community such as SciresM, hexkyz, and deer/liuervehc, we now have patched Switches on 4.1.0 Firmware running Atmosphere/emuMMC on 8.1.0. Unfortunately, some further requirements were not made exactly clear previously until individuals were unable to use the Deja Vu exploit chain on patched Switches. This is caused due to what people call "supernag", Supernag occurs when your Switch connects to Nintendo servers and writes save data indicating a new firmware update is available. When this savedata indicates a version greater than your current version is available, your Switch will refuse to launch any sort of web browser which is required to launch PegaSwitch and the Deja Vu exploit chain. This savedata is persistent through any attempts to remove it on OFW, including system initialization, etc. The only way to regain access to web browsers on the Switch is by updating your Switch to a version greater than or equal to the version cached in the save data from when you last went online. If you last went online before 8.0.0 came out, you could theoretically use a cartridge to update to 7.0.1 once Deja Vu is usable on that firmware, but that could be quite some time before that is possible. I have tested virtually every viable method of removing supernag on a console, including updating with a cartridge, using Fake News/Puyo Puyo Tetris, and system initialization, and none of them worked for me. The one way I was able to end it was by updating to latest firmware with ChoiDujourNX (my example savedata signaled 8.1.0 update available, I will try to get savedata representing 5.0.0 and update with cartridge later to be thorough).

TL;DR: If you have a patched switch, NEVER LET IT CONNECT TO THE INTERNET. The only time when it should ever try to connect to the internet is if you have BOTH primary and secondary DNS set to a 90dns or PegaSwitch enabled server, and after ensuring neither your router nor ISP will redirect DNS requests. If your Switch attempts to connect to Nintendo servers, it is highly unlikely you'll ever have hacks on a patched unit.

Edit: Maintenance mode *will not* clear supernag. It can clear normal nag which just asks you to update (the prompt has 3 buttons on it), but supernag (prompt has 2 buttons) will persist as it is signaled by a system save that is not cleared from maintenance mode or system initialization (maintenance mode will only delete update data)
So, a browserless entrypoint, such as some kind of exploit with the album applet, would be the only say for these switches (including my own) to get CFW?

--------------------- MERGED ---------------------------

There is currently no confirmed way of removing the supernag without restoring an old NAND backup using a hardware mod. The methods you've outlined, and others, are still being investigated.
I was that reddit user, Connor on the RS discord later prove that Scires' hypothesis was, unfortunately, incorrect.

It has, however, been confirmed that, if your switch hasnt connected since 7.0.1 was the most recent update, you can cart update to 7.0.1 and it will denag. *THIS IS THE ONLY KNOWN METHOD FOR DENAGGING A SWITCH WITHOUT UPDATING TO 8.1.0. ALL OTHER METHODS HAVE BEEN TESTED AND THEY ALL FAILED.*

So wait I can cart update to 5.x (mine wasn't online after anything newer was out) and remove nag then I just need to wait for the updated exploit?
