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)
EDIT 2:
There are currently NO known ways of removing SUPERNAG. Anything you read is likely speculation and proven to not work already. Things that have been tested:

- Maintenance Mode
- Console Initialization (both through settings and maintenance mode)
- Failing an update due to battery/etc (don't even try this, dumb idea and not a chance of working)
- Fake news
- Puyo Puyo Tetris or other web browser entry points
- Updating via a cartridge (this COULD work, it depends on when your unit went online. If it went online before the FW on the cart was released, it *should* clear it. Considering supernag was added in 4.1.0, and there are no public exploits for >4.1.0 currently, this is useless)
