Once a Nintendo update bricked my console. Black screen of death after a brief moment of Nintendo logo. The console was on, the fan was spinning, but that's all.
It's a v1 console, and it booted into Hekate and CFW no problems. So after following a video on YT, I was able to reflash the whole device with the latest firmware.
It works now flawlessly, tho always a bit butt clentching when there's new update. I play online with it a lot on OFW, not even using the CFW for anything. (I have a chipped Lite for all my hacking desires.)
I contacted Nintendo what the fuck is this (prior I think I got shadowbanned in Animal Crossing as well since no online features worked in game), we had shared some emails and that's it. They just ghosted me.
So, if this is the case, people SHOULD hack their Switches, just to have a way to emergency restore their consoles.
Personally I wouldn't trust it even though so far there have been no problems playing online with official firmware on a modded console. It's possible they could detect it in theory and Nintendo does not take unauthorized use lightly, even if you purchased the game and Nintendo online subscription legitimately.
In the UK version, the digital product may become unusable, in the US version, the device may become unusable:
The agreement for UK accounts now states digital products are "licensed only for personal and non-commercial use", and that any "unauthorised use of a Digital Product may result in the Digital Product becoming unusable".
This differs slightly from the US, which states: "You acknowledge that if you fail to comply with the foregoing restrictions Nintendo may render the Nintendo Account Services and/or the applicable Nintendo device permanently unusable in whole or in part."
We can't help them folks. They're in a cult. It's the same madness that gets people to buy Apple again and again, perpetually locked into the same ecosystem.
Would be an awful shame if some hacker bricked every Switch in the world. Probably shouldn't be coding in a kill switch into consumer entertainment devices.
Whoops, I may have just given Nintendo a great idea to increase Switch 2 sales
