You read it right. I have the OG Switch (HAC-001) and the newest update broke it. It does not get past the Nintendo logo.
I haven’t hacked my Switch.
It got bricked right after restarting.
Other people have updated and their Switch is somehow fine.
Help…
Yeah, Atmosphere might be a way forward if you wanted to go that direction. (Assuming a) the issue is an efuse issue and b) you have the right version of the Switch. You can check if you do by checking your serial number against the list here.)
Only other suggestion I’d have is to get in touch with Nintendo.
