So I bought a new switch strictly for homebrew use in the future. I turned it on, went through initial setup without going online, checked the firmware which is version 4.1.0, and then I updated the attached joy-cons. I powered it off and put it back in the box until the day comes when CFW is ready for use. Again, I did not connect to any networks during the setup process. Afterwards, I wondered if updating the attached joy-cons may have been a mistake that would interfere with hacking it later. I don't think so but I'm curious if anyone knows for sure. Thoughts?
