Those original consoles are becoming more rare, you could have probably sold it for close to what you originally paid for it, exactly because of that older SoC!
SoC has a bootloader exploit which makes it great for homebrew.
As far as I know, not every original SOC switch has this exploit, just ones from the first year of production or so. There are tools to lookup your serial number and see if you have a valid model. My switch has the homebrew exploit, but none of my friends' switches do, and they're all the first switch model but mine was purchased a few months earlier than the others.
It has an unpatchable hardware exploit that allows it to run unsigned stuff, IIRC.
Cool, maybe I’ll keep my old one then. I bought it at release
