While i agree with the statement that the only solution is modchip for the time being.
There is in fact exploits that are not public, and they will probably never be released.
Why burn these exploits before you know if they work on new hardware.
It’s like in the PS4/PS5 scene, there is
”jailbreaks” for most of the firmwares, just not public.
With that said, a pure software based hack will not be released before the new switch and before the old switch reaches EOL.
Even then it might not happen, we are talking years from now. So dont get your hopes up.
If you want to mod your switch, use a modchip today.
