I'm talking about after installing atmosphere, and turning the Switch off.
Is there a way to make my CFW load when I turn it on without relying on the Jig?
Use autorcm if you dont want to use a jig, but you still need a way to push a payload, like from a computer, phone, payload dongle etc. If you want to boot into CFW from power off state, then get a modchip fitted into the unit, and use autoRCM and autoboot, so it boots directly into CFW for you.
