@kat @EeveeEuphoria to hack a switch you need to put it into recovery mode by booting while holding volume up and home, like you do with a mobile phone

however there is not actually a home button on the switch itself

to achieve the same effect you have to ground pin ten on the right joycon rail. folks have built little plastic gadgets to do this reliably, which are called jigs, or you can use a paperclip or some other small piece of metal instead
