ok so i have a switch i bought before june 2018. i bought xecuter sx pro and os. ive put like 10 games on there and everything is grand. now more games are coming out i want. so how do i update the firmware from 5.1.0, also is there a cfw that doesn't require the dongle. how do i install nsp games. so is there a guide that has this in there. i don't want to fry my switch. thanks.
