so i have a 128 gb sd card with a 16gb version of android cfw on it, i already know how to set up dualboot with atmosphere and switch ofw, but i have no idea how to set it up with android and atmosphere and the official switch firmware for online,
The best way to get android, OFW and atmosphere at the same time without risking a ban is to set up both android and an emuMMC partition on your SD, then you can use the emuMMC partition with atmosphere and the regular eMMC with OFW. (For now it isn't possible to boot an emuMMC version of official firmware, it should be in the future.)
