You can follow
this guide. I suggest making an emuNAND if you have SD card bigger than 64GB.
If your stock firmware is the latest one, i.e. 17.0.0, once you make your emuNAND, it'll be on 17.0.0 as well. I suggest that you downgrade it to 16.1.0 via Daybreak. You can find firmware files on a certain website we aren't allowed to link to (it's really easy to find it, really).
If your stock firmware is not the latest one, i.e. 16.1.0 or lower, just make an emuNAND and update via Daybreak to 16.1.0 (of course, it's not necesarry to do so if it's already on 16.1.0).
Once you do that, make sure that you have the latest Hekate (
v6.0.7) and Atmosphere (
v1.6.1, it's the pre-release version). You should have them if you've followed the guide mentioned above. You can find the Sigpatches
here (these are for firmware 16.1.0 and Atmosphere 1.6.1).
Sigpatches for 17.0.0 are yet to be released, you'll find them
here once available. There are no games yet that require firmware 17.0.0, so there's no need to update to that one unless you've already done that.
