you can run any cfw to use with ChoiDujourNX to update ;) Edit: Ive just seen your above posts use hekate payload to use ChoiDujourNX to update to 5.1 ;)
yes if you don't want to update your game cart slot! ;) I prefer autorcm anyway no more jig! ;) But most of the time I leave the switch in sleep mode hardly loses any charge! ;)
No it's not using this https://gbatemp.net/threads/choidujournx-a-system-firmware-installer-homebrew-for-the-nintendo-switch.513416/ it is all automated for you! Simples! ;)
