Step Out IV makes you able to boot 3ds without sd card. If you always have the sd inside, you can skip it.As too many postings came after my question i will just ask again before i do something wrong:
Do i really have to do "Step IV - CTRNAND Luma3DS" from plailects guide (https://3ds.guide/updating-to-boot9strap) ?
I only use Gateway Emunand, standard boot is Luma3DS to GW Emunand and everything seems to work fine after i finished step III.
For what is Step IV useful ? Should i do it or don´t do it ? If i should do it, please tell me why it is needed, as i really do not understand
Thanks everyone
