I install CIA (ntrboot,luma,homebrew, I dont know) with R4 Gold Pro 2019, then when i got ''restore file not found'' i passed that section and removed my r4 card and play on my sd card. I sent r4 card to my friend but when he plugged r4 on his 3ds he cant saw r4 card, actually he can but only white, he didn't install ntrboot or anything btw that's why we cant do section V. I cant help him with my cfw 3ds because of the road and he didn't want to install ntrboot, So is there way to restore r4 card without ntrboot?
