I bought a n3dsLL from Japan and region changed it so I could navigate the menus. I installed a 128gb microSD card to store all of my homebrew downloads and ROMs. Due to a series of unfortunate events, the microSD card sustained significant physical damage and is no longer able to be read or recovered. I have a new SD card, but I have now got the problem of trying to reinstall all of the necessary files to run homebrew. I can't copy them over from the old sd card due to it being dead and I am afraid trying to factory reset will result in bricking. What should I do in this instance?
