Hi there. Running A9LH on an N3DS running .corbenik\Luma Been getting 022-2634 for quite some time and I thought I'd try to restore it. After some searching in the forums I think I found the answer, but I am unclear on a few steps so I thought I ask first. Do I backup my NAND first? If so, what program do I use (I have chainloader Emunand9 if that helps)? Afterward, I understand that I need to format, but do I use system format or Tinyformat? Also, do I take the SD card out or not? Lastly, would I then use a program like Emunand9 to restore the NAND if I needed a backup? Thanks ahead of time.
