I'm on the step where you restore emuNAND_original.bin to your sysNAND (with keep a9lh), and it seems to have frozen. It's just sitting on 0%. I tried to join the IRC channel mentioned in the walkthrough but I couldn't figure out the quiz and I'm like, freaking out too much to figure out how to google the answers right now (I know, I know). What do I do? Is it safe to shut my 3DS off? Should I just leave it on this screen?
