Was installing arm9loaderhax on my boyfriend's 2DS. Everything was going smoothly up until it was time to restore my 9.2 sysNAND.bin. I was repeatedly told by the software that both it and the emuNAND.bin were invalid. "No big deal" I thought as I popped in my Theaterhythm cartridge to update to 7.1. Now nothing works. Can't get into settings, can't open web browser, I can't even launch a cartridge so updating with another cart is a no go. Even recovery mode won't load. Is there anything I can do? Why did this happen?
