I have followed Plailect's guide very closely (my knowledge of CFW is somewhat basic) from Part 4 on my n3DS (I already had AuReiNand 10.7 installed and working). Every step has worked perfectly up to this point and I had no issues obtaining my otp.bin. I am currently stuck on this section where it says: Launch SafeA9LHInstaller The installer will now install arm9loaderhax on your device (this is very fast) Your 3DS should reboot into the AuReiNand menu. If you get a black screen, follow this troubleshooting guide. I didn't get any errors with SafeA9LHInstaller, but the device did not reboot as expected. I am greeted with a black screen on manual boot. I followed the troubleshooting guide and booted with the test payload which allowed me to shut down with the A button, proving my device is not bricked, "arm9loaderhax is working and something else is broken". I was able to restore to my sysNAND_original.bin backup through Decrypt9 to try Part 5 from the top, but I end up with the same issue (black screen). Any idea what could be causing this? EDIT: The issue is resolved. I'm an idiot. my AuReiNand settings were not properly configured and it was trying to launch my emuNAND 2.1. Thank you everyone for your help.
