So, I followed a guide on how to downgrade the N3DS XL, and it worked fine. However, once the downgrade finished, it rebooted with an "error has occurred" message. I restarted the console, and it simply would not boot to sysNAND, just a black screen. Upon taking out the microSD, the console successfully booted to sysNAND. I checked, and the console is on 9.2.0. I tried using the MicroSD again, no dice, it wouldn't go to sysNAND. So, I reformatted it. Now it works again with the SD. However, no homebrew will launch now. Every homebrew launched will result in a black screen, requiring a reboot. I've tried formatting the system, formatting the SD again, downloading fresh files, mostly everything I can think of. Any ideas? Cheers.
