Every time I try to downgrade my o3ds xl to 9.2 following the Plailect Guide (via Cubic Ninja) I get the "An Error Has Occured" black screen and have to use recovery mode to restore. This happened to me once on 10.3 as well, but by that time 10.5 had come out and I got stuck unable to try again after restoring.
I went to the #3dshacks IRC channel and a few other people reported the same issue. It sounds like reformatting from system settings fixes it, but I really don't want to reformat and lose my mii plaza etc.
I get the black screen whether or not the SD card is inserted, and it happens even when I remove the SD card right after the downgrade completes before restarting.
The downgrade in SysUpdater itself always succeeds and I get to the "press B to restart" message. Then it boots to the black screen. My best guess is something in my sysnand is crashing 9.2 on boot; I've had a 3DS since 2011 and this XL is a system transfer from my old ambassador 3DS, so it's possible I have something unusual in my nand.
Any ideas for things I could try that might get downgrade to succeed? Is "keep trying" worth it?
Alternative idea: would it be possible to system transfer back to my other (old) 3ds' emunand (installed CFW just fine on it), reformat+downgrade my XL, then system transfer back to the XL running a9lh?
