So I have been trying to setup A9LH, and I'm on the part where I injected 2.1 unbricked (N3DS) into my SysNAND, but I closed my 3DS on the 2.1 browser screen while I went to go take a shower (~20 min) and the screen was black when I came back. Now whenever I start up my system, I get "an error has occurred, please turn off the power" immediately as I boot. No luck trying to get into recovery mode, hangs at a black screen, screen turns on, but is pitch black. I've tried removing my SD when booting, but no luck there either. Is this recoverable or is a hardmod needed to restore a nand backup?
