He gets the error even on 8.0.that error is due to using luma 7.1 with b9s 1.2. they're not compatible.
Did you follow the "CTRNAND Luma3DS" steps? I wonder if you copy the boot.firm file and then turn off your 3DS. Turn on without the SD card and see if it works without the card.No it´s quite sucessfully, but i can´t boot anymore the 3ds.
