I did it with cubic ninja and downgrade with the sysupdater. Now the screen is blackIt's probably not since you don't have a backup, but I think it also depends on what errored out when you were downgrading.
If it is recoverable, you'll need a hardmod.

Is there a tutorial to go to recovery mode
It actually takes a few tries to get into recovery. Well, worse case worse, you can either get a hard mod, or buy a new 3DS XL motherboard for around 50 something dollars.the screen is still black and I tried holding L,R, A and D pad (up).
