You're o3DS so it might not be the same, but for those of us with N3DS that got this problem, formatting the 3DS itself (not the SD card) did the trick. I had well over a dozen soft-bricks, and when I formatted the 3DS it worked the first time.
I just realized this myself, about to do it now. I have some software saved to my SD card though, is my save data safe for when I put the SD card back in? I'll probably have to redownload the eShop titles right? (doing system format memory without the SD card in)
If you installed the update, but youre getting an error, reboot WITHOUT your sd card. Then insert your sd card if it boots up successfully.
I downgrade successfully, but kept getting a black screen. I took out the sd card, and everything worked
Tried this many times, still no luck. May have to go with the system format option.
