Just a while ago, I was trying to update my Luma CFW through the Luma updater to version 8.1 from 7.1. I opted for the stable version and disabled the option to download to CTR-NAND (or whatever it was called). My 3DS was able to reboot but my Luma version stayed the same (still 7.1) so I was wondering what the problem was. I went through the Luma updater again and it still said I was on 7.1 so I decided to opt for the stable version again but this time I enabled downloading to CTR-NAND. The updater said the update was successful and went to go reboot but this time my 3DS didn't turn back on. Every time I turn it on, the blue led goes on for a second and then turns back off. I tried taking my SD card off the 3ds and it does the same thing. I realized I made a serious mistake and I'm hoping I can get some help to circumvent this problem.
