Sorry for the long post and for the bad english, I'm just kind of panicked. And sorry if I'm making this thread on the wrong place or with the wrong title. My 3DS was at the 11.2.0-35U version, and it runs by emunand9 (don't know it that's the exactly name, I've hacked it in march 2016 and use aurei and the Ocarina of Time entrypoint). It is in autoboot and with uncart and aurei/homebrew before the system starts if I press R, L or L+B. I'm giving that information to see if I can explain better my homebrew and how my emunand is working. I've lost my HD data and lost my sysnand/emunand backups with it, so using backups isn't an option. When I got the 11.3.0–36U tomorrow, when my 3DS restarted, it just get in a black screen and then both screens turns off. They're not in black screens, they're literally off. The blue light in the 3DS remains on and I have to turn it off holding the power button. But if I start with the aurei or emunand, it gives a "no aurei found"/"no emunand found", and uncart is working just fine, I managed to start to create a Pokémon Y CIA. And, finally, if I turn on my 3DS without the SD card it just shut down, blue light and all. I can post some images of the 3DS screen in uncart or aurei/emunand messages, or even a print of the SD content. And don't care about saves or having to redo all the process of the hacking or returning it to the sysnand, I just want my 3DS to work.
