I wanted to post this in the FAQs section, but it is only for tutorials. Forgive me if I post in the wrong section. Alright, I have followed this guide https://gbatemp.net/threads/tutorial-installing-rxtools-custom-firmware-3ds-and-2ds.390867/ in order to install homebrew and rxTools (the latest build of 2nd of February), but something has gone wrong. Well, if I update emuNAND, after preparing the Home menu the console freezes in a black screen, and nothing seems to work (with the exception of the power button, from which I can turn off the console or make it freeze in the "HOME" screen -the same that occurs when you quit from the browser). I've tried to boot it 4-5 times through browser and 2-3 times from Homebrew, and I still get that black screen. https://mega.nz/#!rQcCDZAY!_AeQMfQ2WrUxy8NEL6g30Bd7D0bq1x20h_zgfVr4XLY This is a video of what I have currently, it explains perfectly what I'm saying (there are some references to the creator of that guide about the new rxTools build, but that shouldn't be a big deal). Hope someone can help me. P.s.: I have done the process 3 times (by formatting and restoring the original partition of my SD card every time), and lost every data on my sysNAND in one of my attempts. However I continued the guide and finally got my emuNAND update correctly, but without my stuff. In order to restore it, I was suggested to inject my NAND.bin into emuNAND, delete the Nintendo 3DS folder and to copy a backup of the same original folder in my SD; in the end, I re-obtained everything back. BUT, I wasn't then able to update, and got once more the black screen. Seems like a problem of my NAND.bin, but... I've dumped that correctly and without issues, so I don't know which kind of problem the NAND.bin could have -or my console. I really don't know.
