Hi, i decided do try installing a cfw on my 3ds and it was going well until i managed to fuck it up. Was following this tutorial https://github.com/Plailect/Guide/wiki/Part-5-(arm9loaderhax-&-AuReiNAND) and managed to get to installing de cfw itself, downgraded and all fine, but somehow i managed to mess it. So i got to the Configuring AuReiNAND, but since i was doing fast like a moron i only checked the first option and did not see that i needed to put all 3, then i went to reboot do get do decrypt9 and got a error saying firmware90.bin didn't exist, and to press any button to shut it off. Unfortunately i don't know if it had/has anything with the fact that i didn't check the 3 options prior to this, then i tried to run the same steps again to correct and see if i could get the other 2 options but it only gives me black screen. I tried launching OTP to restore the sysnand and emunand to the step IV on the tutorial, but OTP also doesn't work now, tried from the homebrew and from the browser too and nothing. So i am stuck at this point, don't really have the knowledge since this is the first time i am doing this, does anyone have an idea what should i do, i feel the it must be something really simple but i don't know what. Appreciate.
