I want have a 3DS as originally was. I haven't NAND copy. How I could unistall B9S and have the 3DS with OFW? I tried this guide: But when I try the guide, in the step 3, GodMode9 say: "Failed copying path: firm0.firm (<A> to continue)". I am using: New 3DS 11.4, Boot9Strap 1.2, GodMode9 1.2.1 and Luma3DS 8.1 SOLVED: The problem was that the name wasn't correct. The name was "firm0.firm" when is must be "firm0.bin".
