I tried hacking my sister's 3DS because she asked me to. Using this guide (http://extranullbyte.com/11-2-cfw-for-o3ds-and-n3ds-no-hardmod/) I made an awful mistake by rushing and did not back up the version. When I had to restore, (step 8) it gave me an error so I followed the linked tutorial. I tried to inject the FBI with that but didn't work and broke the H&S software. I went to update the system as instruced but it gave me an error. Now I can't update, and my sister, who is 9, can't play Yo-Kai Watch 2 without the update and I feel awful. How can I get the 11.2.0 version back? Is there a way via the internet where I can install through the SD card?
