Okay, so I've CFWd 2 3DSes absolutely fine now, no issues whatsoever. Trying to CFW my friend's, and it all goes smoothly up until the very last part where I'm trying to inject FBI into hs.app. Dumping works. Copying to PC works. Running the go.bat file works (I think?). FBI.cia is in the input folder, alongside the hs.app that was dumped. Whatever happens, when I inject the FBI_inject_with_banner.app (which according to Hourglass9 supposedly works and is "successful"), when I reboot the 3DS to go to Health & Safety, it's just the normal Health & Safety app. Opening it just opens Health & Safety. I think I'm going mad. Would love some responses to help fix this. Thanks.
