    Somewhere in the steps in order to get OTP for my old 3DS, I must've done something that could lead to exploits- or it could be just the exploit doing its work. Yesterday, After retrieving it, I restored emuNAND and sysNAND. After that, I tried to delete all of the files on the SD card (to restore from the backup). For some reason, the Nintendo 3DS folder wouldn't delete. I went to go check it out. I found a file next to one of the random numbered folders that just said (and I can't recall EXACTLY what it said): "sdmc://bo.ot". I couldn't delete it. I kept getting errors and I couldn't open it without errors. I could MOVE the Nintendo 3DS folder but I couldn't delete it or the sdmc://bo.ot. I got rid of it by formatting. Everything's back to normal and I have A9LH installed but I keep thinking that I somehow found a bug in 2.1 that could lead to something

    Sounds like one of the tools got confused about how to make a filename and created one that has reserved characters in it; the homebrew fs drivers don't have a ton of validation.

    Sometimes you can get rid of those using the native api name at the command line, like del "\\?\S:\Nintendo 3DS\path\to\sdmc://bo.ot"

    Yeah, but afaik, OTPHelper or the OTP dumper that bilis did for 2xrsa doesn't create any files.
