I guess someone in the Homebrew community collected our 3DS data.
I had my 3ds flashed with Luma3ds and all the stuff needed. The only App i used frequently was ****shop (i know piracy is bad).
i never used my NNID somewhere else only on the 3DS.
edit: i also want to say that i havent used my...
latest version of Rufus with the recommended settings. i tried some different settings too. i doubt that it might be my usb since i used the usb for severel other USB OS stuff
ye it is. i even removed windows from the boot order so the only thing in my boot order was the usb. on the system i wanted to test the usb it went straight to bios again.
