From what I've read there are successful attempts flashing (NDS?) r4i-sdhc firmware over the original R4i B9S, on a R4i B9S? I'm interested in the (almost) opposite, flashing B9S to a R4i 3DS WiFi RTS (stock firmware). Has that been done? Successfully? If not, should I attempt to flash a backup from a R4i B9S (like @pandavova posted) on my R4i 3DS WiFi RTS using an already modded O3DS and the ntrboot_flasher posted by @Kitlith in this thread previously?
