Recently I bought a DSTWO Plus from a second-hand dealer, and it's in pretty good condition. However, when pluged into my New 3DS LL with B9S and 11.13.0 firmware, it wasn't recognized. I used R4 card before, and everything functions normally. I borrowed my friend's NDS to see if there's something wrong with the DSTWO+, and it functioned normally as well. But somehow I can't get the 3DS to recognize and boot up the DSTWO card. Has anybody ever used this type of flash card on 11.13.0? I'm open for any suggestion or thoughts right now....
