I bought this card a few months ago and updated then and everything worked fine on my 3DS. A few weeks ago I updated the 3DS software first (4.5.0-10E). I tried to play on the DSTWO but it didn't work. Then found out there was a Firmware update (1.19) so I downloaded it and put it in the root of the SD card and changed the file to "dstwoupdateb.dat". Now my 3DS won't recognise the card, as in, the game card won't appear on my 3DS so I can't open it. I put it in a cousin's DSLite but it didn't show up. I thought it was bricked so I tried to unbrick it by doing the PART 2 method (http://forum.supercard.sc/thread-8384-1-3.html) but when I pressed the B button, nothing worked even after 15 min of leaving it after I pressed the button. I now can't use my cousin's DSLite as it was a once a year visit. So, is there a way I can fix this with just a 3DS and DSTWO card?
