So I have this R4i Platinum card from http://r4iplat.com/. I was updating the card's firmware with the 1.43 update on their site ("fwupdate_for_143_drive.rar") and my DS froze right in the middle of it. Now when I turn on my DS it's not recognizing that my flash card is inserted at all (was working perfectly just before this). It just brings me to the DS menu as if there's no cart inserted at all. The sd card seems fine as I can still access the things on it from my computer. I've tried deleting everything on the card and reinstalling the previous firmware, but it's still not recognized. Is there anything I can do or is it gone forever?
