Immortal_no1 said:i've also had issues updating mine, same process.
Had a Miami Nights 3D card, updated it to 1.4.2C i got the spongebob icon and get a blackscreen followed by needing to restart my 3ds, and on my dslite i get a white screen. i had the latest wood firmware on it too.
Contacted the guys at r4ids.cn they're looking into it now. i want to try updating my cards with a DSI maybe that will solve my problem, i'll try it tomorrow with my friends DS.
Tried everything i can think of to get it working, at the point of the update the card becomes unusable and needs to be reflashed by using another card.
I'll update you guys on what's going on.
Same as what i get, and i did the same process. i cant even load anything on my old firmware 3ds with this card now. i think the cards are now dead.
