I just bought a 3DS and ordered an R4i Gold 3DS flashcart from r4i-gold.com (this was a mistake - I thought it supported the new 4.20-9 but it didn't). Today the update was released on r4i-gold.com, but when I place the files in the sd card and load it up on a DSlite to update, it tells me this cart is already updated. "no need update. please power off". When I try it in my 3DS I just get an error message. Any clues to what might be going wrong?
