I just put a formatted (on pc) sd card in my DX and its wont get past the M logo on boot. Once I put the original sd card, it works just fine. I unrooted back to stock and tried it from a factory resetted phone and it just won't take this card. But when I put it into my pc, its recognized just fine so I know its good. Any ideas on why a new card is not allowing it to boot up?
added: oh and if I remove the new sd card, it boots fine.
