Both DSIs were updated yesterday to login to the store, now M3i Zero card not working, getting the "An error has occured...." black screen. I have updated the core to the 1.6.1 file and the latest Sakura release from 9/21/10. So my question is was there an update to the dsi after the firmware was updated for sakura and core?? EDIT I found that the 1.4.1 u firmware has blocked these type of cards. Any word on update??
