I recently updated my Nintendo DSi to the new Firmware (4.5.0-10x) and had to upgrade the M3i Zero GMP-Z003 to the newest core. Of course I did not read the instructions carefully and tried to update directly with the Core data file V4.5.0. As suggested I tried to flash the card with the older version (4.9a X and 1.49a X) but when starting with an Nintendo DS (with the old Firmware) I only habe a black screen when booting. What can I do to get the card working?
