Wow, the M3 Team is looking to capitalize on the 4.5.0-10 money. Their M3i Zero GMP-Z003 flash card now runs on 4.5.0-10 firmware. Grab the 2 files you need to upgrade from http://www.handheldsources.net/M3DS/Download_M3DSR.html 1) Run the .nds file on a DS/DS Lite/DSi (NOT 3DS!), when it's done (~5 seconds) remove the flash card from your DS. Now remove the micro SD card and erase the .nds update file. 2) Place the F_Core.dat file on your micro SD card. Place the micro SD card into your M3i Zero GMP-Z003, and plug in your USB updater cable and wait until the red flashing light comes to a complete stop. Now you can remove your USB updater cable from your USB port, and take the other end out of your M3i Zero GMP-Z003 flash card. Go ahead, remove your micro SD card, and erase the F_Core.dat file. 3) Done! It works well! I own a M3i Zero GMP-Z003, so I've already updated my flash card. Enjoy!
