So, I just got my M3i Zero from the mail. I followed all the instructions, placed the proper F_CORE.dat/System files into the MicroSD card, then plugged the M3i Zero into the computer (with the USB power source). Now, for some reason, the LED Light just stays on. There's no blinking, no processing, nothing. It's just on. I've used multiple MicroSD cards with various formats and various System folders, but I can never get that LED to blink! Is there something wrong? What can I do?
