Hi I've just bought an M3iZero card. I have been trying all night to install the core file. At the first try, the led didn't show up at all. Finally it started blinking, but the blinking wouldn't stop. After about 20 minutes I took out the M3 USB power cable. I thought the problem might be that I used a (4GB) SDHC card. So I tried again with a 1G plain SD card but with the same result. I've been trying different versions of the core software but the result is always the same. he led just keeps on blinking. At some point I watched a video of the update process and I noticed that my card was blinking a lot faster than on the video. Mine blink 3-4 times a second. I've searched my ass of on this form (and will do for another couple of hours probably) but I haven't found a solution yet. can anybody help me out?
