I bought and received my drone the first of January. Once I got it out and set-up, I needed to do a FW update (.0200). I could not get it to work either thru the RC or DJIA2. I sent it back to the dealer that sent it back to me 2 weeks later updated. SO the new update came out, I'm prepping my bags as I am heading to Thailand in the am, and again, cannot update the Mavic. I read some posts online that said to ensure your SD card is formatted, full batteries, and USB from DJIA2. I tried, no avail. I also noticed that the bottom of my bird was getting extremely hot during the process, almost to the point I couldn't touch it. ((That sounds like another issue I will take up with warranty when I return, but I don't think my cooling fan is kicking on)). So I let it completely cool off, and I attempted the download again. This time, I held the Mavi in my hand and blew in the front grill behind the gimble, on the bottom of the deck and in the back grill. This process took 15 minutes. But it worked. So I am curious if anyone else having this issue of firmware upgrade failure is also having an overheating issue due to the cooling fan not kicking on. Good luck and let me know.
