First time drone owner and post.
I'm very interested in how some of you made out with this issue. Here's my story.
I purchased my Mini Flymore combo from Walmart prior to the official release. It shipped on Nov 11. I received it on Nov 15. Followed the instruction book, charged the batteries, and began my first drone experience. The first time I fired it up, the first firmware update (.02) automatically installed. Everything went like clockwork. I was very pleased. Flew several times with no problems with any batteries.
On Nov 29, the .03 firmware update showed up when I started a flight. I downloaded it without any fear because of my good experience with the .02 update. When finished, the battery that was in the drone showed an error 30074 and would not take a charge or operate in the drone. No problem at all with the other batteries. I called DJI, and they were of no help over several on-line chats and a telephone call. They had no fix, and were reluctant to help because I purchased it from Walmart. I returned the drone to Walmart, and reordered from DJI. I'm awaiting my Mini delivery.
Needless to say, I'd like to know how you all installed the .03 firmware successfully, as I'm going to be a little cautious this time. Thanks in advance.
