I must have gotten lucky. I started the rc update, and it hung up-beeping, blue light flashing, but no message, nothing saying it was updating or failed to update. After about 20 minutes, I did what you're not supposed to do and shut off the rc. I turned it back on, and it gave me a message that hardware had a problem, call Dji. Doh!!! Well, I turned it off,plugged it into the charger a let it fully charge. Turned it back on, and was able to successfully download the update, but still had the hardware fail message. I got another message that update had downloaded and to press start to install. I did so, it updated with no issue, I rebooted and voila! Back in business.
