I've tried to upgrade a 640T Enterprise to 2.3.8 nearly 10 times now. The checklist is either incomplete, or it hangs at 99%.
I'm transferring the zip file to the root folder of a card formatted in the drone. I've also tried unzipping the FW file. I've also tried multiple cards and OTA. What's the trick here?
Thanks.
