I have three original DJI batteries. I upgraded the firmware on the first two, and while upgrading the third one, an error popped up at 81% that the upgrade process has failed. And now I have the issue as shown below, and the motors will not start, with that specific battery. I tried running the firmware upgrade again, but the same error pops up saying that the firmware upgrade has failed. Currently I am draining the battery in an attempt to "reset" it perhaprs, and I have also cleaned the small square contacts, to no luck. Any ideas on how to fix this?
