Dears: When I try to upgrade the firmware, once I've done all the steps (To press the start button, insert the battery, when light green goes release the button and wait for the red lithgt, connect to the wifi drone's network and so on); after those all steps the drone shown an additional error message regarding low battery level. The problem here is that I have a charger and I'm pretty sure the battery level is ok, so I can't upgrade the firmware....; thanks in advance for you attention and we keep in touch.

Hi DJI Wanda. Sure, I have a Tello, and of course it is the second time I have the problem after a long time don't using the drone; in the first time I follow the upgrade alternative but in this opportunity it doesn't work. The situation could be summarize in these points:

1. I have external charger and use all the time fully loaded batteries.
2. When I insert the battery and I try to start it, blink a green light slightly extended and after that blink a short red light and don't start.
3. In internet I've found alternatives about the firmware upgrade: keep pushing the start button while insert the battery and after green light blink release the button, the red light after permit us to connect to drone's wifi and could be possible to upgrade the firmware, but it is absolutely impossible!, all the time the APP is asking for a battery level need above 50%, and the battery is fully loaded.

Attached you can find some pictures. Please help!

Regards. (PD: Sorry for my english, I'm writting from Colombia).
