I am trying to an update on my new  Tello and noticed it is quite hot. How long does it take to do the update, I've been at it for awhile.

Make sure your mobile device is linked to a Wi Fi modem. If the update has taken too long, you may want to redo the update. Make sure your batteries are charged to 100 percent. Turn everything off for 10 minutes then start the process again.

I was performing the update , same happen, the temperature raise, and then , the lights gone off, and now I can't power on the drone, no lights during charging either. :-(
