Happy new year everyone. FYI. Newbie here. I have purchased a used mavic pro, and it was working fine when i bought it. I was getting it all setup to fly when i got home, and i was hooking everything up. I noticed that there was message saying to update firmware, so i let it download and setup. Downloaded fine, and was installing, and the progress was sitting at 51%. It sat there for over 15 mins. When i started the updates, the battery power of the mavic was around 65%. And because the updating took so long the battery depleted to less than 10%. After reading on several forums, i downloaded dji assistant 2 for mavic. I have installed the software on several computers with no luck. What happens is that when i have the drone powered up, and plugged into the computer, i start up the assistant software, login, and nothing happens after that. The software sits there at the first page, showing a usb cord plugging into a port. Its like the software is not recognizing the drone or remote control. I have read several other people have had the same issue's. I have been in contact with dji tech support, and they weren't much help at all. So does anybody have any suggestions as to how to get by this issue so i can try and roll back update, or finish what it started?
