I have successfully used my P2 Vision Plus for almost a couple of years, a hundred flights with no issues. I have been planning a big expedition into southern Utah for months. Today I decided to getting around to upgrading the firmware on my remote controller and phantom UAV. the upgrade failed, and it would no longer power on. I "bricked" it. That is what I learned AFTER I searched these forums on Phantompilots.com Also learned that there is no easy or clear solution. And that DJI has been of no help. What a HUGE disappointment! I have no time to research and experiment with soft and hard resets, or wait for the snail like, understaffed, DJI support team to get back with me. And I had some great flights planned over some stunning, legal, areas of southern Utah. But my fellow expeditions will not wait for me. We have to leave at 6am tomorrow. Why does DJI allow this situation to exist???? I am very disappointed and angry that I have to leave my Phantom at home. If only I hadn't tried to upgrade my firmware. Never upgrade DJI firmware!!!! All they care about is developing better drones and selling you those.
