Went through one heck of an experience updating firmware last night on my one week old Phantom 4. Yikes !! Turned it into a brick but after many hours and help at the DJI forum I now finally have it back up! Extremely happy as I was getting ready to ship it back and it flew like a dream so that was super disappointing. Anyway here’s the thread as it might help someone else out. DJI really needs to fix this updating firmware thing.
