Hello ! I bought phantom 3 4K and did a proper firmwire update. I put the SD card in my PC to check the .txt file. Then I thought i dont need these files and i deleted them . OMFG Basically - now if i launch the system, it told me firstly i should do a firmwire update. I told it to do it. It immideately went to 100% but its not completed and it never will be completed. when i want to use camera, it tells me, I should wait untilt the update is done. So, its a dead end. Every other phantom has that reasonable USB port on remote. I dont have it. What should i do now ? Send it back to the factory ? Facing a mental breakdown right now. Big thanks in advance !!!
