Yesterday i did update the firmware of my Phantom 3 Standard from 1.2.4+ to 1.5.7 version. When the process was completed, i checked on SD card, it showed 'success'. but when i checked my firmware version via dji go app, it showed 'N/A'. The rear LEDs flashing yellow quickly. I tried to relinking to RC but still not connected. RC signal lost and props couldn't be started. Is there something wrong? What should I do? Need your help. Thank you.
