need help desperatly!! i recently upgraded my phantom 3 professional to v1.4, had no trouble with previously version. i think my v1.4 was successful, but i didn't realize i had to check camera status led, i checked text file and it read success. so i mistakenly downgraded to previous v1.3.2. the downgrade resulted in loud siren like continuous beeping. i formatting the sd card and reinstalled v1.4 making sure it was a bin file only. i had text file reading success, but the video feed on my mini pad 2 was distorted, the camera feed was unstable and would switch to video feed with the distortion, also file from sd card was distorted. so next i reset all on rc. i formatted sd card again downloaded v1.4 with bin file. twice i have tried to reinstall, each time 2 hours or more. camera led flashing red and green, camera tilted and no beeps from unit. SUGGESTIONS PLEASE
