Dear colleges I try to load the new firmware and some things getting rare in the procedure, first was all ok I downloaded the version from DJI page the latest for professional, then I put the SD in the slot (gimbal) and beginning the sound that indicates the process is started... Then after 15 approx the lights of motors was Off and the blinking led's was solid red ... Ok I presume was fail the process so I power Off the aircraft and check the file ... The file just say upgrading ...... And nothing more ... I put again the SD and the aircraft beginning to sound different .. Lights off and very intense and noises sound, but the led's change red to green and repeat over and over like this. Now I cannot to load any firmware in the aircraft just this awful noise ... My question is some knows how to restart the aircraft ?? How I can again load the firmware with any problems ? From already thanks !
