Hello, I accidentaly put an old SD card in the drone and turned it on so it started updating the same firmware (already installed). When i realized and switched cards it started doing a very loud beeping noise (as far as i have read is due to turning off the drone before update was done). In the correct SD card i downloaded the latest firmware again to be sure and deleted the old file (same update). Now it keep on beeping very loudly even without the SD card in. Any help?
