Hi

Hi, we're sorry for the inconvenience. I would like to ask how many times did you try to update the firmware? I would recommend reformatting the SD card or change the SD card to see if there will be changes. You could download the latest firmware for the remote controller using this link: https://www.dji.com/phantom-4-pro/info#downloads. Please keep us posted on the latest progress. Thank you for your support.
