    Signal lost. I have been using my drone, but today it told me to do an update, and now I can't get it to work. All I get is a signal lost code.

    Just went through this. Had to update the RC fw and AC fw. I had 1.4 and went to 1.8 on the AC. Then it worked. I needed a bunch of help via this site to get it done....

    mike the pilot, you need to upgrade the firmware on both the Phantom and remote controller separately. If you only installed the remote controller firmware from the DJI GO app, then that would definitely cause this issue. You can find detailed firmware installation instructions here.

    Detailed procedure is given by msinger. Read it and understand it well before updating your FWs

    A summary is given below:

    You need to update both RC and Aircraft. As you have already updated RC, you need to update aircraft only now.

    Go to DJI ate and read the full procedure. A brief procedure is given below :

    1. Download the FW for your model from DJI site
    2. Unzip to extract bin file
    3. Save the bin file to SF card of the aircraft and plug it into it
    4. Keep RC off but switch on aircraft
    5. Led on gimbal will start flashing green and red and aircraft will start beeping
    6. You may have to wait for 10-30 minutes
    7. Wait until gimbal led turns solid green
    8. Turn off aircraft

    All is done. To check :
    9. Turn on RC
    10 Turn on DJI go app
    11. Turn on Aircraft
    12. RC will establish connection with Aircraft
    13. Check versions on DJI go app

    Alternatively you can take out the SF card and a txt file will be generated. That file should say success.

    Read detailed procedure before starting update.

    You may need to Calibrate IMU and Gimbal.
