    For those That use an LG phone as a monitor on the P3S, are you able to downgrade the firmware using an LG phone? I can't seem to get data to work, and find the software, while connected to the RC Wi-Fi.

    I used my Lg G5 for this..
    Please read my step by step..
    I will add that it is also possible to upgrade or downgrade with just your "USB Host" phone...
    No PC or Mac NEEDED!!!
    Step by Step Downgrade from 1.8.1 to 1.7.9 P3S
    With Only USB cable !! :)
    Turn on R/C and A/C....
    Connect the DJI go app.. Go to the main screen like in the video...
    Connect the USB cable to the A/C and PC...
    Open the drive that comes up on PC...
    Copy the P3C_FW_V01.07.0090.bin file to the root directory of the drive... Remove USB cable..
    Turn off A/C....
    Turn on A/C...
    A/C will start "downgrade" you will see it in the app (like video)
    Once at 100% complete... (leave on)
    Reconnect USB cable...
    Go back to PC... Delete the P3C_FW_V01.07.0090.bin... (must)
    restart A/C and R/C ...
    Done... :)
    Always Run an IMU re-calculation...
    After Every Firmware update...
    Whether it says it needs one or not!!
    Please :)
    No format... No deleting of files... Just copy P3C_FW_V01.07.0090.bin on the Root folder of the card...
    That is All... :)
    If you have a Sd card reader you can use it.
    Just put the bin on the root folder of the sd card put it in the drone and Connect the DJI go app..
    Go to the main screen like in the video...
    Turn on A/C...
    A/C will start "downgrade" you will see it in the app (like video)
    Once at 100% complete... Turn off every thing pull out sd card and delete bin if it is still there(format card)
    If you have used this same card for any other update it is best if you format the Sd card :)
