I have tried upgrading the firmware via the Android and iOS app unsuccessfully. This is what I have done: 1) Powered on the controller and the P3 2) Downloaded the update through the app 3) Clicked update in the DJI app The following error message continues to popup: "No SD Card inserted, unable to upgrade" However, the SD card is inserted. I have tried multiple SD cards. I have also tried putting the downloaded "P3C_FW_V01.03.0050.bin" file in the root of the SD card to manually upgrade (I have read this is not possible on the standard edition). The camera view shows nothing and I am unable to upgrade after several attempts. I have tried contacting DJI support and I have not received an email back (it has been 2-3 weeks now). Please help. How do I get this update installed and get my camera working? Thank you.
