I have just updated my P3P and the lights stop flashing and am getting a continuous beep on the aircraft. I flew the aircraft few hours ago. Help pls anyone . Thanks

Confirm version in your DJI app. Check the .txt file on the sd card in the aircraft. If the versions show that everything has been updated (aircraft and all batteries) remove the .bin file from your sd now.
It will beep after upgrade, until you power cycle. Just make sure the light on the camera is green, not green/red blinking.

Hello larryallison，please try to format the SD card and extract the bin file to the card. Then do the upgrade again. If it keeps to fail, please post the log here by the following steps:

1. Enable the option of viewing hidden files in your OS. Below are the websites where you can check how to show the hidden files in your PC.

2.Enter the root directory of the SD card, then find the hidden folder MISC and enter it. There is LOG folder in it.

  

3.The LOG txt file is under the LOG folder.
