The DroneFighter Firmware update failure

[xueyul...@gmail.com]

 I found that there are new firmware on the website.

http://dev.byrobot.co.kr/documents/kr/products/dronefighter2017/

       So I want to upgrade the DroneFighter firmware on hand.

After update，the Controller seems work in normal. But the drone 

is not working properly. All leds are lit，and cannot pair with the 

controller.

       And try to update firmware again, but the Windows cannot find

the driver(and cannot find the COM port) .

       Is there any other way to get it back to work?

Is it possible to upgrade using UART?

      Can you provide firmware recovery?

Hello.

I think there were some problems while update drone firmware.

Have you done update again?

Somehow bootloader can be broken, but it is very hardly happen.

First of all, Remove battery.

Second, Push a button on the drone.

Third, Connect battery while button pressed.

When bootloader is working, All leds are lit.

If bootloader is fine, you can find COM port when drone connected with the computer.

If bootloader isn't working, there is no way to help you by online.
