Flashing Failed

1 The unit does not work after flashing

In case that your unit is not operating correctly after flashing process, you can use the following guide to make it work again.

Important question is, why it failed?

Possibilities are:

1. Connection between unit and computer is not stable (check the cables).

1. Software issue (installed driver in your computer is not correct) or downloaded firmware had a ".man" extension instead of ".4df" [Most common].

If you are on Windows, please re-install the software with the option for Driver installation. Then it will install correct driver. Then reboot the PC.

If you are on Mac, use this driver: OSX 11.0 and older

Other drivers will very probably not work correctly - especially for the flashing process!

Prerequisities for the recovery process:

1. Correct driver in your operating system.
2. Status LED of the unit must flash for a short time during power up.

2 How to revive the unit

1. Connect the USB interface to your PC and the unit (SYS port).
2. Start the software. Select NO when prompted for Demo mode.
3. Go to the Update tab and select firmware you want to flash (4df file extension).
4. Power up the unit (from your BEC or a battery). Immediately after power up, flashing should start.
5. Press the Flash button (and then OK) - you should see "Recovery mode" label in the software.
6. In 20 seconds, unit should be operating again without any issue. Your settings are untouched.
