DM430E - Bricked

[george]

Hi,

We bought two DM430E 0-0-0-0 displays and one of them is bricked on flashing the test application.
The application flashed successfully and the GUI has changed as expected.
However the display is neither sending CAN messages nor recognised in "Recover ECU" for reflashing.
Looks like it is bricked.

We are using PCAN View, with RP1210C interface.
Could you please help to resolve this?

Service tool version is: 2024.2.5.6053

Any thoughts?
This is a stopping issue and I am unable to get it resolved.
Is there any technical team I can talk to or an email where I can email the issue further?
Thanks.

I tried to access the command line mode and got the following log. Still the download is failed.

As I have two units, and here is the log from the bricked unit. No heartbeat of CAN messages. Display screen comes back normal with the previously programmed screen.

Are you sure you're on the right baud rate? You won't be able to communicate if your screen has switched to 125k, 250k, or 1M with a gateway set to 500k.

[Lukey]

G30RG3 maybe be right.

The default baud rate is 250kbps, possibly if the display has gone into bootloader and reset, its rate is now 250kbps.

Have you tired to recover the ECU? this will get it back to a state where you can download/flash a new lhx file.
