And another trick to flash with the browser, but not using the front push button, and forcing the box ip to your own chosen ip in your network.
Also handy if your front display or panel does not work.

1. Connect the box with the network, and serial cable.

2. Use, startup DreamUp and set it to the correct com port, enable the Use Network, be sure that the Local IP and select one are the same, keep the Remote IP in the same ip area.
Example, Local/select one are both 192.168.0.5
Remote IP 192.168.0.10

With other words use DreamUp as you always did.

3. Press the Connect button, switch on the box.
If all goes well you see a connection to the box in the Log screen.

4. Let DreamUp as it is and use the Remote IP in your browser etc.
