Hello,
If you need to re-flash your DM you have two options through web interface in ***STOP*** mode or through RS232 cable with DreamUP.
For re-flash your DM with ***STOP*** mode you will need to have your DM connected through LAN cable to a router with DHCP enabled (dhcp is the service in the LAN which allocate IP's automatically) and an conputer conected on the same LAN.
To put your DM into ***STOP*** mode you need to unplug the power cord and press power button before plug the power cord back, you need to keep pressed the power button after you plug in the power cord until the ***STOP*** message appear on your DM's OLED display.
After your DM will enter into ***STOP*** mode, on the OLED display will appear and message regarding DHCP and shortly after will appear an IP address.
You need to access this IP address with you browser from an computer in the same LAN with your DM, after accessing the IP with an browser you will need few options on web page loaded from that IP, please click "Firmware upgrade" link.
For re-flash with DreamUP you will need to have an NULL modem cable and an computer with RS232 port (ie. serial port), an usb to RS232 adapter usually works on newly computer which does not have RS232 anymore.
The procedure is simple, unplug power cord from your DM, connect your computer with RS232 cable to your DM, start DreamUP application and click "connect" button, after plug the power cable to your DM.
The DreamUP app will start to upload the flash-loader into your DM, after the process is done, you need to click on "flash" button to load and flash a new image on your DM.
Please use last known good image that worked on your DM.
Also, please keep in mind that you need an patched image to work with DM Clone.
If you use the DreamUP variant you will need an pached DreamUP version in order to work.
If you have any issues please let us know.
Good luck,
Marc
