Hello.

I have a problem with my DM 900.
The problem is described as "DM900 red light" - only the power and LAN LEDs are lit in red.

No possibility to enter recovery, no LAN communication.

The only communication is via the service connector and reading via putty.

I tried resuscitation via OptiFlsher, but I can't do anything without activating the software, and the project is probably dead.
Do you have an idea for reviving the box?

I probably can't help you with it because, Searching to..

Than this is a difficult issue which are more common and often is unsolvable but In some cases this may work,
Putty in Serial mode....
Change the serial mode Bps to Bps 9600 and press the CTRL/C buttons on your keyboard, and switch on the box.
When that's working than you hopefully get into BOLT mode which gives you the possibility to flash the rescue-dm900.bin file via usb with the following command.
BOLT> show devices
BOLT> dir usbdisk0
BOLT> boot usbdisk0:/rescue-dm900.bin
Notes that the rescue-dm900.bin file must be present on the usb stick.
You may find the file on dreamboxupdate dot com.
And take the newest one.

But it may also be a hardware issue.

DDR1: =@ ffe0e780 <= ffe0df10 MEMSYS-1 @ f1180000
MEMSYS ERROR: 00000001

as a bad memory block.
