Hello guys please help,
My DM900 after switch on remains in rescue mode regardless pushing the stand by button or normal boot.
IP address and Telnet control OK however when I try to open the webIF to flash the box, there is no "Dreambox start page" but this text "Content-Type: text/html;charset=utf-8" appears.
When I try to reflash the firmware I get this:
root@dm900:~# wget https://dreamboxupdate.com/opendreambox/2.5/stable/images/dm9
00/zImage-rescue-3.14-r0-dm900-20190911.bin
Connecting to dreamboxupdate.com (82.149.226.170:443)
wget: server returned error: HTTP/1.1 400 Bad Request
root@dm900:~#

I get this bootlog:
