Rescue Mode Problem on DM9x0UHD

For rescue DM900 use usb cable and putty (serial port, 115200 bps 8N1, for the CFE stage, it's 9600 bps).

Start receiver and push ctrl+C to enter in cfe mode. Use usb stick for rescue file downloaded from internet.

Code:
ifconfig eth0 -auto
show devices
dir usbdisk0
boot usbdisk0:zImage-rescue-xxxxx


Then your receiver get in rescue mode and you can flash firmware (any tar.gz, tar.xz etc image file).
