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).

Ciao !

Hai un problema di partizioni ? Se si, forse i dati sotto potrebbero aiutarti a risolvere.

Vai in "rescue mode", se non ci sei gia molto probabilmente.

Code:
echo "rescue" >> /proc/stb/fp/boot_mode && reboot


Controlla se hai le partizioni come sul box funzionate sotto (e un DM900UHD),

Perhaps you could restore your GPT partitions this way... from rescue partition.

Devi lanciare il Putty in modalita seriale con velocita da 115200 bps, con il cavo collegato dalla porta Service del box al PC. Quando accendi il box dovrebbe darti informazioni sul terminale putty che potra aiutarti a capire cosa non va.

Gia con quello si potra capire qualche cosa. Questo fatto se si riesce, dovresti entrare nella console del rescue e da li potere fare i vari commandi fdisk per vedere come e la tua Flash. Poi da quello si potra vedere cosa fare.

Istalla Teamviewer, e fai il boot del box, a distanza si potrebbe provare con il tuo PC poi ad entrare sul box e vedere.
