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).

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), Quote: opendreambox 2.5.0 dm900 >>> Your Dreambox has booted into RESCUE MODE. >>> Please log in as user 'root' (no password required), >>> then run 'help' to get further information. dm900 login: root root@dm900:~# fdisk -lu Disk /dev/mtdblock0: 2 MB, 2097152 bytes 255 heads, 63 sectors/track, 0 cylinders, total 4096 sectors Units = sectors of 1 * 512 = 512 bytes Disk /dev/mtdblock0 doesn't contain a valid partition table Disk /dev/mtdblock1: 0 MB, 131072 bytes 255 heads, 63 sectors/track, 0 cylinders, total 256 sectors Units = sectors of 1 * 512 = 512 bytes Disk /dev/mtdblock1 doesn't contain a valid partition table Disk /dev/mtdblock2: 0 MB, 131072 bytes 255 heads, 63 sectors/track, 0 cylinders, total 256 sectors Units = sectors of 1 * 512 = 512 bytes Disk /dev/mtdblock2 doesn't contain a valid partition table Disk /dev/mtdblock3: 14 MB, 14417920 bytes 255 heads, 63 sectors/track, 1 cylinders, total 28160 sectors Units = sectors of 1 * 512 = 512 bytes Disk /dev/mtdblock3 doesn't contain a valid partition table Disk /dev/mtdblock4: 33 MB, 33554432 bytes 255 heads, 63 sectors/track, 4 cylinders, total 65536 sectors Units = sectors of 1 * 512 = 512 bytes Disk /dev/mtdblock4 doesn't contain a valid partition table Found valid GPT with protective MBR; using GPT Disk /dev/mmcblk0: 7634944 sectors, 3728M Logical sector size: 512 Disk identifier (GUID): 30f082cc-2877-4689-9b2b-e1812454a613 Partition table holds up to 128 entries First usable sector is 34, last usable sector is 7634910 Number Start (sector) End (sector) Size Code Name 1 2048 65535 31.0M 0700 kernel 2 65536 2097151 992M 0700 rootfs 3 2097152 7634910 2703M 0700 data Disk /dev/mmcblk0boot1: 4 MB, 4194304 bytes 4 heads, 16 sectors/track, 128 cylinders, total 8192 sectors Units = sectors of 1 * 512 = 512 bytes Disk /dev/mmcblk0boot1 doesn't contain a valid partition table Disk /dev/mmcblk0boot0: 4 MB, 4194304 bytes 4 heads, 16 sectors/track, 128 cylinders, total 8192 sectors Units = sectors of 1 * 512 = 512 bytes Disk /dev/mmcblk0boot0 doesn't contain a valid partition table Tienici informati, Admin DM920UHD : Quote: root@dm920:~# fdisk -lu /dev/mmcblk0 Found valid GPT with protective MBR; using GPT Disk /dev/mmcblk0: 15269888 sectors, 3360M Logical sector size: 512 Disk identifier (GUID): a157dc9b-d004-44e6-a25a-9c0d96d709f6 Partition table holds up to 128 entries First usable sector is 34, last usable sector is 15269854 Number Start (sector) End (sector) Size Code Name 1 2048 65535 31.0M 0700 kernel 2 65536 4194303 2016M 0700 rootfs 3 4194304 15269854 5407M 0700 data Perhaps you could restore your GPT partitions this way... from rescue partition.
