How to Flash a New Image on the Dreambox TWO UHD

Here's how to flash a new DreamOS image onto the Dreambox TWO UHD via its web interface, with a telnet rescue-mode fallback.

Prerequisite: download your preferred DreamOS OE2.6 image from the official source — Dreambox Two UltraHD images.

Flashing via the web interface

1. Power cycle: turn the receiver off using the rear switch, then back on.
2. Enter flash mode: as soon as the LED above the front button lights up, briefly press and hold the button upward, then release immediately. The device's IP address appears on your TV.
3. Open the web interface: enter that IP address (or http://dreamtwo)) into a web browser on a computer on the same network.
4. Click the Firmware button.
5. Click Browse and select your downloaded image file.
6. Important: make sure the Backup and Restore Settings options are unchecked.
7. Click Go! to start flashing.
8. After a "Finished successfully" message, click Click here to reboot. The receiver restarts with the new image.

Alternative: rescue mode via telnet

If the standard method fails, you can force rescue mode. Connect via telnet (for example using PuTTY) and enter these two commands in turn:

echo "rescue" >> /proc/stb/fp/boot_mode
reboot

After the reboot, the IP address appears on screen — continue from step 3 above.
