How to flash a Dreambox DM800SE via a Browser

Flash a new .nfi image onto the Dreambox DM800 HD SE from your web browser using its second-stage loader.

You can flash a new firmware image onto your Dreambox DM800 HD SE from a web browser using its second-stage loader. Follow the steps below.

What you'll need

  • The firmware image you want to flash — it must have a .nfi extension (you can't flash .img or other formats).
  • A DHCP server and a configured bootloader.
  • A browser and a network cable — connect the Dreambox to a switch, hub or router on your local LAN.
  • A working, intact second-stage loader.

These steps assume you have a DHCP server. If you don't, set up an IP address in the bootloader's serial setup.

Entering rescue mode

  1. Power the Dreambox down fully — use "shutdown" and switch it off at the power switch. Standby is not enough.
  2. Press and hold the power button.
  3. Switch the Dreambox on.
  4. The Dreambox takes the next free DHCP IP address from your router. How to flash a Dreambox DM500 HD via a Browser 1.jpg

Uploading the image

  1. On your PC, open a browser and enter http://ip/" in the address bar.
  2. At the bottom of the page, click the firmware upgrade link. How to flash a Dreambox DM500 HD via a Browser 2.jpg
  3. On the next page, select the .nfi flash image (other formats such as .img won't work), click FLASH! and wait — uploading and flashing can take a little time.
  4. Switch the box off and on again. The new image should now be flashed and working.

⚠️ Don't interrupt the flash. Once flashing starts, do not power the box down until it completes — interrupting it can corrupt the firmware.
