A Step-by-Step Guide to Installing CoreELEC on the Dreambox One UltraHD

This guide explains how to install CoreELEC (to run Kodi) on a Dreambox One UltraHD from an SD card — and how to switch back to DreamOS afterwards.

What you'll need

• The CoreELEC image file for the Dreambox One.
• A flashing tool such as Balena Etcher or the LibreELEC USB-SD Creator.
• A spare SD card.

Installation

1. Download the CoreELEC image. Get the correct .img.gz file from the Dream Elite server: Dream Elite server.
2. Prepare your SD card. Insert it into your computer, open your flashing tool, select the downloaded .img.gz file and choose the SD card as the target, then start. This erases all data on the card.
3. Boot into CoreELEC. Once flashing finishes, insert the SD card into the Dreambox One's card reader and power on — it boots automatically from the SD card into CoreELEC. The first boot takes several minutes and may include an automatic restart.
4. You're ready. After setup you can start using CoreELEC and Kodi. Bluetooth remotes are usually detected and paired automatically.

Switching back to DreamOS (Enigma2)

1. In CoreELEC, open the Shutdown Menu (top-left corner).
2. Select Restart or Shut Down.
3. Once the Dreambox One is off, remove the SD card.
4. Turn the device back on — it now boots into DreamOS.
