Prepare an SD card (class 10) / USB flash drive as follows;
NOTE: On some devices, only 1 USB port is able to boot the device, you may have to try them all to see which one works for you, some boxes are also unable to boot from a USB drive.
- Download the latest .img.gz file from here.
- Use Rufus (or your preferred image writing software) to burn the downloaded image file to your SD card / USB flash drive.
- If successful, the SD card / USB flash drive capacity will be shown as 512MB, this is OK as there is a second (hidden) partition for CoreELEC user data.
- Browse to the Device Trees folder, now present on the SD card or USB flash drive, and copy the correct .dtb image file for your device to the root folder of the SD card / USB flash drive, and rename it to dtb.img.
To boot the system for the first time you have to use one from the following methods, sometimes only one of these methods will work!

Note: You must be using a device tree from 28-10-2017 or later. You can check it by running this command: cat /proc/device-tree/le-dt-id. If this command gives you device tree name, you have all that is needed for an automatic dtb update.
