Check the supported-device record first
CoreELEC publishes hardware-specific support information. Match the exact device and hardware configuration before planning a boot image or installation. A shared processor brand or a similar-looking enclosure does not establish complete support for networking, remote control, HDR or other features.
The project’s documentation distinguishes supported devices and generic reported hardware. Keep that support distinction visible rather than calling every bootable result an approved configuration.
Understand removable boot media
The project recommends removable SD/USB operation in its installation guidance. Choosing an image and a device configuration is an operating-system task, not the same thing as adding a playlist to an existing player. It can affect the device’s normal startup and access to its original system.
Read the device-specific requirements before writing media. Do not erase internal storage or replace a working system merely to resolve a media-account error. Keep an appropriate recovery path and follow the project’s current instructions.
Configure media only after the platform works
Confirm the remote, display, sound and network on the installed system before adding a source. Kodi and its supported add-ons provide the media workflow; the operating-system installation does not supply channel rights or a service account.
If a particular hardware function is missing, use CoreELEC’s device support information. A different playlist will not normally restore an unsupported network adapter or remote receiver.
Keep hardware and source failures separate
A boot problem belongs to the image/device configuration. A remote-control problem belongs to the input path. A source login or media error belongs later in the workflow. Recording those stages prevents a broad reinstall from hiding the actual cause.
