Keep the model’s status accurate
The manufacturer points new visitors to a different model. The saved Premier 4K Pro photograph therefore identifies existing hardware; it should not be presented as evidence that this is the current model to buy.
Use the support and software information for the unit you own. A replacement model’s firmware, ports or application behaviour should not be imported into an existing Premier guide merely because both carry Dune HD branding.
Understand the two software paths
Dune describes the Premier as combining Android TV streaming with a separate Dune HD media centre. Local media-library functions and a third-party television player can therefore be handled by different applications and processing paths.
When a video fails, state which path is involved. A local file, household NAS share and remote subscription source have different access and format requirements. A success in one is useful evidence, but it is not proof that all three are configured.
Use storage deliberately
The manufacturer documents a drive-rack/local-storage role for this model. Follow its physical drive requirements and instructions before adding hardware. Keep local-library storage separate from a player’s app data or any authorised recording workflow.
Do not erase a drive or replace device software as the first response to a source-account error. Preserve a backup and recovery information before changes that could remove a working library.
Keep an existing-owner test record
Record the model, installed firmware, application used, media location and the exact symptom. This allows a technician to address the correct Android TV or Dune media-centre layer while retaining the honest discontinued-model context.
