Firmware is software closely associated with the operation of a hardware device, often distributed by its manufacturer. Updates can affect stability, compatibility or device features, but their scope varies. Firmware is different from an individual player's app update, and changing one does not guarantee that every separate application or media source will work differently afterward.
A practical example
A television manufacturer may release a system update while a player developer releases an independent app update. Recording both versions helps support identify whether a problem began with the device software, the application or another part of the viewing setup.
A common misunderstanding
Use the manufacturer's supported update route and instructions. A file intended for another model can be inappropriate, and interrupting a firmware update can create problems beyond the original playback symptom.
