The firmware upgrade option will be only available when the player contains no disc or completely stops. Firmware is system software with functions for controlling the player.
Since specifications for Blu-ray discs are new and being constantly improved, the Blu-ray discs issued after production of these players would adopt new specifications and have new functions. Therefore, to ensure optimal viewing experiences, the player firmware has to be updated from time to time.
We strongly advise our users to upgrade the firmware through Internet directly from the player. USB installation is restricted to Magnetar technician assisted instruction, resellers, or professional use only.
