About Player Firmware:
In case your device has encountered various problems that this release can fix, or if the same release comes to add certain features that you can make use of, then you should definitely take into account upgrading.
Usually, to do that, you must get the downloadable file (unpack it if necessary) and transfer it to the player through any available method, and start the upgrade process from the device’s setup menu.
However, given the large variety of music players and the many ways to enter update mode, it would be best if you read the product’s installation guide and initiate this task only when you have familiarized yourself with the steps.
To apply this firmware, take into account all the aspects mentioned above, hit the download button and update your music player. In addition to that, make sure you constantly check with our website to stay “updated one minute ago.”
