If your Clip Sport already has a Firmware newer than 1.28, you may not be able to install; according to user clipfan7.
I have not tested this problem myself. All my Clip Sports are running FW 1.28 and I do not plan to update.
FW 1.28 includes the ability to lock the player by pressing the “Back” button for about 3 secs. Unlock is the same.
Album Tracks can be played two ways: Music Mode and Folder Mode.
