The Sansa Updater follows the Forums by a few days. Download and install the new version here via the firmware link, and use the manual installation process. Be sure that the microSD card port does not have a card mounted.
You can install the firmware.sb file in either MSC or MTP mode, whichever mode you currently use will be fine, I’ve tested transfer in both venues.
By installing manually,you’ll heve the new lock function and a selectble 24 hour clock too.
