Firmware of the sansa fuze.
A Firmware is software that is integrated to a hardware component.
In the case of a digital player such as Fuze, is the software to operate the player. Just like Windows or Linux computers running.
In the case of the Fuze, it's important to know that even if the player is still young, he is already at version 2.
For this reason we speak of Fuze and Fuze V1 V2.
The transition from v1 v2 by SanDisk that justified by changes in the main electronic card.
We therefore call his little changes "minor" because it does not affect the normal operation of the machine to the user. Only the firmware famous works differently, or usefulness of a different version of it for each version of Fuze.
Note that we are talking here of the official firmware released by SanDisk, another firmware is also available, RockBox for which you can find more info on it in the section which is specifically dedicated.
So, at each update firmware, SanDisk publishes a version 1 and version 2.
If you use the software update provided by SanDisk (the Sansa.Updater), it will download it even the latest version that suits him.
However, if you want for one reason or another go back to an older version of firmware SanDisk will not do so through their application since it is fully automated.
But fortunately we are there!
You will find the following item (Download and install) the procedure and the files required to install the version you want for your Fuze.
