Firmware Downloads

Below you will be able to download the latest versions of our firmware as well as any Beta Versions we may be testing in-house.

Please Note:

A Beta Version is defined as a "pre-release of software that is given out to a large group of users to try under real conditions. Beta versions have gone through alpha testing in-house and are generally fairly close in look, feel and function to the final product; however, design changes often occur as a result".

While it offers you the opportunity to play with many new, and cool features there is also the potential for bugs or "quirks". We would greatly appreciate it if you would let us know so that we can address them.

Firmware with the status of "Public", is official public firmware that has already gone through the beta stage. You should always download the latest version of the firmware available.
