Firmware Upgrade Path

If your Humax came with software version 1.03.06 or above If your Humax arrived running software version 1.03.06 or later then do not downgrade it to an earlier version. It is safe to install the customised firmware based on 1.03.12.

The procedure for upgrading your customised firmware varies depending on which software your Humax is currently running and the version to which you are migrating. Refer to the tables below to find the appropriate instructions. These instructions reflect the upgrade paths which have been tested. Others may be possible but proceed at your own risk.

In the tables:

Official y.y.y 

indicates an official firmware release from Humax

CFW x.xx/y.y.y 

indicates customised firmware version x.xx for official firmware y.y.y

Links to the files can be found on the Firmware Downloads page.
