Firmware update

HI, I am new to this, I have an LG MS408D, I believe that the firmware updates Harmony packs work with it.
Can any one tell me , DO I need to have updated each Harmony pack to my LG machine, or can I just update the latest Harmony/Custom pack ?
Will the latest Harmony include all the features from earlier updates.
Cheers
Roger

Hi Roger,

I'm not using the Harmony pack and I don't know the MS408D, but I'm quite sure you can install the last relase directly.
No need to install older versions first.

Regards,
