There are no firmware updates. This is for the V3 which is now discontinued.

IF you do find a V3 and need to update the firmware there are many youtube videos covering it plus forum topics (including one from me) however this is not relevant for the V4.

For those with a V3 who needs update guides, here's a written tutorial.
