I see your point. This is the first time I have seen a firmware update change the hardware version but I have only been using Omada products for less than two years. That update occurred when there was a name change from Jetstream to Omada and I would guess that the hardware in the initial Omada model was the same hardware as the Jetstream model and only the outer case was changed. The version number change was probably done to eliminate confusion between the two models.
If the device's web interface now displays v3.20, then that is what you should always use to upgrade the unit.

Hi @msankowski
If you have SG2008P V3.20 and SG2008 V4.20, then please try to update the firmware in this pre-release post with the same hardware versions which point to 3.20.20 and 4.20.20 respectively.
