USG20W firmware

EmilK

Hello,
I have a Zywall USG20W unit, with firmware 3.30(BDR.9) / 1.17 loaded.
I see there is an update 4.25 version, but i cannot install it.
I get a massage that is incompatible.
Is it for some newer USG20W units, or is there an upgrade process i need to follow?
thank you

Hello Emilk,
The current firmware version of USG20,20w,50,100,200,300,1000,2000 is 3.30(XXX.9).
However, the firmware 4.25 is supported by different platform.
