So i have my oldish/older USG20w-VPN from a few years ago when i bought it and im running 3.3 at the moment. I went to go on the site just to see if there is anything new from 3.3 and now there is 4.16 listed. So i am super excited to try out this new firmware, i download and extract it. Go to the Web UI, go to select and upload the BIN. everything seems good until i get the "Firmware is not compatible" error.
Iam i running on too old of a hardware version of the USG20W? It is a ZyWall USG20W:
Boot Module: 1.14
Current Version: 3.30(BDR.7)
Released Date: 2015-01-13 16:29:11
Judging by the guides they have posted, i'm guessing there is a hardware v2/this won't work with non v2?
