Thank you Kevin, version 2.20(AQU.2)C0 was finally working, and after I was finally able to install in order the versions 2.20(AQU.6)C0 3.00(AQU.0)C0 3.30(AQU.5)C0 3.30(AQU.7)C0

Thank you Kevin unfortunately, also the 2.20 AQU.6 gave me the same error. at that point, I would try the release 2.20(AQU.2)C0 if this version work I probably really need to install all the release in order. Can you please provide version 2.20(AQU.2)C0?

If anyone has this version to share I can try it 

Hi, I already tried to download it from the official site but there are only 3 versions 3.30 AQU.5 3.30 AQU.6 3.30 AQU.7 and all 3 versions gave me "errno: -42008 errmsg: Firmware not compatible!" 

I was reading comments about this error and I found another person with the same problem with the model USG 100, he solved it by installing also all the patches in sequence, annoying but effective, in my case, I should install in order: 2.20(AQU.2)C0 2.20(AQU.3)C0 2.20(AQU.4)C0 2.20(AQU.5)C0 2.20(AQU.6)C0 3.00(AQU.0)C0…

Hi, as you can see in the picture is what I did.

HI, Thanks for your fast reply! I tried to Update the firmware version 3.0 that you sent me, I still get the error "errno: -42008 errmsg: Firmware not compatible!" inside the Firmware page, the model on top is "ZyWALL USG 200" so it is right the other info is Boot Module: 1.12Current Version: 2.20(AQU.1)Released…
