Hello,

Router: Zyxel DX3301-T0

Current firmware: 5.50(ABVY.3.8)b5_U0

New firmware: 5.50(ABVY.6.2)C0

I'm trying to upgrade the firmware on above router but it's giving me the error below?

Is it currently on custom ISP firmware (b5_U0)? If so, what are the next steps in upgrading to the latest 6.2 version?
