[VU+ Duo2] Error when searching for software update

[II AnDo II]

Every time I search for a software update (menu- setup - software update)
I get the following error and have to power off my box.

Current version 4.1.016

You are on too old a version to online update. Fresh flash and setup from scratch is required.

Ok thanks, will the settings backup and restore still work?

No, you'll have to setup from scratch.
