The 2.0 that was 'preiunstalled" on your Opus was not the same build as the Public 2.0 version and there is no public 2.0 that support Colored Opus. Using a Public 2.0 build will semi brick a Colored Opus.
I never say that you can't download or find the public 2.0, just that the public 2.0 is NOT*COMPATIBLE with Colored Opus, and it MUST NOT
be used with Colored Opus. There is a bug in the Bookeen upgrade tool that will make the 2.0 update run on Colored Opus, where it should refuse normaly.

The version your installed is NOT*COMPATIBLE with your Opus, so don't expect it to work.
