What does that mean? CI decoding works fine on OpenBH (on all Vu+ 4k hardware).
We have been writing about this for many years.
Other images use a special enigma2 patch + special closed libraries from VU+.
This is not in the public, the code + libraries are added from the local repos during the build.
Moreover, these libraries are different for duo4k -- solo4k, etc.
And no one will just give you these libraries, even for money.
What else to discuss?
Therefore, I advised the author of the topic:
You can try another image(openATV/openBH).
