Hmm sorry to hear it is not working, it could be the DYNAUDIO.
In fact the image is the same only when DYNAUDIO is activated there is a second overlay image (800x130).
I'm not providing that second image and maybe that is why it fails to install the bootlogo.
I have a test unit and try a bit more on the DYNAUDIO part.
So indeed for now it is better to not use it for DYNAUDIO.
