If you downloaded BH from this forum it should not be possible such a thing, as the file splash_auto.bin is always contained it the vuplus folder.
Try and put only the file I attach (unzipped, of course) in the pendrive.
I mean, you need the same folders structure you have to flash an image
vuplus/name_of_your_box
but the most internal folder must contain only this file.
Anyway, is far too strange, if you installed an official image downloaded from this forum, you have no BH bootlogo.
Unless... you installed it in OMB (multiboot): did you?
