What is Open Black Hole ?

It is an exciting new project from the same team that produce the Black Hole images.

This new project is based on the PLi git and coding infrastructure, which means it is not only Open Source, but it is also compatible with all PLi plugins, feeds and skins and it also features full online update support (for those users that do not like having to do a full reflash everytime there is an image update). We have just given it the Black Hole touch.

This means it has the Green Panel and Blue Panels as found in the standard Black Hole images, we have also added the Black Hole addons panel and included Full HD skin support, OpenGLes Animations and of course included Xbmc .

As with the standard Black Hole images, we continue to support Genuine Vu+ Boxes only and therefore our images are optimised for Vu+ boxes and will only work on these models (any Open Black Hole, or Black Hole images you see on the internet for other box models or clone models are not official images and we offer no support for those boxes or images).


Do I have to upgrade to this new Open Black Hole image ?

No you don't have to upgrade to the new Open Black Hole image, this image is completely separate from the original Black Hole image, this is simply a new image so we can offer our users more choice, if you are happy with your current image, then you can continue to use that image, if you want to try the new Open Black Hole image then you can do so.
