figured out how to bring dr soongue into the 23rd century

 

one of the problems is data is dead destroyed in a self sacrifice.

however B4 is nearly like Data, in most respects, even having Data's memories uploaded to him in the last film.

 

generally most computers come with a demo or a users manual, this one is titled "User's Manual" what happens is laforge finds a chip in B4's crainium and discovers it has a holographic matrix, when activated it turns out to be a hologram of dr soongue who after helping laforge get Data back online, Soongue uploads himself to Data's positronic neural net and takes overr Data's Bodie, sabotoges the enterprise enviromental systems knocking out the crew and escapes in a shuttle to a hidden secret base.
