Ok, so more searching into this has produced something interesting. While looking up any possible way to further identify similar model phones in hopes of piecing together a root method for the H866C, I found my way to the fcc.gov site where a search of the FCCID number QISM866 (found under the battery of the H866C) turned up something interesting (click HERE to perform your own search for QISM866 as I was unable to link directly to the search results) apparently the H866C and the M866 have the same exact FCCID! Those more versed in such please correct me, but I assume that means they are basically the same phone. Now I have to ask - is the root process dependant on the software or the hardware? Or both? Does the root process depend on what phone is being rooted or the carrier specfic software or a combination of these?
