DEM-3000
The abbrevation "DEM" most probably corresponds to Developer Experience/Engineering Model and was used for Prototypes of Vita Development Kits with the model/generation identifier 3000. (Just like DEM-1000 was for PlayStation Portable Development Prototypes!) Why they skipped the 2000, especially since the Vita was even internally named PSP2, remains unknown though.
The tailing letters like Gxx/Hxx/Kxx/Lxx etc, describe the revision followed by the 4th & 3rd digit of the serial number. The only exception makes the DEM-3000JEC which exists multiple times alongside each model after the Slider Design. Its generation can be identified by the seventh serial digit.
Early Prototypes were first given to bigger studios around late 2010 for them to getting to know the system and start developing. These units were quite fragile and had several issues like overheating so that Sony soon after dropped the PSPGo style slider design for a unibody with the DEM-3000K.
