I have a Sansung Galaxy Nexus 4 (Verizon), it tells me the build is JDQ39. I want to set it up to dualboot, before I do I'd like to have the stock ROM on hand. I've downloaded ROMs for the JDQ39 build, but they expect the board to be 'Toro' not 'Tuna'. In looking at the list for factory ROMs it dosen't show a ROM for Tunq. It also appears that Toro, Mako, Magura, are linked to the Tuna board, what's going.
The reason I know my board is 'Tuna" , is the error msg when I try to flash a JDQ39 build ROM. The system - phone info only displays a build number.
