Google has posted the IMM76K factory restore image for the Verizon Galaxy Nexus online, making it available for those who have hacked their device beyond repair and need a path back. Using the posted files, anyone who was able to flash custom software to their Nexus should be able to flash the official version, and be back to square one -- ready to do it all over again. Do note that like the Sprint versions, these are provided "for reference only" -- but still contain the files you would need to build the software from code yourself if that's how you roll. Grab the image at the link below.
