For those of you that own a Verizon version of the Samsung Galaxy Nexus and are running a custom ROM then I have good news for you. Google updated its Developers site with the 4.2.2 factory image. So if you botch your phone or have to return it to Big Red you can bring it back to a stock state. Those of you on Sprint and happen to own that version of the Galaxy Nexus will be happy to know that the 4.2.1 image was also uploaded. So head on over to the source link below and find your respective image. Happy flashing!
