Jelly Bean factory images are now available from Google for a good portion of the Nexus lineup of devices. If you happen to own a Nexus 7, Nexus S (sojua or soju versions), or the Galaxy Nexus (yakju and takju versions), then we suggest downloading these files and keeping them in a safe place in case of future software troubles. Down the road, these could save you from a horrible custom ROM flashing fiasco and bring your device back from the dead. No love yet of course for the Verizon toro version, but hopefully we’ll be shown some love too in the future.
