The full Nexus factory image flashing tutorial [Video]
By popular request, here’s a straight forward video on flashing factory images on your Nexus device. No matter what the device may be, you can use factory images to revert, update or restore your device. This may also help Nexus users who are facing the dreaded boot screen of death.
I have used my Nexus 4 to be the test device for the tutorial, but as always, make sure to grab the appropriate image for your device (e.g do not choose a Nexus 5 image for a Nexus 7).
