Google has promised that it will release Android 4.2.1 factory images for all Nexus devices as soon as the update is pushed OTA (over the air).
Well, it looks like the company has just delivered what was promised and those who own a Nexus smartphone or tablet can now download their Android 4.2.1 factory image via Google devs site.
Nexus 4, and 7, as well as Galaxy Nexus (yakju and takju) have already received their factory images. The only problem seems to be with the Nexus 10, which is still stuck on Android 4.2 due to a slight issue with the image.
However, we expect Google to make the Android 4.2.1 factory image for Nexus 10 tablet available within the next few days, so stay tuned for more updates on the matter.
