We recently saw the return of the Nexus 4 Android 4.2.1 factory images and coming as we would expect given an updated release — Google has posted the Android 4.2.2 factory images. These images are available for the Nexus 10 and Nexus 7 tablets as well as the Nexus 4 and Galaxy Nexus smartphones.
Some handsets, such as the carrier specific Galaxy Nexus models and the Nexus S are still reflecting older builds. Basically, these factory images will be useful for those who have flashed a custom ROM and are now looking to get back to the original out-of-box state. Or alternatively, these will be useful for those who tried to flash a ROM and ended up with a brick.
One of the interesting takes here, some of the smartphones have several builds available. Some are going back to Android 4.0.4 and even 2.3.6, but in the case of the Nexus 4 — it is just Android 4.2.2 (JDQ39). While there are most likely some theories as to why that is, we should point out that the Nexus 10 and 7 sit in a similar position with just one version being available. Another exception is for the Wi-Fi only Nexus 7 which has 4.2.2 (JDQ39) and 4.2.1 (JZO54K) available.
Bottom line here, Google has released the Android 4.2.2 factory images for most Nexus devices which really just goes to say that you should be able to do a bit of playing with ROM’s and a bit less worrying about not being able to get back to where you began. If nothing else, we suggest downloading the factory image for your device ahead of time — just in case you need it urgently, or just in case Google happens to remove it like they did with the 4.2.1 images.
