Excellent news for unlocked Galaxy Nexus and Nexus 7 owners like myself who enjoy the pleasures of fiddling with those respective devices. The Google Development team has officially released the official Android 4.1.2 build JZO54K factory images for the unlocked Galaxy Nexus (“takju”) and the Nexus 7, respectively.
Amid over the air Android 4.4 updates to Google’s Nexus devices, Google has posted the factory images for both the Nexus 4 and the Nexus 7 (2012 and 2013). Users can use these files to return their devices to stock settings on Android 4.4, essentially giving their phone or tablet a clean start.
Google posted the 4.1.2 factory images for the “Yakju” Galaxy Nexus as well as the international versions of the Nexus S (i9020t and i9023). They also offered the Ice Cream Sandwich 4.0.4 factory image for the Nexus Q.
The best part about owning a Nexus device is the almost immediate ability to upgrade to a new version of Android when it’s announced. Shortly after announcing Android 4.3, Google has put up factory images of the software for Nexus users to download and install.
Aside from the occasional legal quirks and roadblocks, owning a Nexus device is great because you’ll always have access to factory images of your device in case you ever need to completely undo any customization or just want to start from scratch.
Some hawk-eyed hackers noticed something strange this morning: the factory images for the Nexus 4 seem to have disappeared from Google’s developer site. A factory image is a file that allows you to restore your device completely to stock in case something goes wrong while hacking and tinkering with your device.
With the Takju variant of the Samsung Galaxy Nexus received Android 4.2 last week, it’s now the Yakju’s turn. To be specific, this 4.2 update is for the international version of the Galaxy Nexus not purchased in the Play Store and you should be running build JZO54K as a prerequisite before updating.
As expected, Google just posted the factory images and binaries for Android 4.2.1 (JOP40D) for the family of Nexus devices. For the Nexus 10, the factory image is still at JOP40C due to an issue. These files allow you to restore any of these Nexus devices to stock if you ever get into trouble, so download them now and keep them in a safe place.
