A day after T-Mobile announced they were releasing security updates for the Nexus devices on their network, Google has now published the Factory Images for the Nexus 4, Nexus 5, Nexus 6, Nexus 7 (2013) Wi-Fi and Nexus 9 on the Android developer site. The images are available for anyone to download and install assuming they have root access to their device and are familiar with the procedure. Those who had rather not go through the process can simply wait and the update will be coming to the devices in the coming days via OTA. The build number, for those keeping score at home, is LMY48M and is an update to Android Lollipop as you would expect.
The updates are a part of the monthly security updates that Google announced last month with this one serving as the September update. The monthly security updates started after the Stagefright exploit scare. As far as the contents of this new release, it is fundamentally security focused with a few minor bug fixes but what exactly is addressed has not been stated.
I’ll remind readers that you do not necessarily have to download these – updates will come to your Nexus devices via OTA in a few days. However, if you really want to have the latest build right this minute, you can go through the install process which Google outlines in great detail on the Factory Images page.
Equally, if you do this, make sure you have the correct build for your devices. Generally speaking you will need the images that are build LMY48M. However, if you are a Nexus 6 owner on T-Mobile then you will need to download version LYZ28J. If you are using a Nexus 6 and on Project Fi, you will need to get version LVY48E.
