Google has released factory images of Android 5.1.1 Lollipop for Nexus 4, Nexus 5, Nexus 7 2012 (3G), and Nexus 7 2013 (LTE) devices. The OTA update should also start to roll out for these devices now.
Previously, Google had released factory images of Android 5.1.1 for Nexus 7 (Wi-Fi), Nexus 7 2013 (Wi-Fi) and Nexus 10 devices only.
Also, after shipping the Android 5.1.1 Lollipop OTA update to Nexus 10 at the start of this month, Google had also pushed the OTA update to Nexus 7 2012 (Wi-Fi) tablet devices a week later. We received the update in India on May 6 and it weighs 9.6MB in size.
The Android 5.1.1 Lollipop (build number LMY47V) for Nexus 7 2012 (Wi-Fi) is just a minor update from Android 5.1 (build number LMY47D), which only “improves performance and stability and fixes bugs”, notes Google. It doesn’t add any new features like the Android 5.1 update from Android 5.0.
If your device hasn’t received the OTA update as yet and you don’t want to wait for it either, then the factory images can be downloaded from Google’s Developers website here.
