Owners of Nexus 4 and Nexus 7 devices have been waiting for the Android 5.1 Lollipop update on their devices for over a month and the wait is finally over.
Shortly after reports of official OTA update of Android 5.1 Lollipop for Nexus 4 appeared online, Google published factory images of the software for its 2012 handsets, Nexus 4 and Nexus 7. As a result, users who are eager to get their hands on the latest software can finally download and install Android 5.1 on their devices.
Before manually updating the Nexus devices with the latest software, it is important to know how to prepare the device to avoid any errors. Firstly, users need to back up their data on the handsets as installing factory image will wipe the phone clean. Ensure ADB and Fastbook is set up correctly and the PC has all necessary drivers needed to detect the smartphone. Also, bootloader must be unlocked in order to flash the factory image.
Once your device is ready for the manual update, follow these steps to make sure the software is installed correctly, (via Google). The build number for Android 5.1 is LMY470.
