Google has just started rolling out the latest Android 5.1.1 Lollipop update via factory images for Nexus 7 (2012 Wi-Fi), Nexus 7 (2013 Wi-Fi), and Nexus 10, which bumps the build number to LMY47V.

The new Android 5.1.1 build LMY47V can be flashed only with the unlocked bootloader on the Nexus device, and those who missed the OTA update notification or cannot wait for the official OTA release in their country can follow our step-by-step guide (below) to install the official factory image for Android 5.1.1 on your Nexus device.

Users are advised to perform a full data wipe, especially if they are installing the Android 5.1.1 stock update on a custom ROM.

Note: All Nexus devices running Android 5.1 Lollipop (stock and custom ROM) can be upgraded to the latest build of Lollipop (LMY47V) via the official factory image.

IBTimes UK reminds readers that it will not be held liable for any damage to device during or after firmware installation. Users are advised to proceed at their own risk.


  • The instructions given in this guide are meant for the Nexus 7 2012 (Wi-Fi), Nexus 7 2013 (Wi-Fi) and Nexus 10 models only. Verify device model number by navigating to Settings > About Phone as installing this firmware on incorrect variants might brick the device.
  • Ensure the phone has at least 80% battery charge to prevent unexpected device shutdown (due to battery drain) while installing the ROM.
  • Back up data and settings using a recommended custom recovery tool, like ClockworkMod (CWM) or TWRP, as it creates a complete image of the existing phone setup. In Recovery, choose Backup and Restore and tap Backup.
  • Verify correct USB drivers for the phone are installed on the computer (download Nexus 7 USB drivers).
  • Enable USB Debugging mode via Settings > Developer Options Note: If Developer Options is not visible then you need to enable it as follows:
  • Go to Settings > About Phone.
  • Scroll down to the bottom and select Build Number.
  • Then tap build number seven times to unlock the Developer Options under Settings and then enable USB Debugging mode.
  • Ensure that the device is rooted with CWM or TWRP recovery installed and its bootloader is unlocked.
