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.

Pre-requisites

  • 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.
