Google will release the final build of Android L by the end of this year, most probably with the launch of a new Nexus phone.

The Android L dev preview has only released for the Nexus 5 and Nexus 7 2013. Other Nexus devices won’t be getting the Android L as dev release, but there’s hardly anything worry about since we know it’ll only take a couple of days (maybe less) for developers to port Android L dev release to other Nexus 4 and other Nexus devices.

It’s mostly neat, flat and uses soothing colors, plus most importantly, the material design animates every action on the phone.

NOTE: Your phone will be completely wiped (formatted). If you’ve any important data like photos, music or any other file, make sure to backup it up first or else don’t follow the instructions below.

  1. Download the necessary files for your device and cross verify them for the build number. It should be LPV79.
  2. Extract the ADB+Fastboot files to a folder on your computer (avoid extracting to your desktop, there might be problem when you have a user name which has space in between like xxx yyy ) and install the USB drivers in case you are on Windows PC.
  3. Extract the Factory image you downloaded to the same folder where you extracted ADB+Fastboot files, the factory image will give you a file containing the codename of your device,  two files with the name flash-all but with different extensions, and a bootloader image file.
  4. Make sure all the extracted contents of the factory image are in the same folder as the ADB and Fastboot files, otherwise you will get a file not found error.
  5. Put your Nexus 7 2013 in fastboot mode:
    1. First switch off your phone
    2. Press and keep holding the “Volume UP + Volume Down + Power” buttons together until you see the bootloader screen (aka Fastboot mode)
  6. Connect your Nexus 7 2013 to your PC and make sure the device shows up in device manager.
