Nexus 5 and Nexus 7 (2013) Receive Android L Developer Preview via Factory Image

Nexus 5 and Nexus 7 (2013) users are in for a pleasant treat, as Google has just rolled out its futuristic Android L update to live up to its promise at Google I/O 2014.

The L update brings a new lease of life for Android geeks and developers alike who are yearning for new features, looks and a refreshingly new user interface (UI), since Google's last refresh in Android 3.0 Honeycomb.

Steps for installing Android L Developer Preview via Factory Image on Nexus 5 and Nexus 7 2013

Step 1: Download the required factory image and ADB/fastboot files for your device and ensure the downloaded firmware build number corresponds to LPV79.

Step 2: Extract the ADB and fastboot files to a desired folder on your computer, and install USB drivers for the device on computer if necessary.

Step 3: Now extract the factory image file you downloaded to the same folder where you extracted ADB and Fastboot files.

Step 4: Once the factory image file is extracted, you will see a file containing the codename of your device along with two files named "flash-all" but with different extensions. Besides, you will see a bootloader image file.

Step 5: Ensure that all the extracted files of the factory image are in same folder as ADB and fastboot files. This is to avoid file not found error.

Step 6: Boot your Nexus 5 or Nexus 7 2013 into fastboot mode as follows:

  • Turn off the device.
  • Press and hold Volume Up, Volume Down and Power buttons on your phone until the bootloader screen or fastboot mode appears on screen.
  • Then release all three buttons together to boot into fastboot mode.

Step 7: Connect the Nexus device to your computer and ensure the device is recognised in device manager.

Step 8: Double-click on flash-all.bat on Windows computer or tap on flash-all.sh on Mac or Linux computer to begin flashing the new firmware.

Step 9: Wait until the flashing process completes and then reboot the device.

Note: The first boot may take longer than expected, as the device rebuilds the cache files for first use after installing the update. So, do not interrupt the process and leave the computer alone for a few minutes after the installation.
