Procedure to Update Nexus 5 or Nexus 7 with Android L Preview Firmware:

First up, you need to download the below mentioned files depending upon the device on which the update needs to be applied.

The ADB file has to be first extracted and installed, and it would take care of everything from installing the ADB drivers and phone drivers. Once that is done, go to the folder where you downloaded the image file for Android L for your Android device, i.e. either Nexus 5 or Nexus 7. It takes no more than a minute to install it and proceed to the next step.

Extract the Image files to a folder which you can access easily. Now, based on the computer you are using, follow the instructions below for Windows and Mac OS.

For Windows Users

Navigate to the folder where you extracted the files of Android L image, and there right click on the empty folder area to see the commands. Click on “Open command window here” and then the command window would open for that particular folder.

Then, you will have to enter a few commands, in the following manner for the Android L image to be installed on your Nexus device.

adb devices

The devices which are connected would be listed, and you need to have the device unlocked or the installation would not happen.

fastboot devices

adb reboot bootloader

fastboot devices

flash-all.bat

The final command of flash-all.bat would confirm and a set of steps would occur in the command window, and the further process of installation would be done on your Nexus device, and after the reboot, you would be seeing the new Android version, i.e. Android L installed on your device.

The other steps are similar to that for the Windows users, given above.

    Under the Pre Requisites you mentioned some apps from which you can back up data on your phone! So I just want you to make a correction that Nexus 5 and Nexus 7 does not have an external SD card. So I think it is inappropriate so kindly make a change!
    Thanks
