How to Install Android Lollipop on Phone and Tablet?

I repeat, your phone will be reset to its original factory settings after this step. So please backup your Android data before doing it.

Steps to Install Android 5.0 Lollipop on Nexus Phone or Tablet

Step 1. Download and Install Drivers on Your Computer

Step 2. Download and Unzip Factory Image on Your Device

Now you'll need to be able to flash the new Android 5.0.2 image on your device. But obviously you cannot do this without going into the developer options menu and enabling USB Debugging.
- For Android 2.3 or earlier: Enter "Settings" < Click "Applications" < Click "Development" < Check "USB debugging".
- For Android 3.0 to 4.1: Enter "Settings" < Click "Developer options" < Check "USB debugging".
- For Android 4.2 or newer: Enter "Settings" < Click "About Phone" < Tap "Build number" for several times until getting a note "You are under developer mode" < Back to "Settings" < Click "Developer options" < Check "USB debugging".

After downloading the final Android 5.0.2 Lollipop System Images on your device, you can unzip the file to a folder. Then, you can find the folder and type "cmd" into the address bar (Windows). For Mac, Linux or Chrome OS users, you can open Terminal and change the folder.

Step 3. Finish the Installation

Open a Terminal in the adb folder and type "adb reboot bootloader" then hit enter. Then, you can type "fastboot oem unlock" in Fastboot and hit enter again. Now the program will start to erase data on your Android phone or tablet. Now you can open the folder with the unzipped Image file and type cmd into the address bar. Now go to "System Preferences" > "Keyboard" > "Shortcuts" > "Services" > "New Terminal at Folder" in the settings menu. After that, you can right-click a folder and you can open Terminal to copy and paste "flash-all.bat" to install the update to your device.

Once the files begin to install, your Nexus device may reboot. An Android figure will appear, followed by an Android logo. If the logo screen remains for a long time, just wait patiently. Be warned. The wait time could be as long as ten minutes. Once prompted to complete setup you can unplug your device.
