Before we proceed, you should know that if any step fails to produce the supposed result, (there could be plenty of reasons, including compatibility issue, non-functional USB data cable, or even power failure), your device could get irreparably damaged. At this point, you should be well aware of the fact that by tinkering with bootloader and other files, you re treading your device into no-warranty zone.
In order to install the factory image on your Nexus device, you would need to unlock the bootloader. For that there are plenty of free tools readily available on the web. We would advise you to pick Nexus Root Toolkit, as it is among the most reliable tools out there. Alternatively, you can also go with Eclipse ADT Bundle tool from Google. It works with Windows as well as OS X and several Linux-based operating systems.
Once you have installed the Nexus Root Toolkit on your computer, you will need to select your phone and provide the current build number. You can find it from the Settings -> About phone -> Build number. You will also need to enable the USB debugging option from your phone. For that, go to the Settings -> About phone, and tap on the Build Number seven times. You will see a notification that you ve become a developer. After that, go to the Developer mode option, and enable USB debugging. You will be asked for a confirmation, make sure you allow it.
At this point, your computer and mobile device will start interacting with each other (recognize their co existence), however, for many, you may need additional drivers to establish the connection between the two devices. Good news is that the Nexus Root Toolkit will walk you through all the steps if you click on the Full Driver Installation Guide button. You need to follow steps one through four. If the application asks you to restart your computer, please kindly follow its advice.
Once those steps have been taken care of, you need to unlock your bootloader. For that, click on the unlock button in the Nexus Root Toolkit, and positively respond to all the further prompts. Your device may reboot a couple of times. After that, you are required to click into the settings menu. You will have to again click on the Build number to activate the Developer Mode and again select the USB debugging.
The next step is to get the factory image of Android 5.0 Lollipop for your device. Google has published the download links for the new operating system on its developer portal. Make sure to download the right image for your device. Also, there will be a MD5 checksum written below the download link, copy the text. On the developer portal you will find the image for many other Nexus devices as well.
Once done, check the Nexus Root Toolkit, and click on the Flash Stock + Unroot button. You will be asked to locate the factory image file you just downloaded. Select it, and paste the MD5 checksum number that you had previously copied (or go back to the portal and copy the text and paste it now).
Now sit patiently, and let the program do its thing. The phone will restart once again and you should see the Android 5.0 Lollipop on it.
