1. Boot your Nexus device into fastboot mode. You do this by turning it off and holding down the volume up + volume down keys and then pressing power. That should work for all modern Nexus devices but if not, you may need to Google Search how to do it on yours.
2. On your computer, use 7zip to extract the .tgz file you downloaded from the Android Developer website. Use 7zip a second time to extract the .tar file you extracted from the .tgz. When you’re done, you should have a folder with several files in it.
3. Copy all of these files and paste them in the platform-tools folder in the Android SDK on your computer. If you followed the above tutorial, this should be under the C drive, then under Program Files (x86) on Windows. Linux users, you know where you put it.
4. If you have not already done so, connect your Nexus device to your computer. ADB and Fastboot commands should already work at this point if you’ve been following along.
5. There are two flash-all files. If you’re in Windows, you’ll want to double click the one that has the gear logo and says “Windows Batch File” on the right. If you’re on Linux, you’ll want to double click the flash-all.sh.
6. At this point a box should pop up and you should see the installation taking place. While this is going on, do not unplug your device for any reason. Let it do its thing.
7. Once the installation process as finished, your device will automatically reboot and you should see the official Android Lollipop boot animation start up. You can now safely disconnect your device from your computer. Congrats, you now have Lollipop!
