- Connect your device to your computer over USB.
- Start the device in fastboot mode.
- To open fastboot - hold the volume up, volume down and power buttons while powering on the device.
- To unlock device bootloader - Type in command - fastboot oem unlock
- Open a command terminal and navigate to the unzipped system image directory.
- Execute flash-all.bat, which was a part of the unzipped image file. This script installs the necessary bootloader, baseband firmware(s), and operating system. For this to work, you need to have added the folder where ADB and Fastboot are installed to the system's path as described in step 2.
- When this is done, Google recommends that you lock the bootloader for security. You can do that by booting the device in fastboot mode while still connected via USB, and using the command terminal to execute: fastboot oem lock.
