Finally, Android O is available for download and yes, you can install it on your Android Device. Well, official release date for the final version is yet unknown. As it is in beta version it is not safe for daily use because it is unstable yet. Android O has number of eye-catching features includes number of performance and improved battery life.

To install and use Android O, you can either flash the device with Android O image file or enroll in Android Beta Program. We will explore both methods.


Installing Android O by flash

Initially, you will require the relevant image file. Grab it from here. For more on device specific image, explore from here.

Below is the specific guide from Google to flash (install) a image.

  1. Download the appropriate system image for your device below, then unzip it to a safe directory.
  2. Connect your device to your computer over USB.
  3. Start the device in fastboot mode with one of the following methods:
    • Using the adb tool: With the device powered on, execute:
adb reboot bootloader
  • Using a key combo: Turn the device off, then turn it on and immediately hold down the relevant key combination for your device.
  1. If necessary, unlock the device’s bootloader using one of the following methods:
    • If you are updating a Nexus 5X or Nexus 6P device using the hammerhead or angler builds, update your fastboot tool to the latest available version (>=23.0.1), and then run this command:
fastboot flashing unlock
  • If you are updating an older device, run this command:
fastboot oem unlock
  1. The target device will show you a confirmation screen. (This erases all data on the target device.)
  2. See Unlocking the bootloader for more detailed instructions.
  3. Open a terminal and navigate to the unzipped system image directory.
  4. Execute the flash-all This script installs the necessary bootloader, baseband firmware(s), and operating system.

Once the script finishes, your device reboots. You should now lock the bootloader for security:

  1. Start the device in fastboot mode again, as described above.
  2. Execute:
fastboot flashing lock

or, for older devices, run:

fastboot oem lock

Locking bootloader will wipe the data on some devices. After locking the bootloader, if you want to flash the device again, you must run fastboot oem unlock again, which will wipe the data.
