How to download and install Android Oreo

Android Oreo final release

The presentation of the final release of Android O happened during the total solar eclipse on August 21, 2017 at 2:40 PM local time, and the live stream video of the event (and the eclipse) was on Google's website. Android Oreo is now available to download and install on certain devices.

The Nexus 5X, Nexus 6P, Nexus Player, Pixel C, Pixel and Pixel XL are the first devices to get the final version of Android 8.0 Oreo over the air. Devices around the world are now getting the OTA update. You can read about all the new features in the update here.

How to install Android Oreo

You can download the newest available system images here, and then flash (install) them to your device. The following section contains the instructions from Google on how to flash a system image. For information on specific devices, see here if you need more help.

To flash a system 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.

4. 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

The target device will show you a confirmation screen. (This erases all data on the target device.)

See Unlocking the bootloader for more detailed instructions.

5. Open a terminal and navigate to the unzipped system image directory.

6. Execute the flash-all script. 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.
