Manually Install Android 8.1 Oreo Preview

If you cannot wait for the beta program and OTA updates, you can also manually flash the software. The first thing you need to do is installing  ADB driver on your computer as well as downloading the Android 8.1 Oreo System Image for your device.

Once done, unzip these files to a selected folder. After you have unzipped the Android Oreo system image, type cmd into the address bar on Windows, or open a terminal on Mac, Linux or Chrome OS. Reminder, if you are using a MAC, remember to make sure terminal is running inside the unzipped image folder.

If your Nexus/Pixel device is not unlocked bootloader, you need to do that first as the Android 8.1 beta can’t be installed on a locked device. Here are steps to manually flash Android 8.1 Oreo.

  1. Open a Terminal or cmd in the adb folder and enter the command below to unlock bootloader

adb reboot bootloader

For Nexus 6P or Pixel devices, you will need to type “fastboot devices” and then “fastboot flashing unlock” to unlock the bootloader

  1. In Fastboot, enter

fastboot oem unlock

Follow the on-screen instructions and wait a minute for it to unlock.

  1. Now, on Windows, double click on flash-all.bat. If you are using a Mac or other platforms, you will need to enter: sudo ./
  2. After flashing the Android 8.1 O Preview Factory Image is complete, simply unplug the cable and reboot your device.

That’s all! You only now complete the setup process and start enjoying Android 8.1 Oreo
