How To Install Android Oreo Before Official Release

Android Oreo

Whenever a new smartphone OS update is announced, enthusiasts can’t wait to get their hands on the update and try it out as soon as possible, even if there are bugs in the update. So how do these people go about downloading the update and try it early? Here will help you install the Android Oreo update for your Android device before the update actually goes live for the general public.

With the official unveiling of the next OS iteration, Android Oreo will soon be available on recent Google devices. Currently, there is no fixed date on when Android Oreo will be available but the update tends to roll out in waves, starting with the latest Google devices while also keeping the region in mind as each global region gets the update at a different time.

Android Oreo Update Availability

As of right now, Google has confirmed that Pixel, Pixel XL, Pixel C, Nexus 6P, Nexus 5X and Nexus Player will receive the official Android Oreo update with the Pixel devices expected to receive it a little earlier than the Nexus ones. Some cellular operators have started shipping out over-the-air (OTA) updates to their users with Google Pixel devices while others like the Canadian based Rogers have hinted Nexus devices like Nexus 6P should receive the update next week.

Unfortunately, since OTA update delivery for Android updates also depends on the cellular network provider, some parts of the world tend to get the update weeks after official launch. On top of that, anyone without a Google device will have to wait even longer as their own manufacturer works on the “custom flavor” of Android Oreo before delivering it to their respective devices.

Because of all these caveats, a lot of Android users prefer manually installing the updates, despite some risk involved and potential data loss.

How to Install Android Oreo Update Early

Just like with every other major Android update, Google has released the developer preview build of Android 8.0 on their official web portal. Anyone can download the build of the firmware update for free and install it, if they know what they are doing. As has been mentioned earlier, there is risk involved when manually updating to Android 8.0 as not only will it wipe all data from storage but if something goes wrong, it can also brick the device and render it useless.

Before proceeding, it is best to go to Settings on your Android device and then Backup all the data using Backup & Reset. Another manual backup of the storage by connecting to a computer is also a good idea. Once backup has been done, you can proceed to updating your device to Android 8.0 Oreo.

Developer Access:

  1. To start off, you will need developer access to your Android device which is pretty easy to get. All you have to do is head to the About Phone section in settings and tap the Build Number seven times after which a message appears on screen mentioning that developer access has been enabled.
  2. When that is done, you can return to the Settings menu where a new option called Developer Options will be visible now.
  3. Open Developer Options and make sure both OEM Unlocking and USB Debugging are enabled so you can unlock the bootloader to flash the Android Oreo preview build.

Downloading the Android Oreo Factory Image:

  1. Open the Google web portal here to download the Factory Image files.
  2. Navigate to the Android Oreo section.
  3. Look for your Android device in the list and then download the corresponding factory image, which should be around 1GB in size.
  4. Download 15s ADB Installer, a light weight tool that allows you to flash the Factory Image to your Android device.
  5. Run 15s ABD Installer.
  6. A prompt will ask you to install ADB and Fastboot.
  7. Press Y for all prompts that ask to install different components
  8. Once installation has been done and Android Oreo factory image downloaded, restart your PC.
  9. Put everything inside a single folder so they can be easy to find when doing the actual installation.
  10. In order to make sure that ADB recognizes the Android update you downloaded, extract the update files to the folder where you installed ADB. By default, this should be C:\adb

Unlock Bootloader:

In the C:\adb folder, hold Shift+right click in an empty space and then click on “open command window here” after which you need to enter the following command:

fastboot flashing unlock

Flashing the Android Update:

  1. Make sure the android device is fully charged and then power it off.
  2. Now, press and hold the power and volume down button on your Android smartphone simultaneously which will take the device into Fastboot mode.
  3. Return to your PC, open up the folder where you extracted the Android Oreo Factory Image and run the file called flash-all.bat and wait until the installation is completed.

Based on the quality of the USB cable you are using to connect to your phone, the installation process can take some time, even up to 5-10 minutes.

As there is no progress bar during the installation process, make sure you don’t accidently or impatiently disconnect the phone as it can brick your device and make it useless. Just wait until you either get an error or a success message.

If everyone goes as intended, once the installation is complete your Android device should restart and after a somewhat longer boot time, take you to your new Android Oreo homescreen so you can enjoy the next Google Android firmware.
