Instructions to Install Android 8.1 Oreo on Pixel and Nexus Devices
The fastest way to install the new update is by updating over-the-air. For that, you shall go to ‘Settings’ » ‘System’ » ‘System update’ and check for the notification manually.
The update might take some time before it reaches out to your specific device. However, if you’re not patient enough like me, you can follow the instructions below to install Android 8.1 Oreo right now.
- Download Android 8.1 Oreo Factory Image for your device.
- Use 7ZIP or similar software to extract the factory image (e.g. angler-opm1.171019.011-factory-39448337.zip).
- Copy the extracted files to the “C:\adb” folder where all the ADB and Fastboot binaries are present.
- Now, edit the “flash-all.bat” file using Notepad++. For macOS/Linux, edit the “flash-all.sh” file using BBEdit or similar software.
- Find the line starting with “fastboot -w update”. Example:
fastboot -w update image-angler-opm1.171019.011.zip
- Remove the “-w” flag from the line and save the file.
- Now, boot your Pixel/Nexus device into Fastboot mode:
- Shut down the phone completely.
- Press and hold the Volume Down + Power button altogether until you see the Bootloader/Fastboot screen.
- Connect your device to the PC via the USB cable.
- Finally, double-click on the “flash-all.bat” file to install Android 8.1 Oreo.
- On Linux/macOS, open the Terminal and execute the following command:
./flash-all.sh
- The flashing process shall begin and the new Oreo 8.1 update will be installed on your device.
- When the process is complete, your device will reboot automatically.
Once your phone boots, follow the on-screen instructions and set up the device. The new update also allows you to restore your backed-up content even after you have finished the initial setup. So take its advantage.
That was how you can manually install Android 8.1 Oreo by flashing the factory image. If you have any queries, simply contact us via the comments.

I’m confused. Under the prerequisites you state, “Flashing factory images require your phone’s bootloader to be unlocked.” But from what I gather, unlocking my device (a Nexus 6P) will wipe all the data off it. So, I will then need to reinstall all the apps and reload all the data? I thought there was a way to do this that mimicked an OTA update. Or – can I do these steps without unlocking first?
Hey Jeffrey. Let me lay down the facts in form of pointers.
1) Flashing anything using Fastboot like Factory Image or individual partitions, requires an unlocked bootloader.
2) Yes, unlocking/locking back the bootloader will perform a full wipe, which includes the internal storage too.
3) And yes, there’s another way to perform this update without having to unlock.
That is to use “Full OTA Images” instead of “Factory Images”. Unlike factory images, full OTA does not need fastboot. Rather, it can easily be sideloaded using the stock recovery.
Recently, the January update (Android 8.1 Oreo) was announced. We have covered the tutorial for that too and it includes the Full OTA flashing (Method 2). You can check out the guide right here: https://www.thecustomdroid.com/install-january-2018-security-patch-google-pixel-nexus/
Is there a way to install 8.1 on a rooted Nexus 6p without losing root?
Quite easy. All you have to do is flash TWRP and just root it by flashing SuperSU/Magisk. Make sure that you do it before the first boot. Or, your internal storage will be encrypted (If it was decrypted earlier).
