Treble is the most talked about project lately and we are already seeing some AOSP builds for the same. Moreover, a lot of manufacturers are actively supporting Project Treble and launching phones with its support. based for their devices. This includes the Google Pixel 2, Essential Phones, Huawei Mate 8, HTC U 11 Plus, and much more. Read more about the list of Project Treble supported Android phones. Here are the first Android Oreo based AOSP builds for Project Treble enabled devices.

Project Treble basically enables the user to flash a pure stock AOSP ROM called “vanilla” directly onto your Treble enabled Android device. This is helpful in upgrading your phone to the latest available Android version. Even though the idea seems like a thing of the future, the development has already started. Following you will find some AOSP firmware builds for first few devices.

The Project Treble requires a partition storage on the device which can mostly be achieved during manufacturing. Although it can be created via OTA update, it is a risk and not many manufacturers are willing to take it. This is a reason some devices like OnePlus 3/3T/5/5T, Galaxy S8/S8+, etc won’t get treble support. New devices which come with Oreo out of the box needs to be treble enabled.

Here are the supported Android devices for Project Treble AOSP builds:

  • Essential PH-1 — A/B
  • Google Pixel — A/B
  • Google Pixel XL — A/B
  • HTC U11 Plus — A/B

  • Huawei Honor 8 Pro — A-only
  • Sony Xperia XZ1 — A-only
  • Sony Xperia XZ1 Compact — A-only

Warnings and notes:

  1. Before you go, and flash the builds, the development is in progress and you may encounter some bugs at the moment. Some of the below GSI builds can be used as daily drivers.
  2. As the developer of these GSI builds says, the goal of this ROM is to provide full Treble-compatible hardware support and that’s all.
  3. If you happen to try the system images, try them at your own risk. We won’t be responsible for a bricked device. You can always restore your device to stock via factory images.
