Download Android P 9.0 GSI for Project Treble Install Android P Generic System Image

Update: The latest Android P Developer Preview 5 is now available for download. So is the Android P GSI now available for download for all the Project Treble enabled devices.

Google has been reportedly testing the Android P Generic System Image for its new Project Treble. Under this project, all the new phones shipping with Android 8.0 Oreo or later must support Treble. Google also releases the AOSP GSI for all Project Treble supported devices from various smartphone manufacturers. This means, most of the new 2018 Android device can now directly update to the latest Android OS version by installing a Generic AOSP build (or GSI). We already have the AOSP, Lineage OS, and Resurrection Remix GSI available based on 8.1 Oreo. Now, we have the first unofficial build of Android P 9.0 GSI available for all Android devices.

You can simply download the Android P GSI and flash it using a custom TWRP recovery or Fastboot mode. Meaning, you can upgrade any phone with Treble support to Android P. As this is the first Android P GSI build, it could be quite unstable for some devices. It is purely experimental build but with a lot of potential. With further support, we expect many bug fixes and support for more phones. So stay tuned and keep visiting for more updates.

Moreover, the GSI builds listed below currently only support Qualcomm SOC (Snapdragon processors). So although Galaxy S9 has Treble support, the ROM may crash a lot as the device possess a Exynos possessor.
