Download and Install Android P Custom ROM


Android P is the upcoming ninth major version of the Android operating system. It was first announced by Google on March 7, 2018, and the first developer preview was released on the same day. The second preview, considered beta quality, was released on May 8, 2018. The third preview, called Beta 2, was released on June 6, 2018. The fourth preview, called Beta 3, was released on July 2, 2018. 

Prior to the development of Project Treble, Android Beta testing was only for developers who had a Pixel or Nexus device but after the introduction of Project Treble with Android Oreo, in first of its kind, Google announced that third-party Android phone makers like Essential, Nokia, Sony, Vivo, Oppo, OnePlus and Xiaomi as a part of the Android P Beta Project. According to Google, a lot of credit goes to Project Treble for making non-pixel devices eligible for the beta program.

Android P Custom ROM

Originally, A beta preview for Android P was provided by Google for Google Pixel, Google Pixel XL, Google Pixel 2, Google Pixel 2 XL, Essential Phone, Nokia 7 Plus, Oppo R15 Pro, OnePlus 6, Sony Xperia XZ2, Vivo V9, Vivo X21UD, Vivo X21 and Xiaomi Mi MIX 2S. Though, in terms of penetration, a lot of devices are eligible for the beta update officially, then also a lot of Android users who do not own any of these eligible devices were left disappointed.

Android P will not be released until late August so before enjoying a custom ROM you need to wait for Google to share the official source code. However,  XDA developer Erfanoabdi managed to bring Android P Beta version on some Snapdragon-powered Project Treble devices. The new port is built from Google Pixel XL Android P DP3 system image.

Most of the devices listed here require you to install a ROM with unofficial Treble support before moving to this Android P beta port. This is also the case for the OnePlus 5 and OnePlus 5T which, despite having recently received official Treble support with an OxygenOS update, still require the unofficial Mokee Treble implementation.

Note that this is an unofficial port of the 3rd Developer Preview or 2nd Beta of Android P hence, you can find bugs, app crashes, performance drops, degraded camera performance, VoLTE problems and other similar issues. If you want a more stable release of Android 9.0 for your Treble-enabled device, wait for Google to release the source code next month so proper GSIs can be compiled from source.
