How to Update OnePlus 5 and 5T to Android 9.0 Pie (Custom Firmware)

OnePlus promised Android Pie update for both 5 and 5T, but we don’t expect the official Oxygen roll out before December 2018. Meanwhile, the developers aren’t sleeping. Thanks to Men_in_black007 (the Recognized XDA contributor ), to release this ROM via the unofficial route. Now you can try out the test of the latest Android 9.0 Pie on your OnePlus 5 and 5T. In this guide, we will describe entire steps on how to install Android Pie on OnePlus 5 and 5T using TWRP Custom Recovery. If you don’t have a custom recovery installed from before, we have a guide link for it.

OnePlus 5/5T Android 9.0 Pie Update [info]

  • This Pie ROM is not an official firmware by OnePlus, but a Custom ROM which would require a Custom Recovery like TWRP to install.
  • The Android Pie ROM for OnePlus 5/5T is AOSP based, which means a naked Android without any custom modification.
  • Since this is just an initial release of Pie update, you may face some bugs on the OS. You can report to the respective developer with screenshots for your known issues.
  • This ROM doesn’t come with Google Applications. So after flashing the ROM, you need to flash the GApps package too to get the Google App access.
