0

The Android Pie for OnePlus 3 and 3T is in works for past few months. Finally, we have got our hands on the official and stable Android Pie firmware for OnePlus 3/3T. It is based on OxygenOS 9.0.2. Therefore, it comes with all the goodies of new Android version. This time, there are no bugs and therefore it is bound to run smoothly.

The only downside to this good news is that it is an incremental update. OnePlus is pushing the update to few selected devices at any given time. It could be weeks before it reaches your region. Hence, follow the guide below to download OnePlus 3/3T OxygenOS 9.0.2 Android Pie 9.0 official firmware. It is a stable release and extracted directly from the servers. Moreover, it is not an incremental update zip but a full OnePlus 3/3T Android Pie firmware zip. It works the same on both rooted and non-rooted devices.

The incremental update zips do not work with rooted phones. Since the system is modified, the update process may soft-brick the phone. On the other hand, non-rooted phones work with incremental update zips just fine. Therefore, we have got the full flashable zip of OxygenOS 9.0.2 for OnePlus 3/3T. The easiest way to judge if a file is either incremental update or full firmware is to check size. If the zip is over 1GB in size, then it is full update file and it works on both rooted and non-rooted phones. 

Requirements

  • Charge your phone over 50%.
  • Make a backup of all data on internal storage. The update may wipe the phone clean.
