Unofficial update

The above section of this article was all about the official updates for the OnePlus 6 from the OEM. Here, we will talk about the custom ROMs based on Android 9 that have been compiled from AOSP and are compatible with the OnePlus 6.

Because the Android Pie update is now available from the OnePlus 6 themselves, it doesn’t make much sense to install an unofficial update via AOSP ROM, especially given the ROM’s development stage. However, with time, the Android 9 ROMs would get better, and may extra features and customization that would make them a better choice for the enthusiasts.

How to install

Before you go on to install the ROM based on Android 9 for your OnePlus 6, be sure to read the known issues with the current version of the ROM at the development page linked here. If that’s okay with you, then go on to install the ROM using the guide right below.
  1. Make sure you have Android 8.0 Oreo OS installed. (It’s quite old now, so you must already have it easily without a doubt.)
    → Find all latest OnePlus 6 updates here. [Firmware here]
  2. Make sure you have the latest TWRP recovery installed. Find the guide to install TWRP on OnePlus 6 here.
  3. Download the latest Android 9 ROM and Gapps files from above. (The ROM comes in .XZ format, while Gapps comes in .ZIP format.)
  4. Extract the ROM file in .ZX format to get the larger ROM file (system GSI) in .IMG format. (You can use a free software like 7-zip for this on your PC.)
  5. Take the appropriate backup of your device as this will need a factory reset, which would delete everything on the device.
  6. Once the above is done, let’s install the unofficial update in Android 9 AOSP ROM on your OnePlus 6 now. Transfer the ROM (.IMG) and Gapps (ZIP) files to your OnePlus 6.
    → Be sure to transfer the extracted .IMG file of the ROM, not the downloaded file.
  7. Reboot into recovery mode to access TWRP. For this:
    1. Power off the device.
    2. Press and hold power and volume down buttons together for a few seconds until you see the OnePlus logo on the screen. You will see the TWRP soon.
  8. [Careful!] Perform a factory reset. In TWRP, tap the Wipe button, and then perform the swipe action to confirm the factory reset.
  9. On TWRP main screen, tap on Mount, and then make sure System is selected.
  10. Install the Android 9 Pie ROM on your OnePlus 6.
    1. Go back to home screen of TWRP.
    2. Tap on the Install button.
    3. Tap on the Install image button.
    4. Now select the System Image file you transferred earlier.
    5. Select System Image option.
    6. Now Swipe at the bottom to confirm the installation.
  11. Install the Gapps file. Go the home screen of TWRP, and then tap on Install, select the Gapps file you transferred above, and then confirm the installation by swiping at the bottom of the screen.
  12. Tap on Reboot system button after installing the Gapps file to restart the device.

That’s all. Your OnePlus 6 will boot with the unofficial Android 9 Pie update now.
