Download/Install Lineage OS 18.1 For OnePlus 8T (Android 11)

After OnePlus 8, now its successor the OnePlus 8T has received an unofficial build of Lineage OS 18.1 based on Android 11. You can follow our guide to manually download and install the ROM on your device.

As mentioned, among all the aftermarket firmware, Lineage OS is the best one when it comes to performance, stability, and fully-featured Custom ROM. Thanks to Xda developer/uploader LuK1337, and the Lineage OS Team for this latest ROM.

As I mentioned it above, OnePlus 8T was launched as a successor to the OnePlus 8 in the same year. The device has already received the Android 11 update from the company. When Oxygen OS is one of the best Android skin out there, it still lacks in Customization compared to Custom ROMs. If you love to MOD your device, then Lineage OS 18.1 might be useful for you.

LineageOS is a free, community-built, aftermarket firmware distribution of Android 11, which is designed to increase performance and reliability over stock Android for your device.

Download/Install Lineage OS 18.1 For OnePlus 8T (Android 11)

The installation is pretty simple and easy. If you have installed any custom ROM before then you will have no issue flashing the ROM as the process is exactly the same. But before proceeding to the installation let me clear that this build is in the very early stage which means there will be bugs and many functions may not work properly. So, we do recommend not to flash the ROM on your primary device.


  • Enable USB Debugging on your OnePlus 8T. Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging.
  • Also, enable the OEM Unlock from the Developer Options.

  • Make sure the bootloader on your device is unlocked and your device is rooted and you have a custom recovery installed.
  • Make sure your device has more than 50% battery.
  • Make sure you have taken a backup of your important data. Now proceed to install Lineage OS 18.1 ROM (Android 11) on your OnePlus 8T device.
  • Download and install the Android SDK Platform Tool on your PC. This will provide you with the necessary binary files.
  • Also, download and install the OnePlus USB Drivers onto your PC

Disclaimer is not responsible for any damage happened to your device(s) while following this guide, proceed at your own risk.

Flashing Steps: Lineage OS 18.1

  • First, download the ROM files from the above link and extract them to the ADB folder (It will be created once you install SDK platforms tools)
  • Connect your device to the PC via USB cable
  • Open command window (prompt) on the same folder (Type cmd on the search bar) or Just right click on the mouse and click Open command window here

Open cmd from here

  • Now flash the ROM by issuing the following commands
fastboot -w (this will wipe your data)

fastboot flash recovery recovery.img

fastboot reboot fastboot

fastboot erase scratch (this is safe to fail as scratch is only created upon adb remount)

fastboot flash boot boot.img

fastboot flash dtbo dtbo.img

fastboot flash system system.img

fastboot flash system_ext system_ext.img

fastboot flash product product.img

fastboot flash vbmeta vbmeta.img

fastboot flash vbmeta_system vbmeta_system.img

fastboot reboot
  • Once the installation is completed, reboot your device. Done!!

Once the flashing process is completed, reboot your OnePlus 8T and you will be booted into Lineage OS 18.1 ROM Based on Android 11. If you have any doubts regarding this process, feel free to comment below.
