Official LineageOS 17.1 based on Android 10 was released earlier this year for a handful of smartphones, but over the past few months, the build roster has grown to include many more devices. For those of you who still feel left out, there are plenty of unofficial builds floating around on our forums as well.
These unofficial builds range from completely broken to surprisingly stable, and they’re undoubtedly a good way to test the custom ROM weeks or months before the build is stable enough to be made official. Now, unofficial LineageOS 18.0 custom ROMs based on Android 11 have appeared on our forums for the OnePlus 8T and the OnePlus 8 Pro.
Although both smartphones have official Android 11 releases available for them, the OxygenOS 11 skin can’t be said to be stock Android-like any more. The OnePlus 8 Pro received its stable Android 11 update back in October, while the OnePlus 8T launched in the same month with Android 11 out of the box. In fact, OnePlus published the updated kernel source code for the 8 series in September, subsequently resulting in official alpha builds of Paranoid Android “Ruby” being made for it. The company also released the kernel source code for the OnePlus 8T, which is how aftermarket developers on our forums are able to cook custom ROMs for this relatively new device.
Now, XDA Recognized Developer LuK1337 has independently ported Android 11-based LineageOS 18.0 for both devices.
Installation of the custom ROM is slightly complicated, as a compatible custom recovery solution for these devices isn’t available at this moment. We advise you to read the forum threads carefully before attempting the flashing process. The developer will also share updates on the aforementioned threads, so subscribe to the post(s) if you’re hoping to see new builds for your model.
