Install LineageOS 15.1 on OnePlus 5T (Android 8.1)

LineageOS 15.1 on OnePlus 5T is now officially out, available for download on the xda thread as well as the official website, thanks to the developer Evisceration.  LineageOS 15.1 is based on Android 8.1 Oreo, and comes in with the stock-most experience, with just a few tweaks and options to play around with. In this guide, you will be able to learn how to Install LineageOS 15.1 on OnePlus 5T.

The OnePlus 5T boasts of some insane specifications including the all great Snapdragon 835, upto 8 gigabytes of RAM, insanely quick UFS 2.1 storage and more. While it only has the 18:9 display and a slightly different use of the second camera that’s different than the OnePlus 5, the phone has been received well by both the media and the consumers. Part of which is to be praised thanks to the great software, which is OxygenOS based on Android Oreo.

However, some people complain that OxygenOS is too heavy of a skin for their taste, and here is where the world of custom ROMs comes in. LineageOS has been around for the longest time under the nostalgic name of CyanogenMod. The ROM is based on stock Android 8.1, and has all of its design queues, bells and whistles. On top of that, users get a few remarkably useful tweaks to play around with. While there aren’t many options built into the ROM, it strikes a great balance between stability and performance.

If you have an unlocked bootloader, with a custom recovery like TWRP installed on your OnePlus 5T, then the procedure will be quick and easy. If you don’t however, we have detailed guides on the following as well. Lastly, Although OnePlus claims that the users still retain their device’s warranty, we strictly advice you not to proceed with the guide unless you are an Android enthusiast wanting the most out of your device.
