In this guide, we will show you the steps to install various custom ROMs based on Android 14 onto your OnePlus 8T. When it comes to custom development, then there’s no denying the fact that the offerings from OnePlus have always been among the most active players in custom development. In this regard, it’s been close to four years since the T series of the eighth iteration made its way, but the device is going pretty strong even to this date.

There’s no better way to cement this statement than by stating the fact that the device has just been blessed with the latest fourteenth iteration of the OS. Along with that, there are a slew of custom ROMs housing the Android 14 waiting to make a permanent abode on your device as well. So now is the perfect chance to break free from the shackles of the bloated “ColorOS” and welcome a clean AOSP experience with a few additional goodies. And in this guide, we will show you how to do just that. Follow along.

How to Install Android 14 Custom ROMs on OnePlus 8T

Before starting with the process, make sure to take a complete device backup beforehand. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps. Make sure you are on the latest OxygenOS 13 Android 13 firmware before flashing this ROM.

STEP 1: Install Android SDK

First and foremost, you will have to install the Android SDK Platform Tools on your PC. This is the official ADB and Fastboot binary provided by Google and is the only recommended one. So download it and then extract it to any convenient location on your PC. Doing so will give you the platform-tools folder, which will be used throughout this guide.

STEP 2: Enable USB Debugging and OEM Unlocking

Next up, you will have to enable USB Debugging and OEM Unlocking on your device. The former will make your device recognizable by the PC in ADB mode. This will then allow you to boot your device to Fastboot Mode. On the other hand, OEM Unlocking is required to carry out the bootloader unlocking process.

So head over to Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging and OEM Unlocking.

STEP 3: Unlock Bootloader on OnePlus 8T

Next up, you will also have to unlock the device’s bootloader. Do keep in mind that doing so will wipe off all the data from your device and could nullify its warranty as well. So if that’s all well and good, then please refer to our detailed guide on How To Unlock Bootloader on OnePlus 8/8 Pro/8T
