How to Convert OnePlus 12 from ColorOS to OxygenOS

This guide will show you the steps to convert your OnePlus 12 from ColorOS 14 to OxygenOS 14. The newest addition to the OnePlus family beholds quite a power-packed specs sheet. With the powerful Snapdragon 8 Gen 3 chipset, LTPO AMOLED display with 120 Hz refresh rate, and an impressive Hasselblad camera setup, there’s a lot to look forward to. If we talk about the software, then the global variant has the OxygenOS 14 whereas in China you’ll get the ColorOS 14.

While both of them are based on the latest iteration of the OS, however, there are a few noticeable differences between the two. The major issue with ColorOS to this date is the fact that it has quite a few bloatware preinstalled. Moreover, even the UI/UX is not at par with its global counterpart. If you also echo this sentiment, then you’ll be glad to know that you can now convert your OnePlus 12 from ColorOS 14 to OxygenOS 14. So without further ado, let’s get started.

How to Convert OnePlus 12 from ColorOS to OxygenOS

The below process will wipe off all the data from your device, so please take a complete device backup beforehand.

Moreover, make sure to backup the persist [highly re and ocdm [optional] partitions beforehand.

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 to convert OnePlus 12 from ColorOS 14 to OxygenOS 14.

STEP 2: Enable USB Debugging and OEM Unlocking

Next up, you will also 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.

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 12

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 12.

Fix OnePlus 12 Fingerprint not working on OxygenOS 14

In case the fingerprint is not working, then it is due to the persist partition getting corrupted. So in that case, you should restore the backup that you had earlier taken. However, if for some reason, you didn’t take the backup, then there exists a nifty yet risky workaround that might help you rectify this issue.

According to the initial findings, flashing the OnePlus 11 persist file from the same model onto your OnePlus 12 PJD110 will fix the persist/fingerprint issue. So download it from here and then flash it onto your device [Credits: XDA Senior Member _MartyMan_]. However, do note that this file will only work on the PJD110 variant of the OnePlus 12.
