Roll Back OnePlus Phones to OxygenOS 12 from OxygenOS 13 [Downgrade]

If you own a OnePlus phone and have recently updated to Android 13 based OxygenOS 13, but are experiencing issues or simply prefer the older OxygenOS 12 (Android 12) version, it is possible to roll back or downgrade your phone’s operating system. However, it is important to note that downgrading carries certain risks and it is always recommended to back up your important data before proceeding.

To begin the downgrade process, you will need to download the appropriate zip file for your specific device and region from a reliable source. It is also recommended to ensure that your device is charged at least 50% to prevent any interruptions during the process.

Steps to Downgrade to OxygenOS 12 from OxygenOS 13

Once you have the necessary zip file (here in this case OxygenOS 12 Firmware file for the device), move it to your phone’s internal storage and follow these steps:

1. Go to Settings and select the “About device” option.
2. Click on the “Version” option and then tap the “Build number” seven times.
3. Enter the password when prompted and this will take you into developer mode.
4. Go back to Settings and select the “About device” option again.
5. Click on the “Up to date” option and then tap the top right button to find the “Local install” option.
6. Select the specific rollback package and extract it.

It is important to note that after the downgrade, you should click on the “reboot” option to apply the update in the system and complete the process successfully. Downgrading to OxygenOS 12 from OxygenOS 13 on your OnePlus phone is a relatively straightforward process, but it is always important to exercise caution and make sure to back up your data before proceeding.
