OnePlus 9 Series: How to switch between Color OS and Oxygen OS without unlocking the bootloader

The China variant of the OnePlus 9 series comes with Color OS instead of Hydrogen OS by default, which is not good news for geeks as Color OS has many limitations compared to Hydrogen OS. Recently, OnePlus has officially provided a way to switch between Color OS and Oxygen OS.

Please note that switching systems will clear all user data, so you better know what you're doing.

· Switch from Color OS to Oxygen OS
Download the downgrade package for the appropriate model and system and put it in the internal storage.

Installation steps: Settings - Software update - Settings (top right corner) - Select installation package - Select the previously downloaded downgrade package - Install now - Install now

If the Select installation package option is grayed out, it means that you now have a pending system update and you can choose to install or skip it.

To skip update: Settings - App management - App list - Menu (top right corner) - Show system - Software update - Storage usage - Clear data - OK - Disconnect all network connections

· Switching from Oxygen OS to Color OS
Download the downgrade package for the appropriate model and system and put it in the root directory of the internal storage.

Installation steps: Settings - System - System updates - Settings (top right corner) - Local upgrade - Select the previously downloaded downgrade package - CONFIRM

Just reboot your device after the installation is complete and have fun!

Downgrade packages:
Color OS for OnePlus 9
Color OS for OnePlus 9 Pro
Oxygen OS for OnePlus 9
Oxygen OS for OnePlus 9 Pro

FAQ

Q: Why was the IMEI changed after switching?
A: 11.2.4.4 has fixed this display bug.

Q: What is my OS version after the switch?
A: Color OS is 11.2.A.03. Oxygen OS is 11.2.2.2.LE15/25DA (India).

Q: Can I update my system normally after switching?
A: Sure.

Q: The installation package does not meet the necessary requirements, please try installing others.
A: Download the #Downgrade package instead of the full package.

Q: Unable to click on Select installation package.
A: Read the thread again carefully.

Q: How do I switch to Europe or Global OS?
A: Wait for the new version, download the #Full package and Local Update it. If you have Magisk installed, you can try to Local Update after entering the following command (need ROOT access).
resetprop ro.build.date.utc 1400000000

Q: Why do I need a downgrade package?
A: For OnePlus, a downgrade package does not necessarily mean downgrading the system. The system will not detect the version of the package, which is the only difference between a downgrade package and a full package. Also, you can use the above command to make the full package achieve the same effect.
