How To Guide OnePlus 9 Pro: How to switch between Color OS and Oxygen OS without unlocking the bootloader

[mlgmxyysd]

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 Pro
Oxygen OS for OnePlus 9 Pro

i downloaded the file yesterday. to be specific, that one OnePlus 9 Pro Color OS 11.2.A.03.
Phone says it's not compatible, so would assume that this doesn't work.

thanks for your feedback

[craznazn]

Hello, I'm having trouble applying the ColorOS downgrade on Oxygen 11.2.3.3.LE15BA. I get the "Installation package does not meet the necessary requirements". I've also tried to use the Full OTA in conjunction with resetprop, and it gives the same message. Any ideas?
