There is no option called installation package in color os settings how to switch to oxygen os please helpThe 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

I don’t have enough GDrive capacity, so I am uploading it to mega & androidfilehost. After uploading, the original message will be edited without notice.Can you please reupload the Color OS Downgrade package for OnePlus 9 Pro to Google Drive or MEGA for me.
