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

[rdaltonjay]

what country are you from? seems a common problem with oneplus 9 series color os cn version when converting to oxygen os. maybe its a wrong move for oneplus to use oppo's os.. it would be better if they stick with hydrogen for the cn versions.. older series doesnt experience such error.. you have the nvbackupui warning too?

I'm from the Philippines. Yes, I had the nvbackupui warning too. I'm just wondering if the India version can be converted to Global version. Seeing the other threads EU and NA are the Global versions?

It's not a deal breaker for me since we can manually get 5G from the dialer. However, the functionality is there but it somehow needs an update from Oneplus to add 5G from the preferred network. I really hope Oneplus would fix these issues.

what i fear is that this maybe a sign of exclusivity meaning the model should stay error free in china only.

If this happens and no movement from Oneplus in the coming updates. Then I guess this will be my last Oneplus.

You can find FAQ in the download link channel, where there will be region switch methods.

This is my first oneplus. I hope they will fix it. I'm giving my device 2 week sale period. If not. I'll keep it for maybe 3 years and will never buy china unit again.

Hi, may I know if this method works on Oneplus 9R?

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
Oxygen OS for OnePlus 9

Hello everyone, I just ordered my OP9, LE2110. It is said that the phone is already runing Oxygen OS 11.2.2.2.LE25DA

All I want is a locked bootloader, non rooted phone, with Global firmware receiving OTA, can it be possible ? Thanks.

It's possible

 

[abdAlmuqtadir]

It's possible

So it's safe to flash via local update, the global firmware over the indian firmware?

yes, but you only can update to newer version

 

[abdAlmuqtadir]

yes, but you only can update to newer version

Thank you for your reply, can you also flash the current version, not being new? And if you want to wipe data / factory reset how do you do without going back to ColorOs ?
