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

[lgv20v30]

EU model (non root) and I haven't actually put a sim in it yet to test network but have read patching modem is simple enough?

In my case after flash modem and start using data of sim card, it either boots loop or shows qualcomm dump screen on Coloros C.44. Not that simple.

ColorOS 12 LE2123_11_C.44 working data with both EE and O2 sims (UK)

Flashed full ColorOS A12 (NOT OOS12) onto my OP9pro last night and have to say I am amazed on how smooth the experience is. Takes about 5 mins to debloat the chinese bloat off of it and its all good.

I am amazed how there aren't other people flashing this on to the device !

Would you share the method you used to do that, with working Google services and Chinese apps debloated? I recently got an OP9Pro CN unit and the seller sent it with OOS12 pre-installed, however I'm really into ColorOS 12.

Thanks in advance.

There will always be an infamous number of trackers on ColorOS, that's why I don't install it.
Just by installing AppManager, with Exodus you can see a lot of trackers just in the launcher, or in the settings, etc..

Ok, but the sad truth is that every OS nowadays have a lot of trackers and we can't fight it anymore if we intend to use a smartphone.

Of course, that's why I focus on the ones that have the least, which is not the case with ColorOS.

I have many minds than Color OS will dissapear because of non-logic limitations.

Hello friend. I saw you have Oneplus CN version like me LE2120. I gave Oneplus 9 Pro for 6 month and here still android 11. Always I try to update says system is up to date. Android 11 here is working 4G well. We don't have 5G yet in Brasil. I want to install ColorOS 12, but via OTA is not working. What you do to work via OTA?
