Can I revert to Android 11 after installing Android 12 if there are problems? There is a rollback?
I have an EU device.

Hello, thanks for the answer. I haven't worked with MSM yet. Is there a guide for?
Here's a guide along with all link
But anyways, you'll need to use MSM to convert your phone to HydrogenOS before upgrading to ColorOS

I tried the Rom. a little bit too buggy for me and too much chinese stuff on it (most of them can be removed). rolled back with MSM to the official 11 build.
thanks anyway.

Step 1: Use MSM to go to HydrogenOS
Link: Link
Step 2: After going to HydrogenOS, use local upgrade to upgrade to COS 12
Link: Link
i would to correct you, step 1 isn't necessary for people who are already on OOS 11 , in China these instructions were given because some users were using Early adopters version of Color OS that was released in September that early adopters version is incompatible with this new update

Just one question..........if that is a closed Beta build, must there not the Playstore included or has OnePlus only choose people from china for closed Beta 🤔🤔 Because people Europe or USA need the Playstore (I know can be installed later) but that's not the right way from OnePlus if it so 😎😎

I haven't flash this build myself so I can't tell if there is any bug, but people have reported that it's certified in Google Play.

Yes, it can work, but I recommend flashing HydrogenOS first in order to maintain Widevine L1, since some people used your method and it got downgraded to L3.

This build is Chinese only, hence no Play Store preinstalled.

Ah ok then OnePlus build 2 builds one for china and one for Europe and USA ?
Another question I'm on a custom ROM right now, when want to test this must i first flash OOS with MSN tool or can I go directly to Hydrogen ?

There's no buid for global right now
You can use the aforementioned MSM on #2 to go directly to Hydrogen, no need to go to Oxygen first
